MOV to MP4.

Apple devices record MOV. Windows, editors, and upload forms often want MP4. This converts between them on your own machine, so your footage never touches a server.

Why your MOV will not open

MOV is Apple's QuickTime container. iPhones, iPads, and Mac screen recordings all produce it, and inside Apple's world it plays perfectly. Step outside and things get patchy: Windows machines without QuickTime components, older editing software, and plenty of upload forms either refuse the file or mangle it.

MP4 with H.264 video and AAC audio is the format everything accepts. The two containers are close cousins, so converting between them is fast and the quality holds up. That is exactly what this tool produces.

How it works

Step 1

Drop your MOV in

Drag the file onto the panel or click to browse. It is read straight from your disk, not uploaded.

Step 2

Pick a quality

Balanced is right for almost everything. High keeps close to the original for further editing. Small trades detail for a much lighter file.

Step 3

Download the MP4

The first conversion downloads the encoder (about 31 MB, once), then it is instant on repeat use.

Questions

Is my file uploaded anywhere?

No. The video encoder is compiled to WebAssembly and runs inside this browser tab, so your file is read from your disk, processed by your CPU, and saved back to your downloads folder. There is no upload endpoint. You can confirm it by opening your browser devtools network tab, or by disconnecting from the internet once the page has loaded.

Will iPhone videos work?

Almost always, yes. Newer iPhones record HEVC (H.265) by default, and this tool converts that to the H.264 MP4 everything accepts. If a particular file fails to load, your browser build may lack that codec: try Chrome or Edge, or set the iPhone camera to Most Compatible in Settings, Camera, Formats.

Does converting lose quality?

Converting between formats means re-encoding, so there is always some loss in principle. At the High setting it is not something you will see. Balanced is visually very close on normal footage. Small deliberately trades detail for size.

Does it add a watermark or a length limit?

No to both. There is no watermark, no clip limit, and no daily quota, because there is no server cost for us to recover. Convert as many files as you like.

Is there a file size limit?

The tool holds your file in browser memory, so it is capped at 600 MB. That covers most screen recordings and phone clips. For anything larger, trim it down first or use a desktop encoder.

Can it convert MP4 back to MOV?

Not here, and you rarely need to: every tool that opens MOV also opens MP4. If a workflow genuinely demands MOV, the Recording Studio app exports MOV directly on the premium tier.
