Frequently Asked Questions
Is the conversion really happening in my browser?
Yes! We use FFmpeg compiled to WebAssembly (WASM). Your files stay on your device at all times — nothing is uploaded to any server.
Are there any file size limits?
There are no artificial limits. The only constraint is your device's available memory. Most devices handle files up to several gigabytes without issues.
Which formats are supported?
All major video formats (MP4, MOV, AVI, MKV, WebM, FLV) and audio formats (MP3, WAV, FLAC, OGG, AAC, WMA) are supported.
Do I need to create an account?
No. The converter is completely free and works without any account or registration.
