Does resizing a GIF keep the animation?

Yes. ReduceGIF scales every frame to the new dimensions so timing and looping stay intact. You get a smaller or larger animated GIF, not a still.

What is the difference between resize and crop?

Resize scales the whole frame. Crop cuts a region without changing the density of the remaining pixels. Use resize for display size; use crop to reframe.

Should I compress after resizing?

Often yes if you still need a smaller file for chat or email. Dimensions first, then compress on the ReduceGIF homepage.

How to Resize a GIF Online

To resize a GIF online, scale every frame to a new width and height so the loop still plays at the size you need. On ReduceGIF, the free GIF resizer does this in your browser—by percentage or max width—without uploading your file for processing.

When you should resize (not only compress)

Compression keeps pixel dimensions the same. Resize when:

The GIF is wider than the layout (blog, chat, email)
Mobile users should not download desktop-sized frames
A platform soft-limits dimensions as well as bytes

Scaling both axes by 50% leaves about 25% of the pixels per frame (0.5 × 0.5). That geometric drop often beats lossy compression on an oversized original.

Step-by-step

Open the resizer at /resize/.
Upload your animated GIF.
Choose scale or custom width — match where the GIF will display.
Preview the animation at the new size.
Download the resized GIF.
Optional: compress if you still need a smaller file for a hard byte limit.

Resize Your GIF

Picking a target width

Think about the destination, not the export canvas:

Inline blog or docs: often a few hundred pixels wide
Chat and messaging: modest widths; see compress for Discord
Hero or product demo: size to the design breakpoint, then compress if needed

If you need explicit control over both axes and aspect-ratio behavior, see change GIF width and height.

Resize vs crop vs compress

Goal	Tool
Same composition, different pixel size	Resize
Different framing / cut edges	Crop
Same size, smaller file encoding	Compress
Stills from the loop	Extract frames

Practical order: crop (if framing is wrong) → resize → compress.

Quality and pitfalls

Upscaling. Enlarging a small GIF cannot invent detail. Prefer exporting larger from the source app when you need more pixels.

Uneven scaling. Keep aspect ratio unless you intentionally want distortion. This resizer is built for proportional scaling / width caps.

Very long, high-resolution clips. Browser memory is finite. Shorten the GIF or use a machine with more RAM if the tab struggles.

After you resize

Embed at matching CSS sizes so the browser does not scale wastefully again.
Reverse or extract frames from the resized file if those are next—working smaller is faster.
For encoding tips, see compress without losing too much quality.

Troubleshooting

File still huge — add compression; or crop empty margins.
Looks blurry — possible upscale, or CSS stretching a small file.
Tool error — try a smaller source or re-export a valid GIF.
