Frequently Asked Questions

Our tool uses FFmpeg.wasm – a WebAssembly port of the famous FFmpeg library – to perform the conversion directly inside your browser. No file is ever uploaded to any server; everything stays on your device, guaranteeing absolute privacy and security.

Yes, it’s 100% free with no watermarks, no sign-up, and no limits on the number of conversions. The only “limit” is your device’s processing power – extremely large files (>500MB) may take longer or might be better handled by a desktop app.

Practically all common formats: MP4, WebM, OGG, MOV, AVI, MKV, FLV, WMV and many more. Under the hood FFmpeg can handle hundreds of codecs and containers.

Absolutely not. The entire process runs offline inside your browser. Your video never leaves your computer – we have no way to access, store, or even see your file.

Yes, you can. However, processing time is proportional to the duration and resolution. For best results, we recommend videos shorter than 60 minutes. If your browser supports SharedArrayBuffer, multi-threading will speed up the conversion significantly.

Currently we output MP3 because it’s universally compatible with every smartphone, tablet, car stereo and media player. It provides an excellent balance between file size and audio quality. Future updates may add more formats (like AAC or WAV) based on user demand.

Yes! The interface is fully responsive. Mobile browsers can convert videos, but please be mindful that large files may consume significant battery and resources. We recommend Wi-Fi and a reasonably modern device.

Some uncommon video codecs may not be fully supported by the WebAssembly version of FFmpeg. If you encounter an error, try converting the video with a different tool first (e.g., Handbrake) to a standard MP4, then use our tool. Also, ensure your browser is up-to-date.

On the first use, the FFmpeg engine is downloaded (~30 MB) and cached in your browser. After that, the tool works completely offline – no internet required. Great for privacy and remote situations!
