How to resize GIF
- Drop the animated GIF.
- Pick the width you want, in pixels.
- Press Resize and download — the height follows.
What happens to your file
gifsicle scales every frame to fit the width you name, never enlarging, re-optimises the frames against each other, and keeps the timing, the loop count and the transparency. The height follows the picture so nothing is squashed.
Scaling is also the most effective way to make a GIF smaller. A GIF stores whole frames rather than the differences a video codec stores, so its size grows with the square of the width: halving 800 pixels to 400 typically takes about three quarters of the bytes out, far more than any amount of re-compressing at the original size.
If the file is still too big after resizing, the compress GIF page drops the frame rate and the colour palette, which are the other two levers. Past a certain point the honest answer is that the thing should be a video — a fifteen-second GIF will always dwarf the same clip as MP4.
Questions
How do I resize an animated GIF without breaking the animation?
Drop it here and give a width. Every frame is scaled together and the timing, loop count and transparency are preserved, so the animation plays exactly as before at the new size.
Can I make a GIF bigger?
Not here, deliberately. Enlarging invents pixels that were never captured and a GIF’s limited palette makes the result look worse than the original did small. If you need it larger, make a new GIF from the source video at that size.
Will resizing make the file smaller?
Substantially. Because a GIF stores full frames, the bytes fall roughly with the area — halve the width and you often keep only about a quarter of the pixels. It is the single biggest saving available.
Does the number of colours change?
No. The palette is left alone here; only the dimensions change. Reducing colours is what the compress GIF page does, and it is the right next step if the size still will not fit.
What width should I use?
For a chat message or an issue thread, 400–600 pixels is usually plenty and keeps the file manageable. For a README or a documentation page, match the column width so the browser is not scaling it again.
Is it really free?
Yes — no sign-up, no watermark and no cap on how many you resize.
Do it once, not on every form
A form that wants a square JPEG under 240 KB says so on the page. The Fylane extension reads that, fits your photo to it, and puts it in the field — without you working out what 240 KB looks like.
And it keeps the result. The next application that asks for a résumé, a cover letter and a photo fills all three from one tap, each one refitted to what that site accepts.
Your files stay in the browser, encrypted, on your machine. Nothing is uploaded to keep them and nothing is sent anywhere to fill a form.
