QR Code Generator
This generator builds a byte-mode QR code at error correction level M, versions 1 to 4. A 4-module quiet zone is drawn around the matrix. The field starts as https://yourhack.ai.
Runs in your browser. Nothing you enter is uploaded.

Past 62 bytes the status says the text is too long and no new code is drawn. Mask 0 is the only mask. The download file name is qrcode.png.
Create a real, scannable QR code from any link or text in a single step. QR codes are the fastest way to bridge print and screen, sending someone from a poster, business card, menu or slide straight to a URL without typing. This generator encodes your input fully in your browser using a proper QR algorithm, so the code you see is the code any phone camera will read, not a picture that only sometimes works. Type your text, watch the code render live, and download it as a crisp PNG for printing or embedding. Because everything runs locally, the content you encode is never sent to a server, which matters when the link itself is private.
How to use QR Code Generator
- Enter the URL or text to encode.
- Wait for the QR code to render.
- Scan it to confirm it works.
- Download it as a PNG.
Frequently asked questions
What QR does https://yourhack.ai make?
Version 2, 25 by 25 modules, saved as a 264 by 264 PNG with a 4-module white border.
How long can the text be?
62 bytes. ASCII is one byte per character. Characters outside ASCII take more than one byte, so the character count can be lower.
Is the link uploaded to make the code?
No. The matrix is drawn on a canvas in the browser.
