Questions
Will the PDF be uploaded?
No. The pages are drawn and cropped inside your browser. The file never leaves your device.
Does cropping delete what is outside the frame?
No. Cropping sets the visible area of the page, so the part outside the frame is hidden, not removed from the file. Viewers and printers show only the cropped area. To remove content for good, use a redaction tool.
How does auto-trim decide what to keep?
It looks at a small picture of each page and keeps everything darker than near-white, then leaves a border of 2% of the page. A page with a light grey background or a faint scan may keep more than you expect; set the margins by hand then.
Why are the sizes in mm and inches?
PDF pages are measured in points, 72 to the inch. The page size is shown in millimetres and inches, the units most printers and forms use.
