Honest codec handling
MOV is a container, not a codec: H.264 inside converts everywhere, while ProRes and Animation codec files cannot be decoded by any browser. The tool tells you which case you are in, immediately.

Your file is read, transformed and re-encoded inside this browser tab using JavaScript. There is no upload endpoint — nothing leaves your machine, nothing is stored, and the result is created as a local object URL that disappears when you close the page.
Overview
About the MOV to GIF
Convert MOV video to GIF free online when the clip uses a browser-playable codec such as H.264. Sampling happens locally; unplayable codecs are reported honestly.
MOV is QuickTime's container and the default of macOS screen recording, older iPhone video and a great deal of camera footage. Whether it converts anywhere depends entirely on the codec inside the wrapper — so this page is upfront about both outcomes.
The two kinds of MOV
- H.264 inside MOV — phone clips, macOS screen recordings, most consumer sources. These decode in every modern browser and sample into GIF exactly like MP4 files do.
- ProRes, Animation or HEVC inside MOV — professional camera and edit-suite exports. No browser ships these decoders, so no browser tool can sample them. The upload is refused with that explanation rather than a silent failure.
Making the loop worth sharing
Isolate the moment with the start and stop fields before adjusting anything else; three to six seconds is the range that reads as a loop rather than a clip. Then width — 480 px for legibility, 320 px for chat — and finally frame rate, where 8–10 fps covers almost everything people loop.
If your file is refused
Re-export from the source app as H.264 (QuickTime's “Export As” menu, or any editor's MP4 preset). The conversion then succeeds unchanged, and the re-exported file is also the one every other web tool will accept.
Step by step
How to use the MOV to GIF
Drop a .mov file onto the upload area; playable clips report duration and resolution immediately.
Set the start and stop seconds around the moment you want to loop.
Choose a frame rate and output width, then press Convert to GIF.
If the clip's codec is not browser-playable you will see a clear explanation instead of a spinner.
Why use it
Benefits and common use cases
What this tool is good for, and what it deliberately does not try to do.
iPhone and Mac clips welcome
QuickTime MOV is what macOS screen recording and older iPhone video produce. The H.264 majority of those files samples here exactly like MP4 does.
No upload, no transcode queue
Sampling runs against a local object URL through your browser's decoder. A 100 MB clip stays on your disk the whole time.
Questions
Frequently asked questions
Short, honest answers about quality, limits and privacy.
My MOV file will not convert. Why?
MOV files from professional cameras and Final Cut exports often carry ProRes or Apple Animation codec, which no browser ships a decoder for. The file plays in QuickTime but not on the web. Re-exporting as H.264 MP4 or MOV makes it convertible.
Is MOV different from MP4 for this tool?
Only in the container wrapper. When both carry H.264 video — the common case for phone and screen recordings — the sampling path is identical and results match frame for frame.
What is the longest clip I can convert?
The sampled span is capped at 20 seconds and 90 frames, whichever binds first. Use the start and stop fields to place that window exactly where the moment is.
