Convert a video to GIF

Making a GIF from a video without ending up with a 40 MB file

The conversion itself is easy; keeping the result usable is the actual skill. GIF stores every frame as a complete image with at most 256 colours and no modern compression, so a video clip that weighs two megabytes as an MP4 can become forty as a GIF. Three dials control that: how many seconds, how many frames per second, and how many pixels wide. They multiply together, which is why changing one a little does more than you expect and why a 15-second cap exists at all. Understanding how they trade against each other is the difference between a GIF that sends and one that sits in a chat window forever.

Length is the most expensive dial, resolution the cheapest to cut

Because size grows with frames multiplied by pixels, halving the width removes roughly three quarters of the data while halving the duration removes only half. Cutting the picture size is therefore the most efficient saving available, and it is usually the least noticed: a GIF is watched small, in a chat bubble or beside a paragraph of text, not full screen. Reach for the width first, the frame rate second and the duration last, because duration is normally the one carrying your meaning. And be ruthless about the segment: almost every clip has a second of nothing at the start and another at the end, and trimming those costs you nothing at all.

Frame rate: smoothness you can actually see

Video runs at 25 or 30 frames per second, but a GIF does not need anywhere near that. Around 10 to 15 frames per second reads as smooth for most content, and 8 is perfectly acceptable for a slow gesture or a screen recording. Going from 25 to 12 halves the file at a cost most viewers will never notice. Fast motion is the exception: a hand waving quickly or a fast pan will look choppy at low rates, and there the honest answer is often that the clip wants to stay a video. There is also a floor imposed by the format — GIF timing is stored in hundredths of a second, so very high frame rates cannot be represented precisely and browsers quietly clamp the fastest ones anyway.

Why photographic footage suffers and screen recordings do not

The 256-colour limit is where GIF shows its age. A screen recording, a cartoon, a diagram or anything with flat areas of colour survives it beautifully, because there were never many distinct colours to begin with. Camera footage of a face, a sky or a sunset does not: those are smooth gradients made of thousands of shades, and squeezing them into 256 produces visible banding and speckled dithering. If your source is real-world video and the result looks blotchy, no setting on this page will fix it — that is the format, not the conversion. Cropping tighter helps a little, because a smaller area of the frame contains fewer distinct colours.

Where the GIF is going decides how you make it

For a website or a document, make it as good as it needs to look and stop worrying — every browser plays every GIF, transparency included. For a chat app the rules are different and worth knowing before you spend effort. Our own field testing found that a GIF made on a phone plays reliably when sent straight into a WhatsApp chat, while the identical file sent from a computer arrives frozen as a still image. So if the destination is a chat, do the conversion on the phone. The workaround from a computer is to send it as a document or file attachment rather than as a photo, which preserves the animation but shows up as an attachment rather than playing inline.

When a GIF is the wrong answer

It is worth saying plainly, because it saves people a lot of frustration. If your clip has sound, GIF cannot carry it — the format has no audio channel and never will. If it runs beyond a handful of seconds, or it is camera footage where quality matters, a video file will be smaller, sharper and smoother than any GIF of the same content. Choose GIF for what it is uniquely good at: something short that plays by itself, everywhere, without a player, a codec or anyone pressing anything. That autoplay-anywhere property is the entire reason a format this old and this inefficient is still in daily use.

Why there's a 15-second cap

GIF stores every frame as a full 256-colour image with no modern compression, so file size grows brutally fast: a 15-second clip at 10 fps is already 150 frames. For anything longer, an actual video file is both smaller and sharper — GIFs shine for short loops, reactions and demos. The free tier renders up to 5 seconds; a day pass or unlock opens the full 15.
