Trim the margins off every page of a PDF. Nothing is uploaded.
You type how much to take off the top, right, bottom and left, in millimetres or inches. The numbers are measured on the page as you see it, so the top is the top even when the page is stored sideways. The chips fill all four sides at once: none, 5 mm, 10 mm or 0.5 in. A side can be 0, and each side can be at most 1763 mm (69 in). Commas count as decimal marks, so 2,5 is 2.5. The thumbnails shade the strips that will go, on the first six pages, and the line above the button gives the size of the first chosen page before and after, for example 210 × 297 mm to 190 × 277 mm. If the margins would leave a page with less than a quarter of an inch (6.35 mm) in either direction, the tool names that page and does not run.
The tool sets each chosen page's CropBox, the rectangle that viewers show, and leaves the MediaBox, the full sheet, exactly as it was. Chrome, Acrobat, Preview and most other readers display and print only the CropBox. The text and pictures outside it are still in the file. Someone who opens the PDF in a program that ignores the CropBox, or who searches for a word or selects all the text, can still reach them, and the file is not any smaller. If the cropped-away part is confidential, run the result through Compress PDF, which rebuilds every page as a picture, so only what is visible remains. Nothing else about the file is touched: links, bookmarks and form fields stay where they were.
A page marked as rotated by 90, 180 or 270 degrees is cropped from the edges you see, so a landscape scan that is stored sideways loses its visible top, not its stored left edge. A page that already has a CropBox is cropped from that box, and a CropBox that sticks out past the MediaBox is first clipped to the sheet. Crop a file twice and the second pass trims the first result further. Pages with different sizes each get the same margins, so a 100 mm margin that suits an A4 page might be too much for an A6 insert. The tool checks every chosen page before it changes any, and stops with the page number if one cannot take the margins.
Leave Apply to blank to crop every page, or type ranges such as 1-3, 7, 9-. Pages outside the range are left exactly as they were, and a range that is out of order or past the last page is reported before anything runs. There is no dragging on the page: the margins are numbers. The same margins apply to every chosen page, so it cannot trim each page to its own content automatically. The PDF is read and written in this tab and is never uploaded. A password-protected PDF is refused, because this tool does not remove passwords. The tool asks before opening a file over 200 MB or with more than 1000 pages.
No. The tool hides it by setting the CropBox. The text and pictures stay in the file, and searching or selecting all can still find them. To remove them for real, run the cropped file through Compress PDF, which rebuilds every page as a picture.
Type the pages in Apply to, such as 1-3, 7 or 5-. Those pages are cropped and every other page is copied unchanged. A 10-page PDF with 2-4 typed gets 3 cropped pages and 7 left as they were.
Because the cropped-away part is still stored. Only the visible rectangle changes. If the size matters, Compress PDF builds a smaller copy, and it also drops what was outside the crop.
Start with 10 mm on every side for a typical A4 or Letter scan, then check the grey strips on the thumbnails. A 0.5 in margin takes off 12.7 mm. If the scan is skewed, use a smaller margin so the text is not clipped.
A page must keep at least a quarter of an inch (6.35 mm) in width and height. On a 100 mm wide page, left and right margins of 50 mm each leave nothing, so the tool names the page and stops. Lower the margins or crop only the larger pages.
Yes. Margins are measured on the page as displayed. A page stored with a 90 degree rotation, such as a landscape scan, loses the strip you see at the top when you set a top margin.
