PDF Page Inspector FAQs

Questions about checking PDF page size and boxes

1. What does the PDF Page Inspector do?

It lets you drag‑and‑drop a PDF and instantly see each page’s size (mm, pt, px), orientation, MediaBox, CropBox, BleedBox, TrimBox, and ArtBox. It is ideal for spotting layout issues before you print or merge files.

2. Do you upload my PDF to a server?

No. Everything runs entirely in your browser and the file never leaves your computer, so sensitive documents stay private.

3. Which browsers are supported?

The inspector works on any modern desktop browser that supports ES Modules

4. How do I reset or remove a CropBox or MediaBox from a PDF?

You can rebuild the PDF with Ghostscript and discard the existing boxes:

gs -o repaired.pdf -sDEVICE=pdfwrite -dPDFSETTINGS=/prepress -dSAFER -dNOPAUSE -dBATCH -f yourfile.pdf

Ghostscript re‑renders every page and writes a fresh MediaBox that starts at (0 0). The new file(repaired.pdf)should load with the correct boxes in the Page Inspector.
