Auto Crop Empty Space (Trim Transparent Pixels)
Instantly trim away empty transparent borders around a logo or graphic. Shrink the canvas down to tightly fit the actual image content.
Clean Up Messy Assets
When you receive a logo file from a client, it often has massive, unnecessary transparent padding around it, making it impossible to align properly on a website. This tool scans the pixels of your image from the outside in, finds exactly where the transparent space ends, and automatically trims the canvas to perfectly hug the graphic.
