Fast, private browser video conversion

Bright Video Converter is designed as a simple single-file converter. The browser sends one selected video to the conversion server for processing. Conversion uses server-side FFmpeg, so mobile devices do not need to perform the heavy transcoding locally.

Convert video files online

Convert videos to MP4, WebM, MOV, MKV or AVI, create a GIF, or extract MP3 audio. The converter is designed for Chrome, Safari, Edge and mobile browsers, with server-side FFmpeg processing for better codec support than browser-only conversion.

Popular video conversions

Use it for MOV to MP4, MKV to MP4, MP4 to WebM, AVI to MP4 or video to MP3. Uploaded files are temporary processing files; production deployment should keep automatic cleanup enabled and enforce file-size and rate limits.
