What this tool does
- You draw the frame on the page, looking at it, rather than filling in “left margin: 24 mm”.
- The frame is kept as fractions of the page size: a file made of four documents in A4, Letter and A3 crops the same way throughout.
- You can crop only the pages you tick: a mixed file often has three pages to reframe and the rest to leave alone.
- The media box is untouched: the paper size announced to the printer stays the document's own.
- A guard refuses a frame that would leave no page at all: a slip of the hand does not produce a document the size of a stamp.
What it does not do: Cropping frames, it does not erase. A PDF page carries a crop box, and readers only display what it delimits, but whatever sticks out stays in the file, and any editor can restore the box to its original size. If what sticks out has to disappear for good, “redact” is the tool you want, or a conversion to images, which flattens the page.
Nothing is uploaded. Cut your network connection once this page has loaded: the tool keeps working. How to check it yourself.
The other tools
- Merge PDFs: Several files, one document, in the order you decide.
- Organize pages: Reorder, rotate, delete, duplicate: the whole plan.
- Extract pages: Pick pages, take them out into a document of their own.
- Delete pages: Remove pages while looking at them; they are not left under the file you get.
