Text QR Code

Any line of text inside the code: an instruction, a serial number, a note. The phone shows it on screen, with no navigation anywhere.

Logo in the center

Frame with caption

Fine tuning

The empty margin around the code is how a scanner finds its edge. Without it, neighboring text or background gets in the frame and the code stops scanning. The standard requires four modules, that is four code cells.

Damage allowance: the code still scans even if part of it is worn, covered by a sticker or smudged. The higher the level, the more space the allowance takes, so with the same data the code grows in modules and each module gets smaller. If a logo is loaded, we set H ourselves: the logo covers part of the code.

The tool is free, with no sign-up and no watermarks. Use the image anywhere, including print and advertising.

When plain text is the right choice

A machine serial number, a product's ingredient list, a batch number, a short instruction posted next to equipment. A person points a camera and reads the text, without opening a browser or using mobile data.

Cyrillic characters take twice the space

A Latin letter takes one byte, a Cyrillic letter takes two. The same text written in Russian produces a denser code than its English equivalent of the same length. On a small sticker the difference shows.

When space is tight, shorten the text or increase the printed size. We show the recommended width for three scanning distances.

Capacity limit

A code holds about three thousand bytes, but pushing that limit is a bad idea: the modules become tiny, and an ordinary camera cannot read them. For long texts, upload the file somewhere and encode the link instead.
