Accuracy, privacy and compatibility
Browser-only conversion depends on the codecs included in the FFmpeg core and available memory. Unsupported, protected or corrupt input files cannot be converted.
Files are processed locally wherever the browser and third-party libraries permit. Some processing requires downloading additional WASM, fonts, or library files. Never assume that every file format, codec or mobile browser is supported.
Frequently asked questions
Can I extract only part of the audio?
Yes. Enter a start and end time in seconds before processing.
Does conversion upload the video?
The intended processing engine operates in your browser after downloading its WASM files; libraries are obtained from a CDN.
