Update – 2023-04-30
I am taking down the torrent. Instead, I recommend using Kiwix, it’s a reader for ZIM files, you can have a local copy of many different websites including Khan Academy. It is fast and easy to use. At the moment of writing this, they have a 180 GBs file taken only a month ago so 2023-03 and there is 9716 webm video files in it so it seems to be complete with all subtitles.
Download Kiwix at www.kiwix.org then head over to download.kiwix.org and look into the folder zim then other, you will find the latest Khan Academy videos.
Introduction
Khan Academy is a website offering thousands of free educational videos on a lot of different subjects: Mathematics, Science, History, Economics, Astronomy, Art history and a lot more! The Wikipedia article of Khan Academy has more details on what it is exactly.
The videos are available on their website where you can (optionally) log in, this will give you some features like tracking what you have watched, commenting, asking questions to other people and doing tests and when you pass them successfully, the website will skip videos that you do not need to watch because you have understood a specific subject well. When you use their website, the team behind Khan Academy also track what you are doing so they can improve their website. There is no doubt that by using their website you can learn faster than if you download and watch all the videos on your computer.
However, for various reasons it might be best to download them. To share with people who do not have access to the internet is one of the main reason.
How to download the videos
Download a torrent software, many are available. If you do not know what bittorrent is, first read the Torrents 101: How Torrent Downloading Works article. One torrent software that is free and open source is Deluge. Available for Windows, OS X and Linux. Install it, open it, click on File > Add Torrent > File and select the torrent file that is posted at the top of this page.
Information on the torrent
The torrent is available at all times. It is extremely well organized with descriptive titles. We recommend using the free and open source VLC Media Player to play them.
Here’s a preview of some of the videos and how they are organized.

FAQ
How do I only download specific videos?
One of the most useful feature with torrents is that you can download just what you need. Every torrent software has this option. In Deluge, click on your torrent and look at the Files tab at the bottom, you can right-click on folders and select “Do not download”.
When will a new torrent file be released with new videos?
There is no release date. This torrent is voluntary work so it happens only when we find the time to make a new one.
A new torrent is out, can I download it over the old torrent I had so as to save bandwidth?
Khan Academy regularly change the structure, folder names and filenames so it is better to delete everything and start downloading the new torrent.
Why is some filenames of video cut-off?
Windows filesystem, unfortunately, has a limit of around 255 characters for the complete path with the filename. So we have implemented a limit of around 200 characters for the path and the filename of each videos. The remaining 55 characters is left for the path that the user will download the torrent (i.e. C:\Users\name\Downloads).
How do subtitles work exactly?
A subtitle file, which has an extension .srt, is just a text file containing all the subtitles of a video. To be able to use it, the subtitle file must have the exact same filename as the video and be in the same folder as the video. By just opening the video with VLC Media Player, it will automatically read the subtitle file.
To copy the subtitles files in the same folder as the videos, unzip the language you would like from the Subtitles folder and just copy all the folders of your language into the folder video so as to merge them. It will place all the subtitles files in the right folder. Note that there isn’t subtitles files for every video. Unfortunately, not all videos are translated.
Lots of videos are missing. For example in the “Math/High school geometry/01 Geometry foundations/”, look at the numbers in the beginning of the file names, the first one is 001, and the next is 005, 3 videos are missing here.
There are some dead torrents from previous years that were complete. For example if you take a look at the filelist of this dead torrent in the same section (Geometry), you can see that it’s completely ordered and not a single video is missing:
http://www.legittorrents.info/index.php?page=torrent-details&id=58dfa32d9b747e6ae9e2b8e6717a528bd002be48
That is normal, nothing is missing.
We cannot compare now because the videos all changed on the website. But take a look at https://www.khanacademy.org/math/geometry/hs-geo-transformations you can see that the first title is “Getting ready for performing transformations” but it is not a video. In my script, it will be 001 but since it is not a video. The second one is “Euclid as the father of geometry” and it is a video so you will see “002 Euclid as the father of geometry”.
Back then, every link was a video but not anymore. Sometimes they have articles, quizzes or tests which are not videos. I can modify my scripts to not have missing numbers but I prefer not too.
It is better to use Khan Academy from their website. My torrent is just to make it available for people without internet.
Khan academy’s organization of videos is a catastrophe, that’s the reason I’m trying to avoid their website. It seems that the videos were organized sanely some years ago and suddenly they got insane at some time and decided to ruin everything. I would be really grateful if you could reseed your old torrents. I tried many of them, there’s no seeders. If you can’t, do you know any other way to download videos in the same order that they were organized in the past? like 2015? thanks a lot
I agree it was better before but it’s still not bad how they are organized.
All old torrents and the data are gone, I just keep one copy of the most recent.
