Convert MOV to MP4

Drop a MOV file below and press Compress — you get a standard H.264 MP4 that plays on Windows, Android and every website. Choose High quality to keep it looking like the original.

Processed on your device — files are never uploaded.

How to convert MOV to MP4

  1. Choose your MOV file.
  2. Leave High quality selected for a near-identical copy.
  3. Press Compress video.
  4. Download the MP4.

Why convert MOV to MP4?

MOV files can fail to play on Windows, Android and some websites, especially when they contain HEVC video. Converting to H.264 MP4 makes the video universally playable. Because the converter also re-encodes at a sensible bitrate, the MP4 is usually smaller than the MOV.

Private by design

ShrinkVid never uploads your files. The page loads once, then all decoding and encoding happens on your device using the browser’s built-in WebCodecs API (hardware-accelerated video) and WebAssembly image codecs. That makes it safe for personal, confidential or work files — and there is no queue, no file size cap and no watermark. Read how it works.

Frequently asked questions

Are my files uploaded to a server?

No. ShrinkVid runs entirely in your browser. Files are read and encoded on your own device with WebCodecs and WebAssembly, so nothing is uploaded, stored or seen by anyone else. You can even disconnect from the internet after the page loads and it keeps working.

Is the conversion lossless?

No — the video is re-encoded to H.264. With High quality at original resolution the difference is very hard to see.

Is it really free? Is there a watermark or file size limit?

It is completely free with no watermark, no sign-up and no server-side file size limit. Because processing happens on your device, the only practical limits are your device’s memory and speed.
