How to crop a PDF
Scanned pages almost always come with too much white border, and documents exported from different programs often have uneven margins. Cropping trims those edges so the content fills the page — useful before printing, before merging into another document, or just to make a scan easier to read.
Set how much to trim from the top, right, bottom, and left as a percentage of the page. The preview shows the first page with a red box around what stays visible, so you can see exactly what will be cut before you commit. Leave the pages field blank to crop every page, or type a page or a range to crop only those.
One honest limit: cropping hides the margins — it does not delete them. The content outside the crop box stays inside the file, it is just not shown. For reading, printing, and merging that makes no difference, and it is also why cropping is instant and loses no quality. If the hidden content must be truly gone from the file, the document has to be rebuilt, which this tool does not do.
Everything runs in your browser, so the document never leaves your device. There is no daily limit.

Frequently asked questions
Does cropping delete the trimmed content?
No — and this matters. Cropping hides the margins; the content outside the crop box stays inside the file, it is just not shown. For reading, printing, and merging that makes no difference.
Can I crop only some pages?
Yes. Leave the pages field blank to crop every page, or type a page like 5, or a range like 2-4.
Does cropping change the quality of my pages?
No. The pages are not re-rendered — only the visible area changes — so text and images keep their original quality.
Are my files uploaded anywhere?
No. Cropping happens entirely in your browser. Your PDF never leaves your device.
