QR code generator for small business

Yes. Every code you make here is free to use commercially, with no watermark, no account and no expiry. You own what you download.

No. A QR code is just a printed pattern that contains your link — there is no subscription behind it. It keeps working as long as the destination link works. Because of that, point your code at a URL you control rather than one you might lose access to.

Yes, that is what most people use it for. In your Google Business Profile, open Ask for reviews and copy the short link (it looks like https://g.page/r/…/review). Paste it here and your code will open the review form directly. You can also paste your Place ID instead.

Yes. Choose Share Wi-Fi, enter the network name, password and security type. Phones running iOS 11+ and Android 10+ join the network from the camera app. The password is encoded into the printed pattern, so only print it where you would be comfortable writing the password down.

Yes. Download the SVG for signs, window decals and anything large — it stays sharp at any size. Use the 2048 px or 4096 px PNG for print shops that ask for raster files. As a rule of thumb, keep the printed code at least 1 inch (2.5 cm) wide for close-range scanning, and about 1/10th of the scanning distance for signs across a room.

Dark code on a light background, with strong contrast. Scanners look for a light-to-dark difference, so a near-black code on white is the safest choice. Avoid light-on-dark (inverted) codes, low-contrast pastel pairs, and busy background images. This tool measures the contrast ratio for you and warns you before you download.

Yes. When you add a logo or emoji, error correction is automatically raised to level H, which lets the code survive up to about 30% damage. Keep the center image under roughly 16% of the code area — above that the data becomes unrecoverable and the warning turns red.

Yes. The code is generated entirely inside your browser using JavaScript. Your links, Wi-Fi passwords and logo files never leave your device and are never sent to a server, because there is no server involved in generating them.

Yes. Open the 3D object tab and choose a table stand, a keychain with a ring hole, or a wall sign. You pick two colors — one for the base, one for the raised code and text — and download a 3MF that already carries both. The code is built from real raised geometry, not an engraved picture, so it has physical relief and genuine color contrast.

3MF is the modern replacement for STL. Where an STL is just a bag of triangles, a 3MF is a small package that also stores units, colors and materials. That is why we use it as the main format: your slicer opens the file with the base and the raised code already assigned to different colors, instead of you having to paint them by hand.

STL stores geometry and nothing else — no colors, no units, no material assignment. 3MF stores all of that inside the file. Use the 3MF if your slicer supports it (Bambu Studio, OrcaSlicer, PrusaSlicer and Cura all do). Use the STL only if you are on older software; you will get the same shape in a single color.

It will if the modules are big enough and the two colors contrast. A 0.4 mm nozzle cannot hold detail below roughly 1.2 mm per module, so the tool measures the module size for your exact link and refuses to export below that instead of letting you waste filament. Longer links need bigger objects: a short g.page/r/…/review link fits on a 45 mm keychain, while the long writereview?placeid=… URL does not.

Print the base and the code in colors that actually differ in lightness — dark base, light code, or the reverse. A grey-on-grey object is geometrically perfect and completely unscannable.

The table stand is the one most businesses want: it sits on a counter at a readable angle and prints without supports. The keychain works for events and giveaways, but keep the link short so the code stays large enough. The wall sign is a flat plate with four mounting holes for doors, reception desks and windows.

PNG is made of pixels — fine for screens and for print shops that request a high-resolution image. SVG is vector maths, so it can be scaled to a billboard without a single soft edge. If your printer accepts SVG, use SVG.
