However you searched for this — how to resize a gif, a gif size changer, or just shrink one for Discord — this is it: pick a height, the width follows the GIF's own proportions, and you get the same animation back. Free, no account, up to 400 MB.
Choose a height from the list and the width scales to match your GIF's own proportions automatically, so nothing gets stretched or squashed. The animation keeps every frame and its own timing.
Measured directly against this tool: sizes up to about 1280px wide come out exact — 480p and 720p land on the pixel. Ask for more than that (1080p, 1440p, 4K) and a file still comes back, but the colour-palette step that keeps it banding-free caps the final width at 1280px, so a wide 1080p target lands at 1280 wide instead of the full size. For an actual 1080p+ result, resize the source as a video first and turn it into a GIF after.
The output gets its own colour palette built from your GIF, not a generic web palette — that's what keeps gradients and flat colour smooth instead of banded.
This page makes the whole picture smaller or bigger. Need to cut a piece out of the frame instead? Crop GIF does that. Starting from a video rather than a GIF? Our sister site has a video to GIF maker.
Only need to cut it down to a shorter loop, or change how fast it plays? GIF cutter trims the length and GIF speed changer handles the pace — resize first if the file also needs to be smaller.
A browser can't rebuild a GIF's colour palette at a new size, so the file is uploaded to our server, resized there, and deleted the moment the job finishes — we keep no copy. Limit: 400 MB and 20 minutes of source length.
Same tool under whatever name got you here: gif resizer, resize gif online, gif file resize online, or gif size changer — type any of those into Google and pages like this one are what turns up.
It's free at any size up to the limit above: no watermark, no account, no trial.
Discord's free upload limit is 20 MB — a smaller GIF (480p instead of the original size, say) usually clears that without cropping any of the frame away. The same trick works for Slack, e-mail attachments, or a page that's too heavy.
No app needed — open this page in Safari on an iPhone or Chrome on Android, pick a size the same way you would on a laptop, and download the resized GIF.
Pick a height from the list — the width follows your GIF's own proportions automatically — then download. The animation keeps every frame.
Yes. No watermark, no account, no daily cap — up to 400 MB and 20 minutes of source length.
Pick a height; the width is calculated from your GIF's own aspect ratio, so nothing gets stretched or squashed.
You can pick those from the list and get a file back, but the colour-palette step that keeps the result banding-free caps the final width at 1280px — so a wide 1080p or 4K target comes back 1280px wide instead of the full size. For a true 1080p+ result, resize the source video first and make the GIF from that afterwards.
No — the output gets a fresh colour palette built from your own GIF rather than a generic web palette, which is what usually causes banding.
It's uploaded to our own server, resized there, and deleted the instant the job finishes. Nothing is kept or looked at.
iLoveIMG limits file size and how many images you can process per batch on its free tier. This one has no account and no daily cap up to 400 MB, and hands the animation back as a real GIF, not a flattened still.
Yes — this one. No watermark, no account, no daily cap; files up to 400 MB.
Yes — open this page in Safari or Chrome, pick a size and download the result. No app needed.
