# PDF and EPS now show the logo just like SVG and PNG

24. september 2026

dashboard api print

Until recently, a code could carry a logo in its center — but only the
**SVG** and **PNG** downloads actually showed it. **PDF** and **EPS** — the
two formats that go to a print shop as artwork — left it out. That is fixed
now.

### What changes

All **four** formats now embed the logo alike, as actual pixels centered on
the same area as in SVG and PNG:

- **PDF** gets the logo as an embedded image (an image XObject in the PDF
structure) — both in the default square format and on the A4 print sheet
(`?format=a4`).

- **EPS** gets the logo via a PostScript image dictionary that only needs a
Level 3 capability on the logo path — without a logo, the file stays
exactly as before (PostScript Level 2).

With a logo set, all four formats raise the error correction to `H` and serve
`Cache-Control: public, max-age=300` instead of the usual 24 hours — the same
rules that already applied to SVG and PNG. Without a logo, PDF and EPS stay
byte-identical to before, with the unchanged 24-hour cache.

If the logo image itself can’t be prepared — a corrupted stored object, for
example — error correction stays at `H`, but the area reserved for it stays
empty instead of showing an image. The PDF or EPS remains scannable either
way; the server never returns an error for this.

### For printing

Since all four formats now show the same logo, which one fits your print
artwork is purely a question for your layout program — vector for PDF/EPS,
raster for PNG, SVG for either. As always: do a **test scan on the real
material** before a full print run, and never mix files from different
states.

A full guide with every detail lives at
[Logo in the QR code](https://docs.qr3.app/en/guides/logo-in-qr-code/).

### What you need to do

Nothing. A code without a logo does not change in any format — no different
pattern, no different cache time, no different download. A code with a logo
picks up the logo in its PDF or EPS on the next download, automatically.
