Crop PDF
To crop a PDF, upload the file and drag a crop box over the page to trim margins or isolate a region. Apply it to one page or every page. Cropping changes only the visible page boundaries, runs entirely in your browser, and does not reduce content resolution.
Trim and crop PDF pages by applying an even margin.

Frequently
Asked
Questions
Quick answers about this PurePDF workflow.
Is cropping a PDF free?
Yes. PurePDF Crop is 100% free with no signup or watermarks.
Do my files get uploaded to a server?
No. Cropping runs entirely in your browser — your PDF never leaves your device.
Can I crop all pages at once?
Yes. Draw one crop area and apply it to every page, or crop pages individually.
Does cropping delete the content outside the crop box?
Cropping adjusts the visible page area. The exported PDF displays only the cropped region in all standard PDF readers.
Can I remove white margins automatically?
Yes. Use the crop preview to trim whitespace and tighten margins for e-readers or printing.
Will cropping reduce quality?
No. Cropping only changes the page boundaries — the content resolution is untouched.
