Crop PDF
Crop the margins or trim a PDF to just the area you want. Tell Happycapy what to remove — white borders, headers, or everything outside a region — and it applies the crop across one page or the whole document while keeping the text sharp. Free to start.
How to crop PDF pages
Define the area to keep and remove unwanted margins, marks, or edges from selected pages.
Describe the crop
Pick an example or say what to trim — white margins, headers, or everything outside a region.
Attach your PDF
Continue into Happycapy and drop in your file — one PDF or a whole folder.
Let Happycapy crop
It adjusts the visible page area across the pages you choose, keeping the content sharp.
Download your PDF
Review and download a tightly cropped PDF, ready to share or print.
Who crops PDFs
Useful for scanned documents, slide exports, handouts, and files with oversized margins.
Students and researchers
Trim wide margins off papers and scans so the content fills the page for reading or printing.
Office workers
Cut headers, footers, or stamps from documents before sharing a cleaner version.
Anyone fixing scans
Remove the black borders and uneven edges that scanners add around a page.
Tips for accurate PDF cropping
Page range, crop box, margins, and whether pages share the same layout determine the result.
Name what to keep or cut
"keep the center" or "trim 2cm margins" — be specific about the area.
All pages or one
Apply the crop to the whole PDF or just a page or range.
Great for scans
Ask to remove black scan borders for a clean, printable page.
Uniform vs per-page
Use one crop box for all pages, or different crops where layouts differ.
Content stays sharp
Cropping changes the view area only — text inside stays full quality.
Batch a folder
Crop many PDFs the same way in one instruction.
What to expect from PDF cropping
Review output quality, follow-up checks, and download expectations for PDF cropping.
Cropping adjusts the PDF's visible page boundaries (MediaBox/CropBox), so file size typically changes very little — usually 0–15% smaller, since content outside the crop is hidden but not deleted. Most crops complete in under 10 seconds for documents up to 100 pages. Best input: a PDF plus clear crop intent, such as remove scanner borders, trim white margins, crop all pages the same way, or crop only selected pages.
Example: Input: a scanned worksheet PDF with large scanner-bed borders and a dark edge on the left side. Output: the same pages cropped to the document area, with excess margins removed and text easier to read. Good for cleaning scans before printing, emailing, or OCR.
Cropping limits to know
Review this section when source details involve: Page range, crop box, margins, and whether pages share the same layout determine the result.
- File size barely shrinks because PDF cropping hides content outside the crop box rather than deleting it — the original data remains embedded, so storage savings are minimal.
- Scanned PDFs with uneven or skewed borders may produce inconsistent crops if white-space detection misjudges the content boundary, requiring manual adjustment.
- Cropping cannot remove headers or footers that are part of a scanned image layer — it can only trim the page boundary, not erase text or graphics within the kept region.
Frequently asked questions
How do I crop a PDF without paying?
Upload your PDF and describe what to remove — for example, 'cut 15 mm from all four margins' or 'strip the white borders' — and you'll get a cropped file back at no cost. The tool is free to start with no account required.
Can I crop every page at once or just a specific range?
Both options work. A single instruction like 'crop all pages' applies the same trim across the entire document, while specifying 'pages 3–7 only' limits the crop to that range. You can also mix: crop the body pages uniformly and leave the cover untouched.
Will cropping blur or degrade text inside the kept area?
No — cropping adjusts the PDF's media box (the boundary that defines what's visible), so the text, fonts, and images within the kept region remain at their original resolution. Only the trimmed-away area disappears.
Can I remove the black borders that appear on scanned PDFs?
Yes, and this is one of the most common uses of this tool. Describe the borders — 'remove the dark 8 px edges from every page' — and the crop is applied uniformly across scanned pages, leaving the document content intact.
Can I crop to an exact pixel, point, or millimeter measurement?
Yes. PDF coordinates are measured in points (1 pt ≈ 0.35 mm), and you can specify your target region in points, millimetres, or inches — whichever is natural for your workflow. The more precise your description, the tighter the result.
Can I batch-crop multiple PDF files in one go?
Yes. Pass several files together and describe the shared crop rule — such as 'remove 20 mm from the top of every file' — and each PDF gets its own cropped output in a single pass, rather than processing them one by one.
Do I need to install anything to use this tool?
Nothing to install — the crop engine runs entirely in your browser session. You upload the PDF, describe the trim, and download the result without touching any desktop software or browser extensions.
