Is my GIF stored on your server?

No. Your file is processed in a temporary location and deleted immediately after the compressed version is sent back to you. Nothing is stored, logged, or retained.

How much can gifsicle reduce a GIF file size?

Lossless optimisation alone typically saves 10–30%. Adding lossy compression at the Balanced level usually saves 40–70% with barely visible quality loss. Results depend on the content — flat-color animations compress more than photographic ones.

What is the difference between Lossless and Balanced compression?

Lossless mode only rewrites LZW codes more efficiently — pixel colours are unchanged. Balanced and above use lossy compression, which introduces slight colour dithering in exchange for significantly smaller files. For most GIFs the difference is invisible at Balanced.

Can I compress multiple GIFs at once?

Yes — drop or select multiple GIF files at once. Each is uploaded and processed independently one after another using the same compression level.

Why Use gifsicle for GIF Compression?

Most in-browser GIF compressors work by fully decoding and re-encoding every frame, which causes generation loss and colour degradation. This tool instead uses gifsicle — the industry-standard GIF optimiser — which rewrites LZW codes at the byte level without unnecessarily destroying colour data. The result is dramatically smaller files with far better visual quality.

Compression Level Reference

Level	gifsicle flag	Best for
Lossless	`-O3` only	Archiving, when quality must be perfect
Light	`--lossy=40`	Photos, complex gradients, subtle animations
Balanced	`--lossy=80`	Most animated GIFs — good quality/size tradeoff
Maximum	`--lossy=160`	Simple flat-color animations where small size matters most

How It Works

Your GIF is uploaded over HTTPS, processed by gifsicle with -O3 (maximum LZW optimisation) and the chosen lossy level, then streamed back to you as a download. The file is deleted from the server immediately — nothing is stored or logged.
