About the QR code generator
A QR code turns a link or a piece of text into a square a phone camera reads in a second. This generator builds one from any URL, message, or plain text and lets you download it as a PNG for slides and social posts, or an SVG that stays sharp at any print size.
Codes are generated in your browser, so what you type is never sent to a server, and the code encodes your link directly — no shortener, no redirect, no tracking in between. Change the color, pick a module shape, or drop a logo in the middle, then download. Free and unlimited, with no account.
How to make a QR code
- 1
Paste your link or text
Any URL, message, or plain text. The preview redraws as you type.
- 2
Style it
Pick a color and module shape, and add a logo in the centre if the code should carry your brand.
- 3
Download PNG or SVG
PNG for screens and slides, SVG for print and large formats — both scale without blurring.
What the generator does
Live preview
The code redraws on every keystroke, so you can scan-test it before you download.
Color, shape, and logo
Match your brand with a custom color, rounded or dotted modules, and a centre logo.
PNG and SVG
Raster for screens, vector for print — the SVG stays crisp on a poster or a card.
Generated in your browser
Your link is encoded locally. Nothing is uploaded, logged, or tracked.
No expiry, no redirect
The URL is encoded directly, so the code can't break when a shortener disappears.
