How to Crop PDF Pages Online
Cropping removes the outer edges of each page. It's ideal for removing scanner borders, trimming excessive white space, or resizing a document to fit a specific format.
Understanding points
PDF dimensions use points: 1pt = 0.353mm. A standard A4 page is 595 × 842 points. Typical scanner margins are 18–54 points — start with 36 on each side and adjust.
