Preparing Video for Its Final Destination
The best conversion settings depend on where the video will be used. A file intended for a website may need different compression from one being edited locally or uploaded to a social platform. Resolution, frame rate, codec, bitrate, and audio settings can all influence the resulting file, so conversion is not simply about changing the extension displayed at the end of the filename.
About Video Converter
Video files can use different containers and codecs, and compatibility can vary between devices, browsers, editing applications, and social platforms. MP4 is widely supported, while formats such as WebM are commonly associated with web delivery and other formats may be useful in specific workflows. Converting a video can therefore be necessary when the original file does not match the requirements of its destination.

FAQs
What video formats are supported?
Our converter supports MP4, WebM, AVI, MOV, and MKV formats. You can convert from any of these formats to any other format.
How does browser-based video conversion work?
We use FFmpeg.wasm, which is FFmpeg compiled to WebAssembly. This allows professional video conversion to run directly in your browser without uploading files to a server.
Why does the first conversion take longer?
The first time you use the converter, it downloads ~30MB of FFmpeg files. These are cached in your browser, so subsequent conversions are much faster.
What's the maximum file size?
We recommend files under 200MB for optimal browser performance. Larger files may work but could be slow or cause memory issues.
What do the quality presets mean?
Quality presets control video bitrate: Low (500k), Medium (1000k), High (2000k), Ultra (5000k). Higher bitrates mean better quality but larger file sizes.
Is my video uploaded to a server?
No! All conversion happens in your browser. Your videos never leave your device, ensuring complete privacy.
How long does conversion take?
Conversion speed depends on your device and video size. Typically, it processes at 0.5-2x realtime speed. A 1-minute video might take 30 seconds to 2 minutes.
