Optimisation shrinks a GIF by storing it smarter — frame differencing, transparency reuse and metadata stripping — rather than by degrading it. Many GIFs from screen recorders and exporters carry easy wins.
Pick a strength preset and pixelpix runs the right gifsicle optimisation level for your file's size.
Shrink storage without changing how it looks
Optimisation is lossless-leaning: it makes a GIF smaller by storing it more cleverly — differencing frames, reusing transparency, and stripping bulky metadata — rather than by degrading the picture. Many GIFs exported from screen recorders and design tools carry easy, invisible savings.
How it works
Drop your GIF and open Optimize.
Pick a strength preset.
Apply and compare the before/after sizes.
Like every pixelpix tool, this runs 100% in your browser: your file is never uploaded to a server, never leaves your device, and works even offline once the page has loaded.
Frequently asked questions
How is Optimise different from Compress?
Optimise focuses on smarter storage with minimal visible change. Compress additionally lets you trade quality (colours, frame rate) for bigger savings. Try Optimise first if you want to keep the look identical.
Why did my GIF barely shrink?
If it was already well-optimised, there is little to gain. The tool applies the right optimisation level for the file size and will not inflate it.
Does optimising remove the animation or looping?
No. Looping is preserved; only redundant data and metadata are removed.
