Common Questions
What video formats are supported?
Most common video formats are supported including MP4, WebM, MOV, AVI, MKV, and more. FFmpeg handles the conversion internally regardless of the source format.
Is the audio quality preserved?
Yes. You can select bitrates up to 320kbps for near-lossless quality. The output quality depends on the original video's audio track—we don't add any additional compression beyond your selected bitrate.
Why does the first conversion take longer?
The first time you use the tool, it downloads the FFmpeg WebAssembly library (~30MB). This is cached by your browser, so subsequent conversions start instantly.
Is there a file size limit?
There's no enforced limit, but very large videos (500MB+) may be slower depending on your device's memory and processing power. For best results, keep files under 200MB.
Does this work on mobile devices?
Yes, but performance varies by device. Modern smartphones with sufficient memory can process videos, though desktop browsers typically offer better performance for large files.
