Saved QR Codes
Save QR-code payloads by name for quick reuse.
Overview
The Saved QR Codes tool lets you bookmark QR payloads by name for quick reuse — your Wi-Fi credentials, a vCard, a recurring meeting link or a "scan to pay" code — so you do not have to retype the source string each time. Saved entries persist in your browser, render instantly and re-encode on demand at any size.
The tool is aimed at small-business owners rotating display QR codes, IT admins handing out network credentials, event organisers managing multiple check-in codes and anyone with a small collection of QR codes they reach for repeatedly. Long-tail searches like "save qr code for reuse", "qr code bookmark manager" and "store wifi qr offline" all resolve here.
How it works
Each saved entry is { name, payload, format } stored in your browser's local storage as JSON. The tool re-renders the QR image on demand using a standard QR encoder that supports the four common payload types: plain text, URL, Wi-Fi (WIFI:T:WPA;S:...;P:...;;) and vCard 3.0. Error correction level is configurable between L (low) and H (high); higher correction lets the code survive partial damage at the cost of denser modules.
Because storage is local, no payload ever leaves your device. The QR image itself is rendered to a <canvas> and exported as PNG or SVG so you can drop it into a slide deck, print it on a sticker or copy it as a data URI. There is no cloud sync — exporting and re-importing the JSON list is the way to move entries between devices.
Examples
Save "Office Wi-Fi" → WIFI:T:WPA;S:CompanyNet;P:correct-horse;;
Save "Meeting link" → https://example.com/standup
Save "My vCard" → BEGIN:VCARD ... END:VCARD
Export → JSON snapshot of all saved entries
FAQ
Where is the data stored?
In your browser's local storage. Nothing is sent to a server. Clearing site data removes all saved entries.
Can I sync across devices?
There is no built-in sync. Export the JSON list and import it on the other device — manual but private.
What error-correction level should I pick?
Use M for screen display, Q or H for printed codes that may suffer wear. Higher correction means a denser, slightly larger code.
Does it support coloured QR codes?
Yes. Set foreground and background colours, but keep contrast high so scanners still read reliably.
What is the max payload size?
Up to about 4,200 alphanumeric characters or 2,900 bytes at low correction. Larger payloads need a higher-version QR code, which produces a denser image.
