Everything you can change

Circle, heart, hexagon, shield, speech bubble, flower, map pin, house and more, with decorative modules and 5 outlines.

Your logo

PNG, JPG, SVG or WebP. Error correction goes up to H automatically, and the modules behind the logo can be cleared.

Frames and captions

13 frames, from a simple label to a phone, ticket or polaroid, with your call to action in 5 fonts.

Saved brand templates

Save your design once and apply it to every new code. On a team plan, everyone in the workspace can use it.

Frames

Tell people what they'll get

A code on its own gets ignored. A caption like “See the menu”, “Get 10% off” or “RSVP here” tells people why to scan, and gets more of them to do it.

Pick a frame, write up to 24 characters, and choose the frame and text colors. Caption ideas for each code type are one click away.

Rules of thumb

Custom, but still scannable

Keep contrast high

Dark code on a light background works everywhere. Light on dark works on most phones; we warn you when contrast is too low.

Logo under 35%

Error correction can rebuild up to 30% of a code. Keep logos small and check the scan result.

Leave the quiet zone

Scanners need a blank margin around the code. Four modules is the standard; don't crop it off in your layout.

FAQ

Questions people ask

Custom QR codes

Will a custom design still scan?

We read your code with a real QR decoder after every change, and only show “Verified” when the result matches what you entered. Shapes and logos raise error correction automatically.

Is it free?

Yes. Every shape, color, frame, logo and template is free with PNG, JPG and WebP downloads. Pro adds vector files, 4096 px and batch.

Can I change the design after printing?

The design is printed, so it can't change. With a dynamic code you can change where it goes, which is usually what matters.

Can I use the files in Illustrator, Figma or Canva?

Yes. SVG, PDF and EPS (Pro) open in design tools and stay sharp at any size. PNG works everywhere.

Can I make the background transparent?

Yes, in the Color tab. PNG, WebP, SVG and PDF keep the transparency; JPG gets a white background.

Do custom codes expire?

Static codes never expire, whatever the design. Dynamic codes work while your plan is active, and your free dynamic code works for good.
