MOV to GIF
MOV files come from two places, QuickTime screen recordings and iPhone cameras, and each one wants different settings. Both convert here without an upload, which matters more for MOV than for any other format because iPhone clips are enormous.
- QuickTime and iPhone MOV
- No 200 MB ceiling
- HEVC and ProRes convert
- Works in mobile Safari
- No upload over cellular
Starting the converter
One moment. The engine downloads only when you pick a file.
Your 4K iPhone clip is 150MB a minute. That is the whole point.
An iPhone recording 4K at 60fps writes roughly 400MB every two minutes. A one minute clip at 4K30 is about 190MB. Those numbers are why MOV is the format where uploading hurts most, and where the tools ranking for this search run into their own limits first.
ezgif refuses anything over 200MB. FreeConvert takes 1GB then asks for money. TinyWow and CloudConvert both meter the free tier. And before any of those caps even applies, you are sitting through an upload of a file that is already on the device you are reading this on. Here the page reads the clip from disk, the copy of ffmpeg running in this tab decodes it and writes the GIF, and none of it touches the network.
GIF still too big? Long camera clips make big GIFs even at 480px. Drop the finished file into the GIF compressor and pull it under a Discord, Slack or email limit without re-encoding from the source.
The HEVC caveat, stated plainly
Since iOS 11, iPhones record in HEVC by default. The container is still .mov, so the file looks identical in Finder, but the video inside is H.265 rather than H.264. Browser support for playing H.265 is uneven and always has been.
That affects one thing only: whether you get a preview. The conversion does not go through your browser's decoders. It goes through ffmpeg compiled to WebAssembly, which brings its own, so the table below is a table about the preview pane and nothing else. Where it says no preview, you get a placeholder and a working converter.
| Where you are | H.264 .mov preview | HEVC .mov preview |
|---|---|---|
| iPhone or iPad, Safari | Works | Works |
| Mac, any browser | Works | Works |
| Windows, Chrome or Edge | Works | Only with the HEVC extension installed |
| Linux or Android | Works | Usually not |
So if a MOV loads but the preview pane says the format cannot be previewed, this is what happened. It is not a corrupt file, it is not a size problem, and it is not a reason to go and find another tool. Press convert. If you would rather have the preview back, switch the camera to Most Compatible in Settings, Camera, Formats so it records H.264 from then on, or work on the Apple device the clip came from, where HEVC plays everywhere.
Screen recordings want different settings from camera footage
A QuickTime screen recording is flat colour, hard edges and long stretches where nothing moves. Camera footage is noise, gradients and constant change. The same defaults cannot serve both, which is why this page starts at 192 colours and 12fps rather than the general defaults.
- Screen recording. 128 to 256 colours, 10 to 12fps, dithering off or off, width 640 to 960 so text stays readable. Text is the thing that breaks first, and it breaks on width, not on colour count.
- Camera footage. 96 to 160 colours, 15 to 20fps, Sierra2 4a dithering, width 480. Skin tones and skies band without dithering, and sensor noise makes the palette work far harder than it needs to.
- ProRes from a camera. Drop it straight in. No preview, because no browser plays ProRes, and it is the slowest source we have measured at about forty percent longer than the same clip as H.264. Both of those are still fine.
Looking for GIF to MOV instead?
You are not alone, and the search results know it. Several of the pages ranking for MOV to GIF are actually GIF to MOV pages, which happens when a search has two opposite intents and no page serves either one well. Going from GIF to MOV means encoding video, not writing a palette, so it is a different tool rather than a different setting on this one. It is on the list rather than hidden behind a broken button.
MOV to GIF questions
Why will my iPhone MOV not preview?
Almost always HEVC. In High Efficiency mode an iPhone records H.265 inside a .mov container, and only Apple hardware, plus Windows machines with the HEVC extension installed, will play that in a browser. What it stops is the preview, not the conversion. The converter is ffmpeg compiled to WebAssembly and it carries its own H.265 decoder rather than borrowing the browser's, so the panel shows a placeholder where the video would be and the trim handles still work, driven by the length read out of the file. Dropped through Chromium 147 on Windows, a four second 720p HEVC .mov showed no preview and converted in 1.5 seconds.
My MOV is 900MB. Is that a problem?
Not here, because it is never uploaded. A 4K 60fps iPhone clip runs about 150MB per minute, which is exactly the size that hits the 200MB ceiling on ezgif and burns through a FreeConvert free tier. The practical limit in this tab is your own memory, and trimming to the seconds you want before converting keeps you well clear of it.
Will a ProRes MOV work?
Yes, and this page used to say the opposite, which was wrong. No browser will play ProRes, so the preview pane shows a placeholder, but the ProRes decoder ships inside the converter along with everything else ffmpeg supports. Measured on Chromium 147 on Windows: a four second 720p ProRes 422 HQ file of 22.6MB became a 796KB GIF in 1.8 seconds, against 1.3 seconds for the same clip as H.264. It is the slowest source we have measured and it is still under two seconds.
What settings suit a QuickTime screen recording?
Higher colour count, lower frame rate. Screen content is flat, so 128 to 256 colours stay clean while dithering only adds noise, and 10 to 12fps reads fine because a cursor and a menu do not need smooth motion. Turn dithering off: on flat screen content Bayer measured roughly double the size of no dithering at all. Those two changes typically halve the file compared with the video defaults.
Does the GIF keep the audio from the MOV?
No. GIF has no audio track. If you are recording a walkthrough where the narration matters, keep it as a video file. A muted MP4 plays like a GIF in Slack, Discord and X at a fraction of the size.
Can I convert a MOV to GIF on my iPhone directly?
Yes. This page works in mobile Safari, and because the clip never leaves the phone you are not pushing 150MB over cellular to a server. Trim before converting so the tab does not run out of memory. There is a full iPhone walkthrough on its own page.
I actually want GIF to MOV. Is that here?
Not yet. Half the results for this search are GIF to MOV pages, which is a strong hint that the search itself is muddled. Going the other way needs a video encoder rather than a GIF encoder, and it is on the list. For now, any tool that accepts a GIF as video input will do it.
