What is QartText?
QartText is a browser-based QR code generator that embeds readable text or typography directly into fully-scannable QR codes. It works entirely offline and uses linear algebra over GF(2) to compose the payload with artistic text placement, leaving the error-correction budget intact for real-world durability.

QartText pros
- Generates fully functional, scannable QR codes with embedded text—no damage to error correction
- Works entirely offline in the browser; installable as a home screen app with no network dependency
- Multiple error correction levels (L/M/Q/H) and symbol sizes (Micro, Pixel, Mixed) to balance text legibility and code readability
- Fine-grained control over text placement, clearance, and contrast; exports as PNG or SVG
QartText cons
- Text readability is severely limited by QR code structure—small symbol sizes (3x5 to 5x8) make text difficult to read at typical scales
- Manual trial-and-error required to find optimal clearance and placement for specific content
- Placement flexibility is constrained where modules carry payload bits, limiting artistic freedom
Frequently asked questions about QartText
Does QartText require an internet connection?
No. QartText runs entirely in your browser and never sends data anywhere. It works fully offline after the initial load and can be installed as a home screen app.
Will the QR code still scan if it contains text?
Yes. QartText uses Gauss–Jordan elimination to find free bits in the QR code's padding and uses those bits to render the text, leaving the error-correction budget completely intact.
What are the smallest text sizes available?
Micro (3×5 pixels), Pixel (5×7), and Mixed (5×8) are the available options; each requires different symbol sizes to print legibly.
