Not every player opens every file. An iPhone MOV will not play in some Windows apps, an MKV rip is refused by most phones, and an old AVI stalls in the browser. Converting to MP4 gives you one file that works everywhere.
Choose the output format. MP4 uses H.264 video with AAC audio and is the safe choice for phones, TVs, PowerPoint and social apps. WebM uses VP9 with Opus and is ideal for websites and Discord. The converter re-encodes the video into the chosen codec.
Conversion runs inside your browser with FFmpeg WebAssembly. The file is read from your disk and written back as a download – no server, no account, nothing added.
iPhone MOV to MP4
iPhones record HEVC in a MOV container. Converting to MP4 gives H.264, which plays on Windows, Android and older TVs without extra codecs.
Pick WebM for the web
VP9 WebM files are smaller than MP4 at similar quality and play natively in Chrome and Firefox. Encoding is slower, so keep clips short.
Large files
Files under about 300 MB and 1080p convert in a minute or two. 4K works but is slow, and browsers hit a memory limit around 1 GB. Compress or trim first if needed.

Frequently asked questions
Does converting reduce video quality?
The video is re-encoded, so some detail can change. On the High setting the difference is not visible on a phone or laptop screen.
Which formats are supported?
Input: MP4, MOV, WebM, MKV, AVI, M4V, 3GP and most files FFmpeg can decode. Output: MP4 (H.264 + AAC) or WebM (VP9 + Opus).
Is there a file size limit?
Browser memory allows roughly 1 GB. Files under 300 MB and 1080p are comfortable.
Is it free and private?
Yes. No sign-up, no watermark, and the file never leaves your device.
