Analyze PDF

Inspect pages, size, fonts, images, security and metadata

About this tool

Reports what a PDF actually contains: how many pages, its size on disk, page dimensions, which fonts are embedded, how many images it holds, whether it is encrypted, and its metadata. Useful for working out why a file is unexpectedly large, why it renders differently elsewhere, or whether it is protected.

Key features

  • No download needed

    The report is shown in the page rather than saved as a file.

  • Explains file size

    Image and font counts usually account for a PDF that is larger than expected.

  • Shows security state

    Tells you whether the document is encrypted before you try to edit it.

  • Private

    The file is sent over HTTPS and removed from the server after analysis.

Frequently asked questions

Does analyzing change my file?
No. The document is read only, and nothing is written back or returned to you as a file.
Why is my PDF so large?
Usually embedded images, and sometimes fully embedded font families. The image count here is the first thing to check; Compress PDF or Optimize PDF can then reduce it.
What does "encrypted" mean here?
The document has a password or permission restrictions. Use Unprotect PDF with the password to remove them before editing.
Why do fonts matter?
A PDF that does not embed its fonts renders with substitutes on machines that lack them, which is the usual cause of a document looking different elsewhere.
