Quick answer: To convert NUT to 3GP, add the NUT file to the iHateFiles NUT to 3GP 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. NUT is a format most software has stopped opening. 3GP is not.
Should you convert NUT to 3GP?
Yes. NUT is a format most current software no longer opens, so converting it is the reliable way to keep watching it. 3GP is a reasonable target; MP4 is the safest.
The picture is re-encoded
A NUT usually holds whatever codec FFmpeg was asked to put in it. This writes H.264 Baseline video with AAC sound at 96 kbps into the 3GP. Both sides are compressed with loss, so this is a second generation: leave the quality at its default or higher, because the encoder is working from NUT artefacts rather than the original.
Extra tracks may not survive
A NUT can carry several audio tracks. 3GP holds one picture and one sound, so this conversion keeps the main video and the first audio track. If you need the subtitles, save them first with Extract Subtitles.
Where the 3GP will play
3GP plays on old feature phones, VLC, and most modern players.

What usually goes wrong
About the NUT. If you have a NUT file it almost certainly came out of a script using FFmpeg defaults, rather than from any deliberate choice.
About the 3GP. Converting a 3GP does not improve it. The detail was never recorded, and upscaling only makes the file bigger.
How to convert NUT to 3GP
- Add your NUT file. It is read from your disk and stays there.

Questions
How do I convert NUT to 3GP?
Open this page, add your NUT 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 NUT to 3GP 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 3GP lose quality?
3GP 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 NUT files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
