How to use Reduce GIF File Size
- 1. Load the GIF that is too big. Drop the oversized animation onto the page. Its current dimensions and weight set the baseline, and everything that follows happens locally in your browser.
- 2. Pull down the Scale slider. Scale (%) resizes every frame. Pixel dimensions are the dominant cost in a GIF, so dropping to 70% roughly halves the pixel data. Go as low as the destination's display size allows before touching anything else.
- 3. Cap the palette with Max colors. The Max colors slider limits how many colors each frame may use. After scaling, this is the second-best lever: 128 is usually invisible, 64 works for most screen content, and lower values start to show banding.
- 4. Check the savings and download. The preview shows the compressed animation alongside its new byte size. When quality and weight balance out, save the smaller file.
When to use Reduce GIF File Size
Reduce GIF File Size combines the two compression levers that matter most, downscaling and palette capping, into one purpose-built shrinker. Instead of learning which knob does what, you trade a little size and color for a file that actually fits where it is going: an upload form, a chat message or a page-weight budget.
- Attaching a repro to an issue tracker. GitHub caps attachments at 10 MB and your screen recording is 24 MB. Scaling to 60% and capping colors at 96 typically brings such a clip under the limit in one pass.
- Hitting an ad or CMS weight budget. An ad network or corporate CMS enforces a hard 1 MB media limit. Working the two sliders against the live size readout lets you land just under the number without guesswork.
- Making mobile pages tolerable. Analytics show your tutorial page transferring 40 MB of GIFs to phones. Shrinking each embed at the source fixes the experience without swapping the format or the CMS.
- Sending clips over slow connections. A teammate on a metered connection needs to see a UI bug now. A quick size reduction turns a multi-minute upload into seconds on both ends.

About the Reduce GIF File Size tool
Reduce GIF File Size runs as plain JavaScript in your browser tab, with no server behind it. Make a GIF smaller by scaling it down and reducing its colors. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's GIF Tools section, 110 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with 2 settings, including Scale (%) and Max colors, and the result refreshes the moment you change one. The finished file is put together in browser memory and saved with the Download button, so it never touches a server on the way to your disk. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.

No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