Use a renamer software, add a numbering 001, 002, 003 at the start and then delete the old numbers between character 4 and 7. This will be what you are looking for.
Maybe the next torrent I do, I can made the videos follow the numbers properly but we are going to miss the information that when a number is missing, it means there’s an article or a script to do.
Hey. I found the torrent and am downloading it now. It’s going super slowly (ETA: 46 days), If your seed box isn’t up and running, please get it going. Thank you.
Seedbox up and running, no problem. I see you downloading at around 130 KB/s, indeed it is slow. Everything seems to be working fine here however. I just tried the torrent on my computer and I’m downloading at the maximum of my internet connection.
Please Seed as there is Zero Seeder Now
I think there was a problem with my seedbox, I restarted it and it looks fine now!
there are no seeders :<
My seedbox server is down, doing some maintenance, I will check back tomorrow!
Back online and seeding!
I need the math & physics parts. As i have to download 42 GB @ 30kb/s for a few hours a day, this will literally take me months to complete. Please seed !
I’m there and seeding with my seedbox very fast but there is no one at the moment downloading.
I Want to say Thank You.
Very very carefully classified and maintained. Thank you for the efforts. Specially for the Math. It was very difficult to arrange everything. Many videos are repeated.
You made it simple. Great work
Thanks for the comment! Indeed, lots of duplicate videos on their website all around. I have a special tool to remove those and just keep one copy. I will make a new version soon, wanted to do it during christmas time but didn’t find the time.
Thank you so much, Zurd. God bless you and your hard work. The world needs more people like you.
Hi, could you please seed the torrent again?
I am seeding at the moment at 23 MB/s ! I’m checking it every sunday to make sure it is still running. There hasn’t been a problem in over a month now.
I see. For some reason my torrent client initially failed to connect to the swarm, but it’s working now.
Anyway, thank you very much for providing this torrent. I was using youtube-dl to archive all Playlists from the Khan Academy YT channel, but Youtube temporarily locks me out every time I download more than a couple hundred videos from the same IP address (even if I set a delay of 1 min between each download). Downloading your torrent is a much more effective method of getting the videos, that’s for sure.
Thanks again.
Cheers
Hey, is anyone still seeding this? It’s a great torrent, but unfortunately only 1 seeder giving me roughly 20 KiB/s :(.
Much appreciated!!
Yup, I’m still here, the torrent on my seedbox was stopped for an unknown reason, I’ve restarted it and it’s seeding right now but not very fast.
Thanks! Im seeding back rn!
This torrent is not complete, and I cannot find what I am looking for anywhere else. You mentioned a Bash script and PHP, could you post those somewhere? That might be helpful to many. Thanks.
Hi, check out https://www.zurd.ca/khanacademy.zip it’s all in there, php and bash scripts, it’s possible that the khanacademy webpage has been modified so the script will have to be modified, haven’t take a look in a long way unfortunately. It’s in my to do list, just not there yet :)
This is incredibly useful.
You have all my gratitude for your work.
I will keep this torrent seeded.
Have you been downloading the videos manually, or have you got a trick up your sleeve ?
Manually would take way too long. I started with a BASH script that download and rename all the videos. Then it wasn’t practical so I remade it into PHP. It’s working quite good now :)
Your dedication is very commendable. I wish we all had a sharing at heart.
Have you thought about hosting your automate on github ? It would certainly be appreciated by a lot of Khan users.
The road to your blog was a bit strenuous, as Google bans “torrent” related keyword and searches
No need to put it on github I would say, it’s just a small personnal project :) Use duckduckgo.com not google!
Dude or sir are you from finland, thats the only live peer for the past 24-hours.
I am not much of a commenter, but i highly appreciate the effort you’ve made to compile and keep it running, bless you man~!
Thank you!
Are you planning on uploading the collage class videos?
I wish I could, I’m just quite busy. I’ll try to re-do the whole thing in a few weeks instead.
The torrent has stopped at 7.8 % and turned into red, please seed I really been waiting for this to download. Its very important for me. I rely on these lectures. So please seed.
Thank you
There was a server migration of my seedbox which is why it was down. It’s up and running again!
please seeeeeed!
There was a problem with the hard drive on the seedbox, everything was lost which is why I cannot seed anymore. I will make a new torrent very very soon (hopefully today!) with all new contents!
New torrent is finally out!
fantastic! been waiting for it. thanks for all your hard work!
You’re welcome!
It’s Such An incredible Torrent but like stuck at 93%. I need to move the files to an external hard drive so is there something that can be done about getting that 7%?
There was a problem with the hard drive on the seedbox, everything was lost which is why I cannot seed anymore. I will make a new torrent very very soon (hopefully today!) with all new contents!

