FAQ
Can each page crop differently?+
Currently the same crop applies to all pages. For per-page cropping, use [PDF Page Extract] to split, crop separately, then merge.
Is the trimmed area really gone?+
The PDF CropBox metadata changes, shrinking the visible area. Some viewers can re-expand it — for a permanent crop, use [PDF → Image] then convert back.
Why millimeters?+
It's the print-shop standard in Korea and Europe. Convert from inches with 1 inch = 25.4 mm.
I cropped too much.+
The original is untouched — re-upload and try a smaller value. 5–15mm is a safe range.
