How to crop a PDF online

Cropping trims the visible page area so that margins, headers or stamps get dropped from the output — without touching the underlying text, images or vector detail. Everything happens locally in your browser with pdf-lib and pdf.js, so your document never leaves your device.

  1. Add your PDF

    Drag and drop a PDF file onto the tool, or click to browse. Only one document is needed per crop operation.

  2. Set the crop area

    Drag the corner and edge handles on the live page preview to define the visible area. Use the numeric inputs for exact margins in points.

  3. Crop all or per page

    Choose Crop all pages uniformly to apply one margin to every page, or Crop per page to fine-tune individual pages as you flip through them.

  4. Crop and download

    Click Crop PDF and the cropped document is built right in your browser — usually in a couple of seconds — then saved to your device.

When cropping a PDF comes in handy

Scan cleanup

Remove the black or white borders around phone-scanned documents so they look clean when printed or shared.

Printing

Trim excessive margins so a PDF fits more comfortably on paper and wastes less toner.

Publishing

Crop awkward whitespace or stray headers/footers from a submitted report without re-exporting from the original app.

Key features

Visual drag handles

Eight corner and edge handles on a live page preview give pixel-accurate control over the crop area.

All pages or per page

Apply identical margins to every page, or switch to per-page mode and crop individual pages independently.

Lossless output

Cropping only updates each page's CropBox metadata, so text, images and vectors stay untouched — no quality loss.

Supported formats

  • Input: PDF file (.pdf)
  • Output: a standard PDF (.pdf) with each page's CropBox narrowed to the selected margins

Privacy and security

Cropping runs entirely in your browser using pdf-lib and pdf.js. Your file is read into local memory, cropped on your own device, and saved back by your browser when you click download — there is no upload step and nothing is stored after you close the tab.

Limitations

  • One PDF per operation; very large documents are limited by your device's available memory.
  • Password-protected PDFs can be cropped only if you can open them.
  • Cropping changes the visible printable area but does not rescale page content.
  • Form fields and annotations inherit the new CropBox; some may shift near the cropped edge.

Frequently Asked Questions

How do I crop a PDF online?

Upload your PDF, drag the crop handles on the page preview to trim the margins you want removed, then click Crop PDF. The cropped file builds in your browser and downloads instantly.

Can I crop every page at once?

Yes — choose Crop all pages uniformly and the margins you set are applied to every page in the document.

Can I crop only some pages?

Yes — switch to Crop per page and use the page arrows to move between pages. Each page keeps its own crop settings.

Will cropping reduce my PDF quality?

No. Cropping only adjusts each page's CropBox metadata — the original page content (text, images, vectors) is never re-encoded, so quality is unchanged.

Is my PDF uploaded to a server?

No. All cropping runs locally in your browser with pdf-lib and pdf.js. Your file is never uploaded or stored — close the tab and it is gone.
