Trim the dead space your PDF doesn't need
Scanned pages with huge white borders, slides with wasted margins — crop them all at once, without touching the content itself.
Scanners and phone-camera scanning apps almost never crop tight to the actual page content — you end up with wide white borders on every side, sometimes a strip of the desk the document was scanned on. Presentation exports and old templates carry the same problem in the other direction, with unused margin baked into every slide. Cropping fixes this after the fact, on the whole file at once, instead of you trimming each page individually in an image editor.
Set how much to trim from the top, bottom, left, and right in millimeters, and the same crop applies to every page in the document. The underlying content isn't re-rendered or compressed — only the visible page boundary changes, so text and images stay exactly as sharp as they were.
Check one sample page before committing
Open your PDF at 100% zoom first and estimate the white border in millimeters using a ruler on screen, or just start with a small value like 5mm and increase it after checking the result — it's faster to nudge the number up than to undo an over-aggressive crop.
Content fills the page
Removing wasted white space makes scanned documents and slide exports look intentional rather than sloppy when shared or printed.
Every page at once
Set the margin values once and they apply uniformly across the whole document — no cropping page by page in a slower editor.
No quality loss
Cropping only adjusts the visible boundary — the underlying text and images aren't recompressed or re-rendered.
Safety built in
If a margin value would cut into actual content, that page is automatically left uncropped rather than losing part of the page.
Scanned documents
Phone-scanned receipts, forms, and contracts that come with an inch of desk or table visible around the actual page.
Old presentation exports
Slide decks exported to PDF years ago with a wide unused margin baked into the template.
Printed forms re-digitized
Government or bank forms scanned at an office scanner that defaults to full-page capture regardless of content size.
Ebook and article PDFs
Downloaded PDFs with publisher margins that waste screen space when reading on a phone or tablet.
| Source | Typical white border | Suggested starting crop |
|---|---|---|
| Phone-scanned document | 15–30mm | 10mm, then adjust |
| Flatbed scanner (A4) | 10–20mm | 8mm, then adjust |
| Slide deck export | 5–15mm | 5mm, then adjust |
| Published ebook/article PDF | 10–25mm | 10mm, then adjust |
These are starting points, not fixed rules — actual margins vary by document, so check the result after the first crop and adjust before finalizing.

-
3Click "Crop PDF" The margins are removed from every page at once, with a safety check that skips any page where the crop would remove actual content.

💡 Tips
- Start with small values like 5-10mm and check the result before cropping more aggressively
- The crop applies equally to every page in the PDF, so pick a value that works for the whole document
- If unsure of exact margins, a scanned A4 page usually has 10-20mm of white border on each side
- Your file is automatically deleted from our server after processing
Is this tool free?
Yes, completely free. No signup, no watermark, no hidden charges.
Does cropping reduce quality?
No, cropping only changes the visible page boundary — the content quality stays exactly the same, since the underlying page data isn't recompressed.
Can I crop different margins per page?
This tool applies the same margins to every page in one pass. For page-specific cropping, crop the file in separate batches and re-merge the sections.
What if I enter too large a margin?
If the crop would leave less than 10 points of content on a page, that page is left uncropped automatically to avoid losing content.
Will cropping remove the header or footer text?
Only if that text sits within the margin you specify. Check a sample page's layout before applying a large crop, since headers and footers usually sit close to the top and bottom edges.
Can I undo a crop after downloading?
Not directly — cropping isn't reversible on the downloaded file. Keep your original PDF until you're happy with the cropped result, and re-crop from the original if you need different margins.
