About Reduce GIF Size
Learn how the browser-based GIF resizing and compression tool works, including local processing, frame timing and quality tradeoffs.
A practical tool for GIF creators
Reduce GIF Size is a browser-based tool for resizing and compressing animated GIFs. It is designed for Korean users and creators around the world who need to fit media into a display area or upload requirement without installing a separate application.
GIF files are read and processed in your browser rather than sent to a processing server. The website can make separate requests for analytics, fonts and other page resources. These website requests are distinct from GIF decoding and encoding.
Dimensions, palettes and frame timing
The processing path uses browser Canvas operations and JavaScript libraries. Palette quantization reduces the available colors; dithering offers another way to represent color gradients. Compare actual encoded output because these changes can affect both quality and bytes.
Frame skipping combines the skipped delays into retained frames, while trimming, speed settings and delay rounding can also change the result. Preserving duration does not guarantee unchanged motion. Keep the original and check downloaded output.
Presets are starting settings
Platform presets help choose initial dimensions, colors, frames and target sizes. They are not proof of current official restrictions. Read the destination’s actual attachment instructions and verify whether the saved result meets them.
Target compression compares real candidate byte counts and can report that the target was not reached. Large animations are subject to browser memory limits and the implementation’s decoded-frame protection budget.
Free use and advertising
The resizing and compression workflow is available without a watermark. The site may display third-party advertisements to support operation. Advertising should be separated from the editing workspace and should not imitate download controls or force users through waiting screens.
The project’s stated advertising policy excludes intrusive pop-ups and misleading download buttons and calls for adherence to Google publisher policies. External advertisements and linked services have their own terms and privacy practices.
