GIF to M4V converter
Turn your GIF into an M4V that plays smoothly and takes a fraction of the space. M4V is the Apple version of an MP4, and the two are close enough that converting between them is quick and costs no quality. One thing to know first: anything see-through in the GIF comes out on a solid background, white unless you choose another colour. Your file never leaves your computer.

How to convert GIF to M4V
- 1 Drop your GIF .gif file onto the page, or click to browse for it.
- 2 Pick how smooth and how sharp you want it. The defaults suit a short looping clip.
- 3 Convert. The work happens on your own machine, so how long it takes depends on your computer and the file.
- 4 Download the M4V, or add more files and do the whole set in one go.
Why convert GIF to M4V
- The same animation as an M4V is routinely a tenth of the size, plays smoothly and stops stuttering on a slow connection.
- M4V files come out much smaller, which is the difference between a page that loads straight away and one that keeps people waiting.
- You are sending this somewhere that will not keep a transparent background anyway, so putting it on a solid colour costs you nothing.
- Essentially MP4, so converting is fast and costs nothing.
- Supports chapters and multiple audio tracks in Apple players.

Quality and what changes
This is the step where information is discarded, and it cannot be undone by converting back later. M4V throws away detail the eye is least likely to notice, which is invisible at sensible settings and shows as blocking around sharp edges and text when pushed hard. Keep the GIF as your master and treat the M4V as a delivery copy.
- Anything see-through comes out on a solid background, white unless you choose another colour.
- Only the first frame of an animated GIF is kept.
- Browsers will not display an M4V, so it downloads rather than opening in a tab.
- One M4V limitation to keep in mind: non-Apple players may refuse the extension even when the file is fine.
Questions about GIF to M4V
Will I lose transparency converting GIF to M4V?
Yes. An M4V cannot hold transparency, so anything see-through comes out on a solid colour, white unless you choose another. If the transparency matters, convert to PNG or WebP instead, and only flatten once you know what the image will sit on.
What happens to an animated GIF?
M4V holds a single image, so only one frame survives, normally the first. If you need the motion, convert to a format that keeps it such as MP4, WebM or WebP rather than to M4V.
Is my GIF file uploaded anywhere?
No. The whole thing runs inside the browser tab you already have open. Your GIF is read straight from your own disk, converted on your machine and handed back as an M4V. Nothing is sent anywhere, nothing is stored and there is no account.
Is there a file size limit?
There is no server-side limit because no server sees the file. The real ceiling is your device memory, since the input and the output both have to fit in the tab. A few hundred megabytes is usually fine on a desktop machine and considerably less on a phone.
Can I convert several GIF files at once?
Yes. Add as many as you like and they are processed one after another, then offered as separate M4V downloads or as a single ZIP. Speed depends on your own processor rather than on a queue.
Does the converter work offline?
Yes, after the page has loaded once. The engine is cached by the browser, so you can disconnect, reload and keep converting. That falls out of doing the work locally rather than being a separate mode you switch on.
