Hi Product Hunt! 👋
I built PdfRuler because I kept hitting the same problem: someone sends a PDF (a flyer, a packaging die-line, a drawing) and asks "is this really 85 x 55 mm?" The usual answers are a screenshot with a guessed scale or a heavy desktop app.
PdfRuler is a browser tool that reads sizes from the PDF itself, so the numbers are the same at 50%, 100% or 400% zoom.
What it does:
- Rulers around the page in mm, cm, in, pt or px, with a movable origin
- Pick: click a box or line and get its exact size, read from the vector data (not pixel guessing)
- Auto-measure for crop marks, margins and boxes
- Snap to content edges, plus draggable guides
- Page boxes: see the real Media, Crop, Bleed, Trim and Art boxes
- Loupe (4x), text and arrow annotations, full undo/redo history
- Tabs and split view to compare two versions side by side
- Save an annotated copy. Your original is never modified.
Privacy: everything runs client-side. Your file never leaves your device. There is no upload and no account.
There is also a "Try a sample" button, so you can play with it without a file.
I'd love to hear what you measure with it, and which feature you'd want next.
Thanks for looking! 🙏
