Frequently Asked Questions

Are my videos uploaded to a server?

No. All processing is powered by FFmpeg.wasm and runs entirely in your browser. Your files never leave your device.

What video and audio formats are supported?

Video: MP4, AVI, MOV, MKV, WebM. Audio: MP3, WAV, OGG, AAC, FLAC, M4A. Output formats depend on the tool selected.

Why is processing slow on my device?

Since FFmpeg runs in your browser, processing speed depends on your device's CPU and memory. Large or high-resolution files take longer. Try reducing resolution or trimming the file first.

Is there a file size limit?

There is no hard limit, but browser memory constraints mean files over 500 MB may cause issues on some devices. For best results, keep files under 200 MB.

Can I convert a video to GIF?

Yes. Use the "MP4 to GIF" tool. You can adjust width and frame rate to control the output GIF size and quality.
