About
Sometimes you need to know precisely where transparency lives in your GIF — not just whether it exists, but which specific pixels are see-through. This tool highlights all transparent pixels across every frame, making it easy to spot holes, gaps, or unintended transparency that might cause problems when the GIF is displayed on different backgrounds.
Features
Clear visual highlighting makes transparent pixels impossible to miss
Frame-by-frame view lets you track transparency that changes throughout the animation
Shows both fully transparent pixels and partially transparent ones separately
Everything runs in your browser with zero uploads

Use the information to decide if you need to fill, fix, or keep the transparent areas
Pro Tips
Scattered transparent pixels often indicate a noisy background removal — you might want to clean those up
If only certain frames have transparency, the GIF might have inconsistent disposal methods between frames
Use this tool alongside the alpha mask generator to get both a pixel map and a visual mask view
