Scanned documents and exported slides often arrive with huge white borders that waste space and look unprofessional. To crop pdf pages is to trim those margins — or cut the page down to exactly the content you want — so the finished file reads cleanly on phones, prints without wasted paper, and looks professional when shared.
This free crop pdf tool works entirely in your browser: upload your file, drag the blue crop box over the area to keep, or remove 10% or 20% of the margins in one click. Apply the crop to a single page or the whole document, then download. Cropping only changes the visible area — text stays selectable and quality is untouched. No signup, no watermark, nothing uploaded.

How to Crop PDF Pages Online
- Upload your PDF. Click the drop zone or drag the file onto it. The first page appears in the preview, rendered right in your browser.
- Set the crop box. Drag the blue box to move it, or pull its corner and edge handles to resize. The dimmed area outside the box is what gets hidden.
- Use a preset (optional). Remove 10% margins or Remove 20% margins shrinks the box evenly on all sides — the fastest way to tidy up scanned pages.
- Check the live readout. The crop size shows in points and inches as you drag, so you know exactly how big the result will be.
- Choose the scope. Apply the crop to this page only or to all pages at once — handy when every page shares the same margins.
- Download. Hit Apply Crop & Download PDF and save the cropped file.
Flip through pages with Prev/Next to position the box on the right page before applying. If a page is rotated sideways, fix it first with our Rotate PDF tool so the crop box matches the content orientation. The download is saved as yourfile-cropped.pdf.
Crop PDF Features

Crop PDF Margins: Cropping vs. Trimming Explained
People use the words crop and trim interchangeably, but in PDF-land they mean slightly different things. Cropping sets the page’s crop box — a rectangle that defines which part of the page viewers display. Content outside the box is hidden from view in every standards-compliant reader, but it is technically still in the file, and the crop can be reversed by resetting the box. Trimming, in print workflows, usually means physically cutting content away.
This tool crops. That is the right choice for everyday jobs: cleaning up scan margins, focusing a slide on its diagram, or removing a scanner’s dark edge. The page content itself is never re-rendered, so text stays razor-sharp and selectable, and file size barely changes. The crop box is one of the standard page-boundary boxes — CropBox alongside TrimBox and BleedBox — Like cropping an image, a PDF crop only changes which rectangle viewers display, which is why cropped files behave identically in every standards-compliant reader. If you need content permanently deleted rather than hidden — for example, to truly remove sensitive information — use a redaction tool instead of a cropper, because cropped-out content could be revealed by resetting the crop box. Our Redact PDF tool destroys the underlying data instead of merely hiding it.
One more honest note: the crop box applies in the page’s own orientation. If a page is rotated, the preview shows it as it will appear, and the box you draw matches what you see. For mixed-orientation documents, crop the odd pages individually using the this page only option rather than applying one box to all pages.
Remove White Margins from PDF Automatically
Most scans and exported documents carry the same flaw: a thick white border on every page that makes the content feel small, especially on phones and e-readers. Rather than drawing the crop box by hand on every page, hit Remove 10% margins to shrink the visible area evenly on all sides, or Remove 20% margins for heavily bordered scans. Pair that with the all pages scope and an entire document is cleaned up in two clicks.
Two caveats. First, the presets are even and centered — if your margins are lopsided (a dark scanner edge on the left, for instance), drag the box manually instead. Second, watch the footers: page numbers and fine print live in the margins, so an aggressive 20% trim can slice them off. Spot-check a few pages before downloading, and you will get tidy, professional-looking pages with nothing lost. If your scan quality is poor to begin with, consider running the file through our OCR PDF tool as well — clean, cropped pages give OCR more room to work and a less noisy result.
Tips for Clean PDF Crops
- Leave a breathing margin. Cutting text right at the glyph edges looks cramped and can clip characters in some viewers. Keep a small cushion.
- Fix the worst page first. Preview each page and crop the one with the biggest margins first — that box often works well for the rest via all pages.
- Watch for page numbers. Aggressive margin removal can slice off footers and page numbers. Zoom mentally: if the footer matters, crop less.
- Scans vary — spot-check. Auto-fed scanners shift pages slightly. If margins differ page to page, crop the outliers individually instead of batching.
- Do not crop away needed content. The dimmed preview shows exactly what disappears — trust it before you download.
- Remember crop is reversible. Cropping hides rather than deletes, so it is never a substitute for redaction of sensitive data.
Crop PDF: Frequently Asked Questions
How do I crop a PDF online for free?
Upload your PDF to this crop pdf tool, then drag the blue crop box to the area you want to keep — or click Remove 10% margins or Remove 20% margins to trim white borders in one step. Choose whether to apply the crop to the current page or to all pages, then download. Everything runs in your browser with no signup, no watermark, and no file-size games, and the original text stays selectable.
Does cropping a PDF reduce its quality?
No. Cropping only changes the page’s crop box — metadata that tells viewers which rectangle of the page to display. The underlying text, fonts, and images are untouched, so everything stays exactly as sharp as the original and text remains selectable. Because no re-rendering happens, the file size barely changes either. Cropping is a layout operation, not a conversion, which is why it is instant and lossless.
Can I crop all pages of a PDF at once?
Yes. Set the crop box once, select the All pages option, and the same rectangle is applied to every page of the document. This is ideal when all pages share the same layout — a scanned report with uniform margins, or slides exported from the same template. If individual pages differ, which is common with mixed scans, use the This page only option and position the box separately for each page before downloading.
Is cropped-out content permanently removed from a PDF?
No — and this matters. Standard PDF cropping only hides content outside the crop box; the data stays in the file and the crop can be reversed with the right software. For everyday cleanup that is fine, and it keeps cropping fast and lossless. But never use cropping to hide sensitive information like signatures or ID numbers. For that, use a true redaction tool instead, which destroys the underlying data rather than just hiding it from view.
What is the difference between cropping and resizing a PDF page?
Cropping trims the visible area of a page — it cuts away margins or unwanted regions while the remaining content stays at its original size. Resizing changes the page dimensions or scales the content itself, making everything bigger or smaller. To remove white borders around a scanned receipt, crop. To fit a large poster onto A4 paper for printing, resize. They solve different problems, and mixing them up usually means either lost content or blurry output.
