QR Code Generator

What a QR code actually contains

A QR code stores information in a two-dimensional pattern of dark and light squares. A reader uses the position markers to locate the symbol, then decodes its cells. This generator makes static codes: your content is embedded directly in the image, with no RizeTab redirect or managed short link in between.

A website link and a text message behave differently

Enter a complete https:// address when you want a scanner to offer to open a website. Plain text usually appears as a message in the scanning app. A link to an event schedule can open the current schedule online; “Meeting room: third floor” simply conveys that instruction. The generator preserves the text you enter, including spaces at the beginning and end.

Create, scan, then download

Enter your content, choose the PNG size and error correction level, and select Generate QR / Generate again. Scan the preview before distributing it: check the destination domain, spelling, and any non-English characters. Download PNG saves the image locally. Editing the text or settings removes the previous preview so you cannot accidentally download an outdated result.

Practical uses for a static code

Use a QR code on a menu, a product label pointing to instructions, or a poster linking to event registration. Add a readable description or address alongside it for people who cannot scan. A printed code cannot be edited. You can update the web page at the same address, but replacing the encoded address requires a new code and a new print.

Make the printed version easy to scan

The image uses black squares on white, with a clear border at least four modules wide. Keep that border intact and avoid placing artwork over the symbol. Downloads are 256, 512, or 1024 pixels square; cells align to whole pixels to keep their edges sharp. Longer content needs more cells, so the smallest size may be unsuitable. There is no universal print dimension: density, viewing distance, paper, and printer quality all matter. Print a sample at its final size and test it with several phones from the intended distance.

Choosing an error correction level

M, Q, and H add progressively more recovery information, which can help a reader recover data from a partially damaged symbol. More recovery information can also make the code denser. Start with M for a clean screen display; consider Q or H for a label exposed to wear. Error correction cannot guarantee a scan when the image is blurry, low-contrast, or missing important position markers.

Local processing is useful, but a QR code is public

The QR module processes your input in this browser without sending it to RizeTab or a third-party QR service. Existing page resources, including advertising, fonts, and analytics when permitted, can still make network requests. QR encoding is not encryption: anyone with the image can read its contents. Avoid embedding passwords, access tokens, or private personal information. Sharing the downloaded PNG also shares the data inside it.
