Standard pre-press crop. Keeps the visible area defined by the file's CropBox.

How It Works

Boundary-level crop, no re-rendering

The tool reads each page in your PDF and replaces the printable boundary with the one requested (CropBox, TrimBox, BleedBox, or ArtBox). Text, vectors, and images stay at full quality. The whole operation runs locally inside your browser tab.

Frequently Asked Questions

What is the CropBox in a PDF?
The CropBox is one of the page boundary boxes defined inside every PDF. It tells viewers and print engines which part of a page to display or print. Most PDFs also carry a larger MediaBox (the physical sheet), and pre-press files usually carry BleedBox, TrimBox, and ArtBox as well. Cropping to the CropBox makes the visible region the new page boundary.
Why crop a PDF to its CropBox?
Pre-press and print teams receive files where the full sheet includes bleed, registration marks, and printer notes outside the trim line. Sending those pages to a customer or downstream tool produces a cluttered preview. Cropping to the CropBox or TrimBox produces a clean file that shows only the intended page content.
Does this tool re-render the page content?
No. The crop is applied at the page boundary level. Text remains selectable, vector artwork stays sharp, and embedded images keep their original resolution. The visible region simply becomes the new MediaBox.
What is the difference between CropBox, TrimBox, BleedBox, and ArtBox?
CropBox is the visible region in viewers. TrimBox is the final page size after the print is trimmed. BleedBox is the trim plus a small overlap to absorb cutting tolerance. ArtBox is the meaningful artwork region inside the page. This tool can crop to any of the four, depending on how the file was prepared.
Does the tool upload my file?
No. Everything runs entirely in your browser tab. Your PDF is processed locally and never leaves your device.
What if my PDF has no CropBox?
If a PDF has no explicit CropBox, the PDF specification says the CropBox is the same as the MediaBox. In that case the crop is a no-op and the file is unchanged. Switch to TrimBox or BleedBox if the file uses those boxes for the print boundary.
Will hyperlinks, bookmarks, and form fields survive?
Hyperlinks and bookmarks are preserved. Some interactive form fields may be flattened depending on how the source file is structured, but text and visual content remain intact.
Is the PDF Crop tool free?
Yes, completely free. No account, no sign-up, no limits.
