How to crop PDF pages with OnyxPDF
- Drop your PDF into the tool — the page renders for you.
- Drag a box over the area to keep, or switch to margins mode and type exact values.
- Apply to the current page or the whole document.
- Click “Crop & Save” and download the result.
Why do it in your browser instead of uploading?
- Visual cropping: you draw the keep-area on the actual page instead of guessing point values.
- Free — several competitors gate crop behind Premium/Pro tiers.
- Great for cleaning scans and removing printer-margin junk before printing or sharing.
- No upload: crop a sensitive page on your own device.
Good to know (honest limits)
- Cropping changes the page box — it hides the area outside the box rather than deleting its content. If content must be truly gone (privacy, legal), use Redact PDF.
- A crop applied to all pages uses the same box on each; pages with different layouts may need individual passes.
Frequently asked questions
Does cropping delete the content outside the box?
No — it hides it by shrinking the page box; the underlying content still exists in the file. For permanent removal, use Redact PDF.
Can I crop all pages the same way at once?
Yes. Set the box once and apply it to the whole document — the standard fix for uniform scan margins.
Why would I crop a PDF?
To remove excessive margins for reading on small screens, cut a table or figure out of a page, or tidy scanned documents before printing.
Are files uploaded?
No. The page renders and the crop is applied entirely in your browser.
