Best for
Not ideal for
Very large files
Large files take longer and can hit browser memory limits — try a smaller sample first.
Skipping the output check
Compare the first rows or pages of the output with the input before using it in production.
Files from unusual exporters
Some files use format variants that do not convert cleanly — if the output looks wrong, re-save the file from the app that created it and try again.
Background
A website hero section uses a 15MB animated GIF that causes significant layout shift and slow loading.
Problem
The file is too large for optimal web performance.
How to use
Upload the GIF, select 'Medium' optimization, and enable 'Remove Metadata' to strip unnecessary data.
Outcome
The file size is reduced to under 3MB while maintaining visual clarity, significantly improving page load speed.
Background
An animated product showcase GIF exceeds the 2MB limit for a marketing email campaign.
Problem
The email service provider rejects the file due to its large size.
How to use
Upload the file, set 'Color Reduction' to 128 colors, and use 'Aggressive' optimization to hit the target size.
Outcome
The GIF is successfully compressed to 1.8MB, allowing it to be embedded in the newsletter without delivery issues.
It depends on your settings. Using 'Lossless' mode preserves original quality, while 'Aggressive' compression may slightly reduce visual fidelity to achieve smaller file sizes.
Yes, you can use the 'Target File Size' option to instruct the tool to compress the file toward your desired limit.
Dithering helps simulate colors that are not in the palette, which is useful for maintaining visual depth when reducing the total number of colors in a GIF.
No, the tool includes a 'Preserve Transparency' option to ensure your GIF's transparent background remains intact.
Yes, the tool supports GIF files up to 50MB in size.
