Frequently Asked Questions
Quick answers to common questions about converting video formats in your browser.
The conversion uses a WebAssembly-powered media engine that runs in your browser. Videos are processed locally and are not permanently stored on our servers.
MP4 (H.264) is usually the safest choice for broad compatibility across devices, browsers, and platforms. WebM is great for modern browsers, and AVI or MKV can be useful for local playback.
Quality can change depending on your chosen CRF value, resolution, and bitrate. Lower CRF values and higher bitrates keep more quality but result in larger files, while higher CRF and lower bitrates reduce file size with more visible compression.
Some formats or codecs may not be supported by your browser for inline playback. Even if the preview fails, you can still download the file and play it in a desktop media player that supports the format.
The converter may work on some modern mobile browsers, but video processing is resource-intensive. For large or long videos, a desktop or laptop will give you a smoother experience.
No installation is required. Everything runs in your web browser using WebAssembly-based FFmpeg. Just open the page, upload a video, pick your settings, and download the converted file.
