Crop PDF
Trim the margins of PDF pages with a live preview.
Your files stay with you. Your files never leave your browser. This tool runs on your device: nothing is uploaded to our servers, so there is nothing for us to store or see.
How to use it
- Choose your PDF.
- Enter how many percent to cut from each side and check the preview.
- Press Crop PDF and download the result.
Cropping sets the visible area of each page. The trimmed-off content stays inside the file, so do not use it to hide private information.

Questions people ask
How do you crop the margins of a PDF?
Choose your PDF, enter how many percent to cut from each side and check the live preview, then press Crop PDF and download the result. Every page from the start page on gets the same cut. Cropping hides content rather than deleting it, so don't use it to remove private details.

How do I crop a PDF?
Choose your PDF, enter the percentage to cut from the top, bottom, left and right, and watch the live preview. When it looks right, press Crop PDF and download the result. The original isn't changed, and nothing is uploaded from your device. It only takes a moment.
Is the cut-off area deleted?
No. Cropping changes the visible area of each page, but the trimmed content stays inside the file. Anyone with PDF editing tools could reveal it again. Never use crop to hide account numbers, signatures or other sensitive details; use a proper redaction tool for that.
Does it crop all pages the same way?
Yes. Every page from the start page onwards gets the same percentage cut. Pages of different sizes are cut in proportion, so the result stays consistent. If one page needs a different crop, split it out first, crop it separately and merge again. Preview a few pages first.
Is my PDF uploaded?
No. Everything runs on your device, so the file is never uploaded. That keeps documents private while you trim them. Once the page has loaded, cropping works even without an internet connection. Nothing is stored, and there's no account to create, so no copy of the document is kept anywhere.
Why crop a PDF at all?
Mostly to make documents easier to read on phones and tablets by removing wide white margins, or to cut off dark scanner edges. Cropping can also tidy pages before printing on a different paper size. It's a visual fix, not a way to remove information.
Can I crop a scanned PDF?
Yes. Cropping works on scanned pages the same way, which is handy for removing black borders, shadows or the edge of a desk that ended up in a phone scan. Check the preview so you don't cut into the scanned text. Small percentages are usually enough for that.
Will cropping reduce the file size?
Usually not much, because the trimmed content stays in the file. If you need a smaller file, use Compress PDF afterwards. For scans, the Medium level of compression often reduces size a lot while keeping text readable. Text PDFs are usually small already, so they rarely need it.
Does cropping change quality?
No. The page content isn't redrawn, so text and images keep their original quality. Only the visible area changes. Selectable text stays selectable within the cropped area, and printing the page uses the new, smaller visible area. Zooming in looks exactly as sharp as before cropping.
Can I crop just one side?
Yes. Enter a percentage only for the side you want to trim, such as the left margin, and leave the others at zero. The preview updates as you type, so you can find the right amount quickly without guessing. Most margins need only a few per cent.
How do I avoid cutting off text?
Use small percentages first and check the preview on several pages, especially pages with content near the edges, such as page numbers or footers. Increase the crop gradually. If some pages have wider content, a smaller crop for all pages is safer. Footers are easy to miss.
Can I crop a PDF on my phone?
Yes, in modern mobile browsers. Enter the percentages, check the preview and download. Cropping is a good fix for documents that are hard to read on a phone because of large white margins around small text. No app or account is needed for any of it.
Can I crop a password-protected PDF?
Not directly. Open it with its password, save an unlocked copy, crop that, then delete the unlocked copy if it's sensitive. Remember that the cropped copy still contains the trimmed content, so treat it as you would the original. The original stays protected throughout. Nothing is uploaded.
What's the difference between crop and resize?
Cropping trims the visible area of the page. Resizing would change the page dimensions and scale the content. This tool crops. If you need a different paper size for printing, most print dialogues can scale pages to fit, which works well after cropping. Check the print preview.
Can I start cropping from a later page?
Yes. Set the start page, and pages before it stay uncropped. That's useful when a cover page should keep its full design while the inner pages are trimmed for easier reading on screens and phones. The preview shows exactly which pages are affected before you save.
Is it free?
Yes. Cropping PDFs is free, with no sign-up, no watermark and no daily limit. Like the other Marketiism PDF tools, it runs in your browser, so your documents stay on your device the whole time. Nothing is added to your file, and business use is fine.
