Frequently Asked Questions
How does browser-based video conversion work?
Our converter uses the WebCodecs API, a modern browser technology that provides direct access to video encoding/decoding hardware. This means your GPU handles the conversion, making it extremely fast while keeping everything local on your device.
Which browsers support this converter?
WebCodecs is supported in Chrome 94+, Edge 94+, and Opera 80+. Safari and Firefox have limited support. For the best experience, we recommend using Chrome or Edge.
Why convert to MP4 vs WebM?
MP4 (H.264) offers the widest compatibility across devices, apps, and platforms - ideal for sharing. WebM (VP8/VP9) provides excellent compression for web delivery and is royalty-free, making it perfect for websites.
Will converting reduce video quality?
Re-encoding always involves some quality trade-off, but our converter uses optimized settings to minimize loss. For lossless needs, consider using the same codec family (e.g., H.264 to H.264 container change).
Can I convert multiple videos at once?
Currently, the converter processes one video at a time for optimal performance. After completing one conversion, you can immediately start another.
Conversion Speed Tips
Conversion speed depends on your device's hardware. Modern computers with dedicated GPUs will process videos significantly faster. For best results, close other browser tabs and applications during conversion.
