About
Sometimes a GIF comes out too dark to see clearly, or too bright and washed out. Instead of re-recording or re-exporting, just adjust the brightness here. You can lighten underexposed screen recordings, darken overblown outdoor clips, or tweak the mood of any animation — all without affecting the frame timing or resolution.
Features
Simple slider control to increase or decrease brightness across every frame
Real-time preview so you can see exactly what the output will look like
Frame timing, resolution, and transparency are all preserved
Runs completely in your browser — your GIF stays on your device
Guide
Upload the GIF you want to brighten or darken
Drag the brightness slider left to darken or right to brighten
Watch the preview update in real time across all frames
Download the adjusted GIF once it looks the way you want
Pro Tips
Small adjustments (10-20%) usually look the most natural — big jumps tend to wash out colors or crush shadows
If the GIF still doesn't look right after brightness alone, try pairing it with the contrast tool for a more balanced result
For screen recordings that are hard to read, a slight brightness bump plus sharpening can make a big difference
