Guide
How to crop a PDF
1
Select Your PDF
Drag and drop a PDF or click to choose one. The first page shows up as a live preview.
2
Set the Margins
Move the top, bottom, left, and right sliders to trim each side. The clear area in the preview is what stays.
3
Crop and Download
Click Crop and Download. The same crop is applied to every page and a new PDF is saved to your device.
Cut the Extra Space Around Your PDF
Plenty of PDFs come with more whitespace than you need, wide print margins, a header band you want gone, or scanned pages with borders around the content. That empty space wastes screen room and ink, and it makes a document look unfinished.
Cropping fixes it by shrinking the visible area of each page. You set how much to cut from the top, bottom, left, and right, watch the preview update on the first page, and the tool trims every page to match. The text and images are untouched, only the framing changes.
It works by setting a new crop box on each page rather than re-rendering anything, so quality stays exactly the same. Everything runs in the browser, which means even private documents never leave your computer.

FAQ
Frequently Asked Questions
Common questions about cropping PDFs.
How does cropping a PDF work?
It sets a new crop box on each page, which is the area a viewer shows. The content outside that box is hidden, so the page looks trimmed without anything being re-rendered or re-compressed.
Does it crop every page the same way?
Yes. The margins you set are applied as the same proportion to every page, so a 10 percent top trim cuts 10 percent off the top of each page regardless of its size.
Will cropping lower the quality?
No. Cropping only changes the visible area, not the underlying text or images, so everything stays as sharp as the original.
Can I get the cropped-off content back?
The trimmed area is hidden by the crop box, not deleted, but this tool saves a cropped file. Keep your original if you might need the full pages again.
Is there a preview before I save?
Yes. The first page is shown with a clear box over the area that will be kept, and it updates live as you move the sliders.
Is this crop PDF tool free?
Yes, it is completely free with no signup and no limits. Everything runs in your browser, so your file stays on your device.
