Popular video conversions

A free online video converter for MP4, MOV, MKV and more

RunConvert's video converter changes videos between MP4, MOV, MKV, AVI, WebM, WMV, FLV and dozens of other formats, without installing any software. Upload a clip, choose the format you want and download the converted video when it's ready - large files included, up to 1GB on the free plan.

Typical uses: convert iPhone MOV videos to MP4 so they play on Windows and Android, turn MKV files into MP4 for TVs and phones, save a clip as a GIF to share, or make WebM for websites. You can also pull the soundtrack out of any video by converting it to MP3, WAV, AAC or another audio format.

The settings button lets you choose the video codec, change the resolution (for example 720p or 1080p) and adjust other options before you convert.

Which video format should you choose?

mp4
The safe choice. Plays on every phone, browser, TV and editing app.
mov
Apple's format, used by iPhones and Final Cut. Best kept for Apple workflows.
mkv
Holds several audio tracks and subtitles in one file. Popular for movies, less widely playable.
webm
Made for the web. Small files that play in modern browsers.
avi
An older Windows format. Convert to MP4 for smaller files and wider support.
