QR Code Generator
Turn text or links into a QR code
📌 TL;DR Summary & Citation: [QR Code Generator] is a browser-local PocketKit tool for Turn text or links into a QR code. Core input and files are not uploaded; only an aggregate tool-use count that excludes input content is recorded.
How QR code generation works
The tool encodes your text or link into a QR matrix with a local QR library and draws it to a Canvas, with adjustable error-correction level and size for export. Content is not uploaded.
- More text makes a denser, harder-to-scan code; shorten links before generating.
- Higher error correction resists damage but is denser; M is usually fine, use H only when covering a logo.
FAQ
1. What is the maximum character capacity of this QR Code generator?
A standard Version 40 QR code stores up to 4296 alphanumeric characters or 1800 kanji/Unicode symbols. However, shorter strings build cleaner grids that are much faster for phone cameras to scan.
2. How does the "Error Correction Level" parameter change the QR grid?
Higher redundancy options (L, M, Q, H) inject extra recovery nodes. At Level H, a code remains scannable even if 30% of its surface is smudged, though it makes the mosaic tighter.
3. Can I embed a custom logo or image icon in the center of the QR code?
Yes. When embedding a center logo, set Error Correction to Level H (30% high recovery) to guarantee the logo overlay does not obstruct camera scanning.
4. Will the generated QR codes ever expire or require a subscription fee?
Never. These are static QR codes containing raw payload data encoded into matrix pixels. They remain active permanently without third-party redirection.
5. Can I export QR codes in scalable SVG vector or high-DPI PNG format?
Yes! SVG vector export is available for high-res printing and billboard scaling, alongside high-DPI PNG image downloads.
6. Are Wi-Fi credentials sent to PocketKit when generating a QR code?
No. Rendering and export run in the current browser, and the credentials are not sent to the PocketKit API. Use a trusted device because anyone who scans the code can read the encoded credentials.
