Trim PDF Margins for a Cleaner Document
Scans and exports often carry oversized margins, stray edges or uneven borders. Crop a PDF to trim them away and the page looks deliberate instead of accidental. Reframe a single page or crop them all at once — the text and images you keep stay perfectly sharp, because cropping only changes what is shown, not the quality of what is inside.
