About this conversion
Only the container and encoding change; picture and sound are re-encoded in your browser.
Good to know
Recompressing a lossy file costs a little more quality.
The video is re-encoded, which takes time depending on length and device.
The audio track is kept unless you switch it off.
How it works
Your browser can use hardware-accelerated video encoding for this conversion, which is much faster than software.
This conversion uses ffmpeg compiled to WebAssembly. It is loaded only when needed and runs in a background thread.
Your browser can
- Built-in image codecs
- Hardware video (WebCodecs)
- Multiple threads
- Create AVIF natively
If something is missing, the conversion takes a little longer but still works.

Frequently asked questions
Are my files uploaded to a server?
No. The conversion runs entirely in your browser with local code. Your files never leave your device, and there is no upload.
Is there a file size limit?
There is no limit on our side, but your browser memory is. Images work for very large files; for videos, files above a few hundred megabytes can fail on devices with little memory.
Will the quality suffer?
That depends on the target format and settings. Use the quality option to balance size and detail; lossless targets keep everything the source contained.
Which browsers are supported?
Current versions of Chrome, Edge, Firefox and Safari. Fast hardware paths are used where available, with a compatible fallback otherwise.
