Convert Any Video to MP4, Free and Without a Watermark

An iPhone video that won't play on a Windows PC, an MKV file a website rejects, a screen recording in a format nothing else opens — converting video to MP4 is one of the most universally useful file operations there is, because MP4 plays on essentially everything: every browser, every phone, every social platform.

Why MP4 Is the Format Everything Plays

This tool converts any video format — MOV, MKV, AVI, WMV, FLV, WebM — to MP4 using FFmpeg with H.264 video and AAC audio, the exact combination that's guaranteed to play back on every device, browser, and platform without a missing-codec error.

No Watermark, No Hidden Size Cap

Several popular free video converters add a watermark to exported files unless you upgrade, or quietly cap free conversions at a size well below what a modern phone video actually needs. This tool does neither — convert full files without a watermark stamped across them.

The iPhone HEVC Problem

iPhones record in HEVC (.mov) by default, which plenty of older software, some Android devices, and various websites simply can't play. Converting to MP4/H.264 solves this instantly and is one of the single most common reasons people search for a video converter in the first place.
