About Convert1

Convert1 is a media converter. It focuses on the files people most often need in another format: phone videos, screen recordings, music, voice memos, GIFs and the photos that sit next to them.

Everything runs inside the browser tab. Video is encoded through WebCodecs where the browser offers it, and through FFmpeg compiled to WebAssembly where it does not; images go through libjpeg, libwebp and libavif ports. Because the work happens on your device, there is no upload, no file size cap and no queue.

Convert1 is free, needs no account and adds no watermark.