Hi Zurd,
Thanks so much for the new KA torrent.
I looked and I did not see Probability/Statistics, any Calculus, DiffEq or Linear Algebra videos. I’m wondering if you will re-release the torrent with those videos included?
Thanks
Hi, if you look at https://www.khanacademy.org/library, most of the videos in “Math by subject” are already included in “Math by grade” which is why I didn’t include videos from “Math by subject”. I realized now it was a mistake. I will release a second torrent which will be “Math by subject” only. It will complement the first one!
Ohh, ok. Thanks for the clarification and the hard work! I’m actually using youtube-dl right now to download section by section from KA, just to stay organized. So far it’s great, though a many-step process. I haven’t figured out yet how to run youtube-dl on any of the base index pages and result in an organized output. I think your new torrent will look a lot like what I’m working on.
Thanks!
Hi Zurd. Thanks for all of this. I would like to know when will you make the new “math by subject “torrent. I have decided to shut down my internet to stop wasting time but i do need khan academy for studies so downloaded everything offline. I request you to make the “math by subject”(with calculus).
Do you mind sending a link of the new torrent to my email as i am shutting my internet down from today.
Thanks again!
Email : akshayraman1002@gmail.com
incredible torrent, are you the only one seeding ? it’s quite impressive and will help a lot of people, can’t thank you enough for this.
There was some people seeding in the past, not sure if they are still around. The torrent is on a seedbox so the speed shouldn’t be an issue :)
Thank you so much.
please can u update the torrent and add the new videos from khan academy?
Quite busy at the moment but I will do it for sure in just a few months :)
New torrent is finally out!
Thank you very much Zurd! Very kind of you to do so much and for free! You saved an unbelievable amount of time, by no doubt taking an unbelievable amount of your time. God bless!
And thank you to the seeders as well!
My pleasure! Though this torrent is getting quite old, i’ll try to prioritize making a new one in the next few weeks!
cool. thanks
can you please seed. i am from uzbekistan and my internet speed is 30kb/s.
Torrent was in paused state unfortunately. It’s running again now!
Bro, there’s only one seeder in this torrent. such a same for great content.
Yes I’m the one seeding. It is on a seedbox with a 20 Mbps upload speed so there should be a good download speed.
Are you planning on doing another update this year? Thanks for your hard work, I imagine creating this torrent is very difficult!
I will add in my to do list to create a new torrent. This year for sure since it’s been a long time I haven’t done one!
First torrent was hard to do but now it’s quite easier since I have a script and the procedure written down, it just take a bit of time :)
Excellent resource. Just started to download, but it stopped midway. No seeds for the last two days. Please help.
Sorry about that, it should be seeding now!
there is no seeders..pls update file
Sorry about that, it should be seeding now!

zurd could u help me in giving live peers
hey there Zurd!
I am going to download the videos but since you’ve said that you are going to update the torrent, should I just download them now? or wait or something? am I going to miss something?
thanks.
Go ahead and download everything, I’m not ready yet to make a new torrent. I’ll make a new one this summer so there’s still a few months left! :)
THANK YOU SO MUCH for adding subtitles.

I know it’s been a year since you last posted this new torrent, but I’d just like to thank you for setting this up!
Well last torrent was 2015-07-29, so it’s been 5 months and a half not one year! I will release another torrent with the latest videos in a few months, stay tuned! Thanks for your comment!
This is wonderful. Thank you very much. This is great help for people who can’t access Khanacademy directly. Thanks a lot.
This torrent is unseeded, which is too bad because I could really use it. Can you drop me an email or something if you start reseeding, Zurd? :)
Sometimes this torrent goes to Pause in my seedbox. No idea why but I always restart it. I check it around once a week. It’s been running for at least the past 3 days without problem!
sir, I am unable to download it using bitcomet. what should i do as now it has no seeder ……. please reply soon.
Like I said below to someone else, there was a problem with the seedbox, it lasted just a few days though. We are 4 peers connected at the moment, working quite fine!
Sorry Sir/Ma’am but torrent has stopped on 1.5% and not proceeding because of no seeders.
I request you to look into this matter and please rectify the problem. i will be very grateful to you.
People are still seeding, it’s all working fine.
Unable to download in that torrent, not connecting to peers. Error in the tracker. Can anyone fix it ?
There was some problem with the seedbox at that time which lasted for a few days. It’s been seeding fine for quite some weeks now!
Thank you, so much. I think it would be so much better if you could include each video subtitle in the torrent also and I would be very thankful if you show me anyway that I could get all the subtitles by my self. Thank you.
I always wanted to add the subtitles too but kind of forgotten all about it!
I will see what I can do in the next torrent!
Thank You
