2026-10 · Colors in the dashboard

-
2026-10 · Colors in PDF and EPS
Colored QR codes in PDF and EPS too — as print colorsfg, bg and stored colors now show in qr.pdf and qr.eps as well. Black and grey as grayscale on one plate, other colors as CMYK in whole percent, background like the SVG.
-
2026-09 · Deletion
Deleted accounts stop redirecting, concurrent changes report 409After an account is deleted, a static code stops redirecting on the next call of its short link instead of up to 24 hours later. Two simultaneous deletions send only one webhook, two simultaneous logo changes report 409.
-
2026-09 · Expiry
A changed expiry applies within about a minuteA PATCH to expires_at now clears the code's redirect cache, and the change applies within about a minute. Before, a code could keep redirecting or keep reporting itself expired according to the old expiry for up to 24 hours.
-
2026-09 · Colors on the code
Store colors on a QR code — with a contrast checkPATCH /v1/codes/:id accepts appearance: foreground and background color stay on the code, SVG and PNG draw them without parameters, PDF and EPS follow. Below 1.5:1 contrast the API says no.
-
2026-09 · Colors and error correction
Colored QR codes and selectable error correction — via the APIfg, bg and ecc on qr.svg, qr.png, qr.pdf and qr.eps: colored codes, transparent PNGs and more robust error correction for print. Invalid values are ignored, never an error.
-
2026-09 · Logo in PDF and EPS
PDF and EPS now show the logo just like SVG and PNGVector print templates get the logo too: PDF and EPS now embed the same pixels as SVG and PNG, with the same error correction H and the same 5-minute cache.
-
2026-09 · Logo in the QR code
A logo in the middle of the code — without it stopping scanningA QR code with your own logo in the middle, no separate image editing needed and without the code breaking. Upload it in the dashboard or via API, embedded straight into SVG and PNG.
-
2026-08 · Named API operations
Every API operation now has a stable name — and qr3.app says what it is forGenerators no longer invent method names, they read them from the specification. And anyone letting an assistant use qr3.app now gets guidance instead of an inventory.

2026-08 · Machine-readable API
qr3.app now serves Markdown — and describes its API machine-readablyRead the homepage or the blog with a program and you now get Markdown instead of HTML — and the API description sits at a fixed, standardised address.
-
2026-08 · 24 languages on scan
The pages your customers see now speak 24 languagesWhoever scans your code sees two qr3-hosted pages. Both were hard-wired to German, no matter where the scan came from. That is fixed.
-
2026-08 · Security headers
