Frequently Asked Questions
What video formats can I convert?+
You can convert to MP4 (H.264), WebM (VP8), AVI, MOV, and animated GIF. As input, most common formats work, including MP4, WebM, MOV, AVI, and MKV.
Why is video conversion slow?+
Video encoding is CPU-intensive and runs via WebAssembly in your browser, which is slower than native software. Shorter videos and lower resolutions process much faster.
What does the quality slider do?+
It controls the CRF value (18–40). A lower CRF means better quality and a larger file; a higher CRF means a smaller file with more visible compression.
Can I convert a video to GIF?+
Yes. Choose GIF as the output format — the tool creates an animated GIF at 10 frames per second, optionally scaled down to 1080p, 720p, or 480p to keep the file small.
Is my video uploaded to a server?+
No. Everything runs locally in your browser using FFmpeg WebAssembly. Your video never leaves your device.
