QR Code Generator

Most QR generators are built for screens. This one is built for material. You get a vector .svg sized in real millimetres so it imports into LightBurn or XCS at exactly the size you set, plus a live module-size readout that tells you whether the code is actually engravable before you burn it. Free, unlimited, and it never leaves your browser.

Website address

Going onto a product? This code is static — the address is baked into the artwork and can never be changed. A dynamic code points at a short link you can repoint later, so you can change where it goes after it is engraved. Free, and it takes a moment to set up.

Compact mode — uppercase the domain to shrink the code. Domains are case-insensitive so this is always safe; the path is left alone because paths are not. It only helps on a bare domain.

Presets set every option below. Engraver is the one to use if this code is going onto material.

Error correction

Higher correction survives more damage but makes a bigger code.

Background

Transparent

Scanners read contrast, not colour. Keep the modules much darker than the background, and never invert that relationship. The background applies to PNG, JPG and WEBP — the SVG never carries one, because a filled square is not something you want on a laser bed.

Why engraved QR codes fail to scan

Almost always for one of three reasons. The modules are too small and bleed into each other as the laser cuts, so the scanner can no longer resolve the grid. The quiet zone is missing, because the code was placed hard against a border or the edge of the part. Or the contrast is too low, which is what happens when the engraving and the surface end up too close in tone. The readout catches the first one, every export includes a four-module quiet zone, and the colour controls let you keep the modules clearly darker than the background.

Which error correction level to use

Error correction adds redundant data so a damaged code still reads. Level H recovers from about 30% damage and is the right default for anything engraved, etched or printed on a curved surface, because fill inconsistency and material grain both eat modules. The trade is size: H makes a bigger code for the same content. If you are printing on flat paper, M is usually plenty and gives you a noticeably smaller code.

Keep the content short

Every character you add makes the grid denser, and density is the enemy of engraving. A short link produces a 29 × 29 code, which is comfortable from about 25 mm and still workable down to 15 mm on high-contrast material like acrylic or coated metal. A full contact card can push past 69 × 69, which needs roughly 50 mm before the modules are safe to burn on anything. If a code is coming out too dense, shorten the URL rather than shrinking the artwork.
