Free Video Converter Online — Convert MP4 AVI MOV WebM MKV

Convert videos between MP4, AVI, MOV, WebM, MKV, FLV and GIF instantly. Browser-based, no software required. Powered by FFmpeg for maximum compatibility.

Video format guide: which to choose

MP4 (H.264): the universal standard — plays on every device, platform and browser worldwide. Best for sharing, social media upload and general use. WebM (VP9): Google's open web format — smaller than MP4 at equal quality. Ideal for HTML5 video embeds and web performance. Supported by Chrome, Firefox and Edge natively. MOV (QuickTime): Apple's native format — highest quality for Final Cut Pro and iMovie workflows. Large file sizes. MKV (Matroska): open container supporting multiple audio tracks, subtitle streams and chapters. Popular for media servers (Plex, Kodi) and archiving. AVI: legacy Windows format — wide software compatibility but no modern compression support. GIF: convert short clips to animated GIF (max 15 seconds recommended).

Quality and resolution settings

Choose output quality from low (smallest file, visible quality loss) to high (larger file, near-original quality). Optionally change the output resolution: convert 4K to 1080p, 1080p to 720p, or keep the original. Changing resolution is the most effective way to reduce file size alongside codec conversion.

FAQ

Is quality preserved after format conversion?

A slight quality loss is unavoidable during transcoding (re-encoding). Use the "high quality" setting to minimize this. Converting between the same codec (e.g. H.264 to H.264) at high quality produces nearly identical results.

Can I convert MP4 to MOV without quality loss?

Near-lossless conversion is possible at high quality settings. Since both MP4 and MOV can contain H.264 video, the video stream can be copied without re-encoding when the container is the only thing changing.

What is the maximum video file size?

Videos up to 500 MB per upload are supported.

Can I convert video to MP3 or other audio-only formats?

For audio extraction from video, use our dedicated Extract Audio from Video tool for better control over audio quality and format.

Which format is best for uploading to YouTube?

MP4 with H.264 codec is YouTube's recommended upload format. For highest quality uploads (4K/HDR), MOV or MKV with H.264 or H.265 are also accepted.

Can I convert a video to GIF?

Yes, for short clips (under 15 seconds). Longer clips are better served by our dedicated Video to GIF tool which offers more control over frame rate and palette optimization.
