Custom QR Code Generator with Logo, Color and Shape Controls

What is a custom QR code?

A custom QR code keeps the same underlying data pattern as a plain black-and-white code, but changes how it looks: brand colors or a gradient instead of flat black, rounded or circular modules instead of squares, a logo in the center, and an optional frame with a call-to-action label. It is designed to look intentional rather than generic while still scanning reliably.

The studio pairs every visual choice with a live scannability check, since design and readability pull in opposite directions: the more you customize, the more careful you have to be about contrast and how much of the code a logo covers.

How to design a custom QR code

1. Type or paste what the code should hold into the field at the top. The studio works out whether it is a link, WiFi credentials, a contact card or plain text, and the chips underneath correct it if it guesses wrong.
2. This page opens in Design mode already. The Quick and Design buttons above the code switch between the short panel and the full one.
3. Colours is open to start with: set the foreground and background, take one of the palettes, or fill the modules with a curated gradient. Keep the contrast readout at 4.5:1 or better.
4. Open Logo to upload a PNG, JPEG or SVG up to 2 MB, at Small, Medium or Large. It is centred in a cleared pocket, so there is nothing to position, and error correction moves to H and locks while a logo is in place.
5. Open Shapes for the module shape (Square, Rounded or Circle) and the eye shape for the three corner markers (Square, Rounded, Circle, or Rounded with a dot pupil).
6. Open Frame for a label bar above or below the code, or an outline, and write the call to action that sits on it.
7. Watch the scannability meter beside the code as you go, then set the pixel width under Size & error correction and download the PNG, SVG or PDF.

When to use the custom QR code studio

• Brand-consistent marketing: match a QR code's colors and shape to a campaign's visual identity instead of using a generic black-and-white square.
• Product packaging: embed a small logo so the code reads as part of the label design rather than an afterthought sticker.
• Print advertising at scale: design once at high resolution so the code stays sharp on a billboard, magazine page, or storefront window.
• Event and conference branding: apply sponsor or event colors to codes used across signage, badges, and printed programs.
• Agencies designing for clients: produce an on-brand code without a separate graphic design tool.

Tips for custom QR code design

Balance error correction against logo size. A logo covering part of the code removes data that the scanner needs to reconstruct, and higher error correction levels (Q, H) rebuild more of that missing data, but they also make the pattern denser. Keep the logo to 20 to 30 percent of the code area and use the lowest error correction that still passes the scannability check, rather than always maxing it out.

Leave the quiet zone alone: a blank margin of at least four modules on every side of the pattern. Frames and call-to-action text sit outside that margin, and a busy background or a border that touches the modules is a common reason a styled code fails to scan.

Keep contrast ratio at 4.5:1 or higher between foreground and background. Light-on-light or muted brand colors can look fine on screen but fail under poor lighting or when printed on lower-quality paper. If your brand palette is naturally low-contrast, use it for the frame and call-to-action text instead of the QR modules themselves.

A gradient is judged by its palest end, not its average. The studio scores every stop, because the code has to be read where the fade is lightest: a gradient running from deep navy to sky blue fails at the sky-blue end however good the mean looks. The curated gradients clear the threshold at both ends with room to spare, and the eyes stay a flat colour underneath one so the three corner markers keep their full contrast. Build your own and the meter will tell you where it gives out. Under Browse templates, Event, Social and Branded arrive with a gradient already set; the presets meant for small print stay flat, because at business-card size the contrast margin is worth more than the finish.

Test before you print at scale. Print one copy at the actual size you plan to use, then scan it with two or three different phones in normal lighting. A design that looks fine at full size on a monitor can fail once it is shrunk down to fit a business card or product label.

For a simpler, single-purpose code without the full design studio, use the URL QR code generator or the WiFi QR code generator. To make many codes at once, the bulk QR code generator takes a CSV and carries its own template gallery; a design built here does not travel across to it.
