Letters Crop PDF Online — Trim Margins and Borders
To trim a PDF, enter how much to cut from the top, bottom, left and right edges — in mm, points, inches or percent — and download the cropped file. Crop every page or only the ones you list, such as 1-3,5; the text stays sharp and selectable because nothing is turned into an image.
Crop PDF Online Free
Crop your PDF pages to remove unwanted white margins, scanned borders or excess space. Enter the exact amount to trim from the top, bottom, left and right in millimeters, points, inches or percent, and apply it to every page or just a chosen range.
Cropping is fully lossless: the visible area is adjusted without re-rendering or re-compressing your content, so text stays sharp and quality is identical to the original.
How to crop a PDF
- Upload the PDF you want to crop.
- Enter the margins to trim and pick the unit.
- Click Crop PDF and download the trimmed file.
Frequently Asked Questions
About Crop PDF
Confileo's Crop PDF tool trims the visible page area of a PDF to remove scanner borders and wide margins. It works in any browser, free to start and without signup, and a file sent to our server is deleted automatically after processing.
Cropping a PDF trims the visible page area — cutting away scanner borders, wide margins, headers left over from another document, or the black edge that appears when a page was photographed rather than scanned. The content you keep stays exactly as it was; the page simply gets smaller edges.
You set how much to trim from each edge and apply it to every page or to the pages you list, then download the result. Nothing is installed and the original file on your device is untouched, so you can try a tighter crop and start over if you cut too close.
The reason cropping matters is usually reading, not aesthetics. A page with 4 cm of white on both sides forces a phone to shrink the text to fit, so a document that reads fine on a laptop becomes unusable on a commute. Trimming the margins lets the same text render far larger on a small screen, which is the single cheapest readability improvement you can make to a scanned book or article.
One thing worth understanding: cropping hides content rather than deleting it. PDF stores a full page and a visible window onto it, and cropping moves that window. The trimmed area is no longer displayed or printed, but it is still inside the file and can be restored by anyone who resets the crop box. If your goal is to remove sensitive information rather than tidy the layout, crop is the wrong tool — use PDF redaction, which deletes the content itself.
Because the cropped-away area is retained, cropping alone will not shrink your file. If you need a smaller download, run the cropped document through Compress PDF afterwards.
Your file is processed and then deleted from the server, and the original stays as it is on your device.

Crop PDF — Frequently asked questions
Does cropping make the file smaller?
No. The trimmed area is retained inside the file, so run Compress PDF afterwards if you need a smaller download.
Does cropping delete the content I cut off?
No. It hides it from view and print. To remove sensitive information permanently, use PDF redaction instead.
Can I crop every page at once?
Yes. Leave Pages on "all" and the same margins are trimmed from every page; enter a range such as 1-3,5 to crop only those pages.
Why crop a PDF at all?
Mainly readability. Trimming wide margins lets the text render much larger on a phone, which is the cheapest fix for a scanned book or article.
Is the original file changed?
No. You download a new cropped copy and the original stays as it is on your device.
Can I undo a crop?
Not in the downloaded file, so keep your original. Cropping again from the original is the reliable way to adjust it.
How do I crop the margins of a PDF?
Upload the file, enter how much to trim from the top, bottom, left and right — in millimetres, points, inches or percent — and download the trimmed PDF. Every page, or a range you name such as 1-3,5, is cropped in one pass.
Why would I crop a PDF instead of resizing it?
Cropping removes unwanted edges — wide scanner margins, a header strip, a watermark band at the foot of the page. Resizing would shrink the whole page including its content, so the clutter would simply come along at a smaller size.
Does cropping delete the text outside the visible area?
Cropping changes the visible page boundary, so hidden content may still exist in the file even though it does not display or print. To remove sensitive information permanently, use the PDF Redaction tool instead.
Is the text still selectable after cropping?
Yes. Cropping adjusts the page boundary without converting anything to an image, so text stays selectable and searchable.
Is this tool really free?
You can try it free: 50 credits without an account and 300 with a free account, renewed on the 1st of every month. Every tool uses credits — file tools 3 per file and the heavy ones 12. No watermark, no credit card. Beyond the monthly credits, Pro gives open use with no credits to count, or you can buy a credit pack.
Do I need to create an account?
No. You can use the tool straight away without signing up or logging in.
Are my files safe and private?
Yes. A file sent to our servers travels over an encrypted HTTPS connection and is deleted automatically after processing; tools that work in your browser never upload it. We don't open, read or sell your files.
Does it work on my phone?
Yes. The tool runs in any modern browser, so it works the same on desktop, tablet and mobile with nothing to install.
