Scanned contracts, exported slide decks, and old book chapters often carry excess white space or stray margin marks that make them awkward to read on a phone or tablet. PDF Guru's crop tool lets you draw a new boundary box over one page and apply it to the whole document, or crop each page individually when a file mixes portrait and landscape content. There's nothing to install; the cropping happens in your browser tab.
Cropping is different from resizing: the page dimensions shrink to match your selection, but the underlying text, images, and vector graphics keep their original resolution. That means a cropped invoice or research paper still prints sharply and stays searchable if it had selectable text before. Because the file never leaves your device for processing, sensitive documents such as signed agreements or medical scans stay private throughout the edit.
How to use Crop PDF online
- 1
Upload your PDF
Drag the file into the browser window or pick it from your device. Files up to 100 MB are supported and nothing is uploaded to a server.
- 2
Select the crop area
Drag the corner handles on the page preview to set new top, bottom, left, and right margins for the visible content.
- 3
Choose which pages to affect
Apply the same crop box to every page, or switch to per-page mode if your document mixes different page sizes or orientations.
- 4
Download the cropped file
Confirm the preview looks right, then save the trimmed PDF to your device; the original file is discarded from memory.
When people use this tool
Removing scanner borders
Flatbed scans often include a dark strip or curled edge along one side; cropping cuts it out before you archive or email the pages.
Preparing slides for print
Presentation exports sometimes leave wide white margins around the actual slide; cropping tightens the layout for a handout booklet.
Isolating a single article from a scanned page
When two newspaper or magazine columns are scanned together, cropping lets you keep just the column you need.
Fitting PDFs to e-readers
Academic papers formatted for A4 printing can look cramped on a small screen; cropping the margins makes the text area fill more of the display.
What you get
Visual drag-to-crop
Adjust the crop box by eye on a live page preview instead of typing coordinates, with instant visual feedback.
Per-page or whole-document cropping
Apply one uniform crop or set different boundaries for pages that were scanned or exported at different sizes.
No quality loss
Cropping only changes the visible page boundary; text stays selectable and images keep their original resolution.
