How to use this tool
- Drop in any PDF.
- See its page count, file size, PDF version, and document properties instantly.
- Check the page sizes list if the PDF mixes page dimensions or orientations.
Frequently asked questions
- What page size counts as "Letter" or "A4"?
- Standard paper sizes are matched by their dimensions in PDF points (within 1pt, to allow for rounding) — Letter (8.5″ × 11″), Legal, Tabloid, A3, A4, and A5, in either portrait or landscape. Anything else is shown as a custom size with its exact dimensions in points and inches.
- Can this open a password-protected PDF?
- No — if a PDF requires a password to open, this tool can't read it. Use Remove PDF Password first if you know the password, then check its info here.
- Does this tool change anything in my PDF?
- No — this is read-only. Nothing is modified or re-saved. If you want to edit the title, author, or other properties, use the PDF Metadata Editor instead.
- Is my PDF uploaded anywhere?
- No — everything is read entirely in your browser. The file never leaves your device.
How GetByteRush compares
Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
| Feature | GetByteRush | Typical online tools |
|---|---|---|
| PDF ever leaves your device | No — read in this tab | Yes, uploaded to process |
| Shows page-by-page dimensions | Yes | Varies — often just page count |
| Account required | Never | Often, past a certain usage level |
("Typical online tools" reflects publicly documented behavior of common free file-processing sites as of 2026 — always check a specific competitor's own privacy policy and pricing page, since these details change.)
