Video processing stays local
Encoding happens inside your browser. No video is uploaded to ToAudio.
Video compression questions
Up to 100 MiB and 2 minutes per file. Re-encoding can be slow on phones.
Will the file definitely get smaller?
No. Compression depends on the source codec, bitrate, resolution, and movement. A source that is already efficient can produce a similar or larger file.
Why can video compression take a while?
The browser must decode and re-encode video frames. Slower phones and larger clips need more time and memory.
What format do I get?
A broadly playable MP4 with H.264 video and AAC audio if the original has an audio track.
Is my video uploaded?
No. FFmpeg WebAssembly runs in your browser and the video stays on your device.
