What does it mean to embed fonts in a PDF?

Embedding means the actual font file is stored inside the PDF, so the document renders correctly on any computer — even if the recipient does not have the font installed. It is required by most printers and by the PDF/A and PDF/X standards.

Why are some fonts not embedded already?

Usually because the original export (commonly from Word or LibreOffice) did not enable font embedding, or because the font is license-protected. Our tool finds them automatically and embeds them if we have a matching font file on our server.

Which fonts can you embed?

We have 377 system fonts installed — all standard Linux fonts (DejaVu, Liberation, Noto, Lato) plus usable free substitutes. Commercial fonts like Helvetica or Adobe Caslon cannot be legally embedded by us — use our Outline Fonts tool instead.

Does the PDF get larger after embedding?

Slightly. A typical font is 50–200 KB. A PDF with 3 missing fonts typically grows by 200–500 KB. In return it becomes self-contained and can be printed anywhere without font substitution.

Does the text change appearance?

No. Unlike outlining (which converts text to curves), embedding preserves the original font metrics and kerning. The text remains searchable, copyable, and editable in Acrobat.

What is the difference between embedding and outlining?

Embedding stores the font file inside the PDF (small filesize overhead, text stays editable). Outlining converts text to curves (larger file, text is no longer text). Embedding is preferred when possible; outline is the fix when a font cannot be embedded.
