How to Use the PDF Font Inspector Online

PDF Font Inspector: before and after PDF A BEFORE PDF FONTINSPECTOR PDF A AFTER

Every font in the PDF is listed with its type, whether it is embedded, and whether only the used glyphs were included. A font that is not embedded gets swapped for whatever the other machine has, which is why a CV looks right on your laptop and reflows on the recruiter's. Print shops and PDF/A checkers reject such files, so this tells you before they do.

Lists every font and shows which are embedded. A font that is not embedded is substituted by whatever the reader has, which is why a document can look correct on your machine and reflow on someone else’s — and why print shops reject files with unembedded fonts.

Why Inspect a Document Before Sending?

A file can look fine on screen and still fail a portal check because of its version, page size, fonts or hidden permissions. Inspecting it first shows those details plainly, and the helper tools split, merge and shrink data and office files.

“Check the file before someone else rejects it.”
  • Page count and size at a glance
  • Version and standard checks
  • Hidden attachments brought out
  • Data files split or merged
  • Fonts and links listed
  • Permissions shown before you share
  • Office files made smaller
  • Excel formulas explained

Popular Uses for Document Checkers

These checks answer the questions people have about a file before it goes anywhere.

  • Print shop checks Confirm page sizes, orientation and PDF/X before sending artwork to a printer.
  • Archive submissions Check whether a PDF meets PDF/A before submitting it to a court or registry.
  • Counting pages and words Find the page count and word count of a PDF for a quote or limit.
  • Checking links List every link inside a PDF to find broken or outdated addresses.
  • Font problems See which fonts a PDF uses and whether they are embedded for printing.
  • Shrinking Office files Make a heavy Word, Excel or PowerPoint file smaller before emailing it.
  • Splitting large CSVs Cut a huge CSV or JSON file into parts that other tools can open.
  • Excel formula help Check a formula for errors or turn a column number into its letter.

What You Can Do with the PDF Font Inspector

Understands PDF structure rather than treating the file as bytes

Reports what the file actually declares — fonts, permissions, encryption and PDF/A conformance

Reads the structure without rendering, so a file that crashes a viewer can still be examined

Tips and Good to Know

  1. It reports the problem, not the fix. To embed a missing font, re-export from the original application with embedding switched on.

  2. Encrypted PDFs hide their font tables. Unlock the file first if you have the password.

  3. For a full archival pass that also checks colour and metadata, use PDF/A Validator; this page covers fonts only.

Frequently Asked Questions

Answers to common questions about this tool.

Do I need to install anything to use the PDF Font Inspector?

No. PDF Font Inspector runs entirely in your browser — there is nothing to download, no extension and no desktop program. It works the same on Windows, macOS, Linux, Android and iPhone.

Is it safe to use the PDF Font Inspector online?

Safer than the usual alternative, yes. Most online tools upload your file to a server you know nothing about, where it sits until someone deletes it. Here the file never leaves your device — the processing happens in the page itself, so there is no server copy to leak, retain or sell.

Does PDF Font Inspector change my file?

The inspection tools only read the file and report what they find, so your document is untouched. Tools that split, merge or compress give you a new file and leave the original as it was.

What is PDF/A and do I need it?

PDF/A is a version of PDF made for keeping documents readable for many years. Some courts, government offices and archives ask for it. If a portal does not mention it, an ordinary PDF is fine.

Can I use PDF Font Inspector without signing up?

Yes. No account, no email and no fee. Drop in the file and the report or result appears on the page, ready to read or download.

Why was my PDF rejected by a portal?

Common reasons are a file that is too large, the wrong PDF version, a password, missing fonts or pages of the wrong size. Checking those details here usually points to the cause.
