Which format should I choose?

MP4 is the most universally compatible format. WebM is great for web use and smaller file sizes. MOV is preferred for Apple devices. AVI is a legacy format with wide support.

Will the quality be affected?

Converting between formats involves re-encoding, which may slightly reduce quality. Choose 'High' quality to minimize loss. Converting from a lossy format won't improve quality.

Can I convert multiple videos at once?

Yes! Add multiple video files and they will be converted one by one. Download them individually or as a ZIP file.

What input formats are supported?

We support MP4, WebM, MOV, MKV, and AVI input files. Output is available in MP4, WebM, MOV, or AVI format.

Why is conversion slow?

Video conversion runs in your browser using WebAssembly, which is slower than native software. Speed depends on your device's CPU, video length, and quality settings.
