Quick answer: To convert Y4M to GIF, add the Y4M file to the iHateFiles Y4M to GIF converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. Y4M is a format most software has stopped opening. GIF is not.
Should you convert Y4M to GIF?
Do this for a short loop that has to play where video does not, such as email or a chat client. For anything longer than a few seconds, a video file is smaller and looks better than the GIF.
Nothing is discarded
Y4M and GIF are both lossless, so every pixel survives the move intact. Convert back and forth as often as you like; the image does not degrade.

What usually goes wrong
About the Y4M. A few seconds of Y4M can be larger than a whole film in MP4. That is the format doing its job.
About the GIF. Halving the width of a GIF cuts the file size by roughly three quarters. Dropping the frame rate helps almost as much. Trimming the length helps least.
How to convert Y4M to GIF
- Add your Y4M file. It is read from your disk and stays there.
- Check the settings. The output format is already set to GIF.
- Press convert and the GIF file is saved back to your device.
Questions
How do I convert Y4M to GIF?
Open this page, add your Y4M file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this Y4M to GIF converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to GIF lose quality?
GIF is a lossy format, so some detail is discarded. The quality control on this page decides how much. The default is set high enough that most people cannot see the difference.
Can I convert several Y4M files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
