About
Flat-looking GIFs with muted colors often just need a contrast boost to look punchy again. On the flip side, high-contrast GIFs can look harsh and lose shadow detail. This tool gives you a slider to push contrast up or pull it down across every frame, helping you get the exact visual tone you're after.
Features
Increase or decrease contrast with a single slider — changes apply to every frame
Real-time preview so you can see the effect before downloading
Doesn't alter frame timing, resolution, or transparency
Fully client-side processing keeps your files private

Pro Tips
A small contrast boost (10-15%) can make a flat GIF look noticeably sharper without looking overprocessed
Lowering contrast is handy for creating a faded, vintage-style look on animations
For the best results, adjust contrast first, then fine-tune brightness if needed — doing it in that order avoids clipping
