Compress MOV Online
Reduce a MOV from an iPhone, camera, or Mac export and download an H.264 MP4 for everyday playback and sharing. The browser processes the source on your device, while the original MOV remains unchanged.
Source container
QuickTime MOV
MOV is Apple's QuickTime movie container. Its extension does not tell you which video codec or bitrate is inside.
Sharing copy
H.264 MP4
The download uses H.264 video and optional AAC audio in MP4, a combination commonly supported by browsers and devices.

Editing matters
Retain the camera or editing export if you still need its original tracks, metadata, quality, or codec-specific features.

Why a MOV can be awkward to send
QuickTime files are at home in Apple and production workflows, but MOV is a container rather than a quality level. A long phone recording, high-bitrate camera clip, or editing export may be far heavier than the version a recipient needs.
Prepare a familiar delivery format
MOV browser support depends on the codecs inside it. Re-encoding to H.264 MP4 gives a recipient a more conventional copy for a web form, chat, Windows PC, or non-Apple device.
Match size to the destination
Set a target for a storage quota or uploader, or use Advanced mode to choose Original, 1080p, 720p, or 480p plus video bitrate, audio bitrate, and frame rate.
Know what conversion changes
This is a re-encode into MP4, not a rename of the extension. Compression can discard picture detail, and the result is intended as a straightforward viewing copy.
Keep two files when the source has value
Use the MP4 for sending or uploading, but preserve the MOV for another edit, a higher-quality export, or an Apple workflow that already handles it well.
How to compress a MOV for sharing
Decide where the copy will play and how much detail that use needs before choosing a smaller target.
Add the QuickTime file
Choose the MOV or drop it into the tool. The browser reads the file locally and does not alter the source.
Set the delivery budget
Use Basic mode for a target-size estimate. A longer clip gets fewer bits per second at the same target, so leave more room for motion or fine detail.
Adjust an oversized camera clip
Try 1080p or 720p when the original dimensions exceed the viewing need. Advanced mode also lets you reduce frame rate, tune both bitrates, or remove unneeded audio.
Review the MP4 copy
Play the download on the intended device, inspect movement and sound, and confirm its measured size. Raise the target if faces, text, or action have degraded too far.
MOV compression questions
Practical answers for turning a QuickTime source into a smaller delivery file.
MOV FAQ
Is MOV a codec?
No. MOV is the QuickTime movie container, and the video inside may use different codecs. That is why two MOV files of the same duration can differ greatly in size and playback support.
MOV FAQ
Why convert MOV to MP4?
An H.264 MP4 is commonly easier to preview in browsers and exchange across phones, PCs, forms, and messaging tools. It also gives you a chance to lower bitrate or resolution for a smaller delivery copy.
MOV FAQ
When should I keep the MOV instead?
Keep it when it is your camera original, an editing master, or a file whose original tracks and metadata matter. The compressed MP4 should complement that source rather than replace it.
MOV FAQ
Does MOV compression happen on a server?
No. The selected MOV is processed locally in your browser, and the finished MP4 is downloaded on the same device.
MOV FAQ
Will the result hit my target size exactly?
Treat it as an estimate. Duration, motion, audio, and encoder behavior can shift the final size, so leave some margin below a hard upload limit and inspect the file.
