Capify’s video converter is a fast, free, in-browser tool for converting video and audio files without uploading them anywhere. Most online converters send your media to a remote server, add watermarks, or cap your file size. This converter runs entirely on your device using the modern WebCodecs API, so your files never leave your computer. There are no uploads, no watermarks, no sign-up, and no limits on how many files you convert.
Convert MP4 to WebM, WebM to MP4, MOV to MP4, MKV to MP4, and AVI to MP4 in just a few clicks. Choose from H.264, H.265/HEVC, VP9, and AV1 codecs, adjust the quality, and downscale to 1080p, 720p, or 480p to compress video online and reduce file size. Whether you need a universal MP4 for sharing, a lightweight WebM for your website, or a MOV for editing on a Mac, the converter has you covered.
Need just the sound? Extract audio from any video and save it as MP3, M4A (AAC), or lossless WAV. Want something shareable? Convert MP4, MOV, or WebM clips into looping animated GIFs with a custom frame rate and width. Every conversion happens locally and downloads instantly when it’s done.
