Trim transparent pixels
Remove empty transparent space around PNG and WebP images with precise alpha detection and consistent padding.
Your images never leave this browser
Drop transparent images here
PNG or WebP, up to 100 files. Transparent edges are detected locally.
Exact alpha bounds
The tool scans the alpha channel and crops to the smallest rectangle containing visible pixels.
Adjustable threshold
Ignore nearly transparent edge pixels without changing the visible artwork itself.
Consistent padding
Add the same transparent margin outside every detected bound before export.
