So you want to perfectly crop the document without damaging the graphics or transparency mask?
Meet Trim. She’ll be your official haircutter. She can trim away blank areas on top, bottom, left or right. The image isn’t transparency? No problem, she has experiences in trimming away plain color. Textured background, on the other hand, is out of her résumé.
1. Choose Image > Trim
2. In the Trim dialog box, choose either:
• Top Left / Bottom Right Pixel Color: If there is a background image in any of the colors, use this one. Top Left / Bottom Right are options to let you decide which corner to use as a start point for trimming
3. If you don’t want to trim one or more of the sides, unselect the checkboxes in Trim Away.
Your document is now perfectly cropped up. No more wasted space and file size
