How to Crop PDF Pages Online

Add Your PDF
Select one PDF file or drop it into the workspace. Enter the correct password if the document is protected.

Drag and resize the crop box on the first-page preview until it surrounds the content you want to keep.
Crop and Download

How Does the PDF Cropper Work?
The CompressFly PDF cropper lets you trim white margins, scanner borders, and unwanted space from PDF pages with a visual crop box. Set the area you want to keep on the first-page preview, then apply the same crop across the entire document. Existing text and images are not re-encoded, so the cropped PDF keeps its original visual quality. Everything is processed locally in your browser, and your file is not uploaded to a server.
What "processed locally" means
- The PDF file is not uploaded to or stored on a processing server
- Cropping runs on your device inside the browser tab
- Passwords used to open protected PDFs are handled on your device
- The cropped PDF is created locally and downloaded from your browser
When Should You Crop PDF Pages?
A PDF cropper is useful when the document has the content you need but too much white space, uneven borders, or unwanted material around the page edges.
Remove White Margins from a PDF
Trim excessive white space around articles, reports, slides, and other PDF content.
Crop Scanned PDF Pages
Hide dark scanner edges, uneven borders, and extra space around scanned documents.
Crop PDF Pages for Printing
Tighten page boundaries before printing documents with wide or inconsistent outer margins.
Improve PDF Reading on Smaller Screens
Reduce unused page area so text and graphics appear larger on tablets and e-readers.
Why Use CompressFly to Crop PDF Pages Online?
Easy to Use
Trim distracting margins without recreating the document's layout. The visual cropper makes a simple cleanup accessible without specialist design skills.
Cleaner Page Views
Less empty space around the content can make a PDF more pleasant to read on screen. The result keeps attention on the material that matters.
Keep Text and Graphics Sharp
Cropping the visible page area does not require turning the document into screenshots. Existing text and graphics keep their visual quality within the area you retain.
No Software Setup
Tidy up page margins in your browser without installing a PDF application. It is a convenient option for an occasional scan or oversized page border.
Free Without an Account
Create a cleaner viewing copy without paying for an editor or signing up. The cropper and download are available for free.
Private Processing
Your document stays on your device while the cropped copy is created. There is no need to upload the PDF to a processing server.
Crop PDF FAQ
How do I crop a PDF online for free?
Crop a PDF in three steps: 1. Add one PDF file. 2. Drag and resize the crop box around the area you want to keep. 3. Click “Crop PDF,” preview the result, and download the cropped document for free.
Can I crop every PDF page at once?
Yes. Set the crop area on the first-page preview and the same coordinates are applied to every page in the document.
How do I remove white margins from a PDF?
Move the crop box inside the unwanted white margins, then resize it until it surrounds the content you want to keep. The selected area is applied across the entire PDF.
Can I crop a PDF without losing quality?
Yes. Cropping changes the visible page area without re-encoding embedded images or converting existing text into pictures. Content inside the crop area keeps its original visual quality, and searchable text remains searchable.
What happens when PDF pages have different sizes?
The crop coordinates are calculated from the first page and then reused across the document. Pages with different dimensions or orientations may therefore be cropped differently than expected, so review the finished PDF carefully.
Does cropping permanently remove hidden content?
No. Cropping changes the visible page area, but content outside the crop box remains in the PDF and may be restored. Use the Redact PDF tool when text, images, or other sensitive information must be permanently removed.
Will cropping reduce the PDF file size?
Usually not by much. Cropping hides content outside the visible page area without deleting it or recompressing images. Use the PDF Compressor when reducing file size is the main goal.
