Inspect a PDF's metadata and properties
Open a PDF and see what's really inside it — the hidden details a reader doesn't show you. Drop a file in and you get its metadata, exact page sizes, page count, encryption status, and rough counts of embedded fonts and images. It's the quick way to answer questions like "who made this and when," "why is this file so big," or "is this the A4 version the portal asked for." Everything is read on your device; nothing is uploaded.
What you can check
- General info — file name, size, page count, and whether the PDF is encrypted.
- Metadata — title, author, subject, the app that created it, the producer, creation and modification dates, and keywords.
- Resources — estimated counts of embedded fonts and images, a clue to why a file is large.
- Page dimensions — width and height of each page in points, millimetres, and inches.
When this is handy
- Before you submit — confirm the page size and page count match what a form or printer expects.
- Checking origin — see the author and creating application to verify where a document came from.
- Diagnosing big files — lots of embedded images usually explains a heavy PDF; then run Compress PDF.
- Privacy review — spot author or software names you'd rather not share, then strip them with the PDF cleaner.
A note on accuracy
Metadata fields are only as good as the app that wrote them — plenty of PDFs ship with blank or default author and title fields, and dates can be missing. Font and image counts are estimates read from the PDF's structure, not a full extraction. For pulling actual images out, use Extract images from PDF; to remove metadata you don't want to share, use the PDF cleaner.
Privacy
Your PDF stays in your browser. Reading metadata and measuring pages happens locally — the file is never uploaded or stored.

Frequently asked questions
Can I see the embedded images and fonts?
It shows estimated counts of fonts and images detected in the PDF structure, which helps explain a large file. To pull the actual images out, use the Extract images from PDF tool.
Is the metadata always accurate?
Not always. Author, title, and dates are set by whatever app created the PDF, so many files have blank or default values. The tool reports exactly what is stored — it does not guess.
Are my documents uploaded?
No. Everything is read in your browser; your file never reaches PDF2atom. That makes it safe to inspect confidential documents.
Can I remove the metadata I see here?
Not on this page — this one only reads. To strip author, software names, and other metadata, use the PDF cleaner, or change individual fields with Edit PDF metadata.
Why does it say my PDF is encrypted?
It means the file has password protection or permission restrictions set. You can still see basic properties, but the content stays locked until it is opened with the correct password.
