About this tool: Crop PDF
Crop PDF changes the visible crop box on each page, which is useful for hiding scanner margins or narrowing a page without rasterizing it.
How it works
The tool sets each page crop box based on the entered point margins.
Practical example
Apply 18-point margins to all four sides of a scanned PDF to remove excess white border from view.
Important notes
72 PDF points equal one inch. Cropping changes the visible area but may not permanently erase hidden source content.
Privacy & processing
Crop-box editing runs locally in your browser.
Frequently asked questions
Does Crop PDF upload my file?
No. This Phase 14 implementation performs the advertised processing in the browser unless the page explicitly states otherwise.
What files work with Crop PDF?
Use a normal PDF within the browser size limits shown by the uploader. Unsupported, encrypted or severely corrupted files can return a clear error.
Can I use Crop PDF on a phone?
Yes. The interface is responsive, although larger PDFs can require more memory and processing time on mobile devices.
Will the output always look identical to the source?
Not always. The exact result depends on the operation and the PDF structure. NexterHub explains transformations that can change text, layout or image quality.
What should I do if processing fails?
Try a smaller or different PDF, remove password protection where required, and confirm that the file opens normally in a standard PDF viewer.
