FAQ

What is VideoWit?

VideoWit is a free set of browser video tools: convert video to GIF or MP3, compress video and turn MP3 into MP4. The tools run in your browser, so your files are processed on your device and never uploaded.

How does VideoWit work?

Each tool runs ffmpeg, compiled to WebAssembly, inside your browser tab. The first time you open a tool, your browser downloads the engine (about 32 MB) and caches it; after that, conversions start right away.

Is VideoWit free?

Yes. Every tool is free, with no account, no watermark and no daily limit.

Does VideoWit upload my files?

No. The tools run ffmpeg.wasm in your browser, so your files never leave your device.

Which tools does VideoWit have?

MP4 to GIF, Video to MP3, a Video Compressor and MP3 to MP4, plus format pages for MOV to GIF, MOV to MP3, AVI to MP4 and WAV to MP3.

Which formats work?

The video tools read MP4, MOV (including iPhone HEVC), WebM, MKV, AVI and most other formats. MP3 to MP4 takes MP3, WAV, M4A, AAC, FLAC, OGG and Opus.

Does VideoWit work on a phone?

Yes, in Safari or Chrome on iPhone and Android, for files up to 100 MB. Phones convert more slowly than computers.

How big can my files be?

Up to 500 MB on a computer (250 MB for GIFs, 100 MB for MP3 to MP4) and 100 MB on a phone, because the whole file is held in your browser's memory.
