How to use
Pixels with alpha above the threshold define the smallest bounding rectangle. Run the tool to crop to that rectangle.
Limits and behavior
A fully transparent image produces an error. This removes transparent borders, not white or other solid-color margins. Still PNG, JPEG and WebP only, up to 20 MB, 4 megapixels and 4,096 pixels per side. Animated PNG/WebP are rejected. Processing and downloads stay on your device. Browser decoding applies EXIF orientation; exports do not preserve EXIF, DPI or original color-profile metadata. PNG preserves transparency; JPEG flattens it onto white. WebP export requires a browser encoder and is checked before download.
Remove invisible transparent margins
Crop away outer rows and columns with no visible pixels. This transparent-border remover is useful for logos, stickers and assets with unwanted empty space.
Will it remove solid white backgrounds?
No. Opaque white pixels are not transparent and are not treated as empty space by an alpha-based trimmer.
