About QR Code Tools
QR codes are the fastest way to hand off a URL, a WiFi password, a contact card, or a calendar invite from one screen to another without typing. FormatFuse bundles both sides of that workflow: a generator that turns your input into a customizable PNG or SVG, and a reader that decodes QR codes from images, screenshots, and photos — both running entirely in your browser.
Neither tool uploads anything. When you generate a WiFi handoff code for the office, the password stays on your machine. When you decode a QR from a screenshot, the image never touches a server. This matters because QR content is often sensitive: credentials, personal contact information, payment links. Browser-only processing removes the "someone else's server has my data" failure mode entirely.
Pick the generator if you need to create a QR code for a poster, menu, business card, or event. Pick the reader if you already have a QR image and want to see what it encodes before scanning it with a real device. Both tools support the full range of QR payloads — URLs, WiFi, vCards, SMS, mailto, geo pins, calendar events, and free text — so you rarely need a different tool for a different use case.
QR Code Tools — Frequently Asked Questions
Should I use the generator or the reader?
Use the generator to create a QR code from text, a URL, WiFi credentials, or a contact record. Use the reader to decode a QR code from an image, screenshot, or photo. Most people need the generator; the reader is useful for screenshots, printed codes photographed remotely, or auditing what a QR actually encodes before trusting it.
Do I need an account?
No. Both tools work entirely in your browser with no signup, no API key, and no login. There is also no usage quota — generate or decode as many codes as you need.
Are the QR codes free for commercial use?
Yes. QR code specifications are in the public domain (ISO/IEC 18004), and FormatFuse doesn't add any watermark, tracking pixel, or usage restriction to the codes you generate. Print them on menus, packaging, business cards, and signage without attribution.
What's the maximum amount of data a QR code can hold?
Up to about 4,200 alphanumeric characters, but practical codes hold far less — most URLs are under 100 characters. More data means a denser code, which needs a higher camera resolution to scan reliably. If your content is long, shorten the URL or link to a page rather than embedding the full text.
