How it works

Three steps. No upload, no signup.

  1. 1

    Drop your file

    Click the dropzone above or drag a MOV from your desktop. Files of any size, there's no upload, so there's no upload limit.

  2. 2

    Convert in your browser

    The conversion runs entirely in this tab using JavaScript and WebAssembly. Your file never touches our servers, we don't have any.

  3. 3

    Download

    Get your GIF the moment the conversion finishes. Convert another, or close the tab.

Files stay on your device

Your file is never uploaded. The entire conversion runs in your browser using WebAssembly. We can't see what you convert because we have no server to see it.

No file size limit

Server converters cap free users at 1-2 GB and gate larger files behind a paid plan. Since nothing uploads, our limit is whatever your browser can handle.

Free, no signup, no ads on conversions

No account required. No watermark on the output. No queue. Drop a file, get a converted file.

Why convert MOV → GIF

What this conversion is actually for

Apple screen recordings save as .mov. Turning them into GIFs is the standard 'demo loop for a README, tweet, or Slack' workflow. Uses FFmpeg's split + palettegen + paletteuse filter chain in one pass, which gives visibly cleaner colors than naive single-pass quantization.

A real example

You recorded a 6-second app demo with Cmd+Shift+5 on Mac, saved as .mov. Convert here, paste the GIF into a Slack thread or a GitHub issue.

Troubleshooting

The output GIF is huge.

GIF is an inefficient format for video; even with palette optimisation, multi-second recordings can easily hit MB-size. We cap framerate at 10fps to keep things sane. For smaller demos, consider WebM or MP4 instead and host on a service that supports embedded video.

Formats involved

About MOV and GIF

MOV, QuickTime Movie

MOV is Apple's QuickTime container, used by macOS and iOS for screen recordings and the iPhone Camera app. Structurally very similar to MP4, the two formats share most of the same internal codecs (H.264, HEVC) and can usually be losslessly remuxed between each other without re-encoding. Universal compatibility, slightly favored on Apple platforms.

How to open

QuickTime Player (macOS), every modern video player. Some older Windows software may not handle the QuickTime container, converting to MP4 fixes it without quality loss.

GIF, Graphics Interchange Format

GIF dates to 1987 and is best known today for animated short clips. The format is limited to 256 colors per frame, which is why photographic GIFs look blotchy, but for low-color animations and reaction loops it's the universal compatibility format. For any animation longer than a few seconds, MP4 is dramatically smaller (often 10-20×) and every social platform converts uploaded GIFs to MP4 internally.

How to open

Every browser and OS displays GIFs inline. Windows, macOS, iOS, Android, and Linux all open them by default with no extra software.

FAQ

Common questions

Is this MOV → GIF converter really free?

Yes. No signup, no watermark, no daily file count limit. Every conversion runs in your browser, your file never touches our servers because there are no servers.

Where does my file go when I convert it?

Nowhere. The conversion runs entirely in your browser using JavaScript and WebAssembly. Your file is never uploaded to our servers. We don't have any servers handling files, there's nothing for us to log, store, or accidentally leak.

What's the maximum file size?

Whatever your browser can hold in memory. Practically, this means a few hundred MB on most computers, significantly larger than the 1-2 GB caps that server-upload converters charge for. Very large files (multi-GB) may require closing other browser tabs first.

Why convert MOV to GIF?

iPhone screen recordings, Apple ecosystem video. Short animated loops; reaction images; legacy compatibility. The most common reason to convert is compatibility, GIF works in places where MOV doesn't, or vice versa.

How do I open a MOV file in the first place?

QuickTime Player (macOS), every modern video player. Some older Windows software may not handle the QuickTime container, converting to MP4 fixes it without quality loss.

Does this work offline?

Once the page is loaded, the conversion itself runs entirely offline. The first time you use a tool, your browser downloads the conversion library (a one-time cache). If you reload while offline, the page won't load, but you can install the site as a Progressive Web App for full offline use.

Can I convert multiple files at once?

Single file at a time for now. Batch conversion is on the roadmap, for now, drop one file, download the result, then convert the next.
