About
QRLens is a complete QR code workspace for your desktop. Grab a code straight off your screen, read one out of an image file, and create your own codes — all in a single window, and all without sending anything over the internet. Most QR tools ask you to point a phone at your monitor or upload a picture to a website. QRLens removes both steps. The code is already on your screen or in a file on your PC, so it makes sense to read it right there. WHAT YOU CAN DO Scan any part of your screen Capture your screen and drag a box around a QR code in a video call, a PDF, a chat window, a slide deck, or a web page. No second device, no photographing your own monitor. Read codes from image files Open a PNG, JPG, WebP, or HEIC file and QRLens finds the code inside it. Useful for screenshots, scanned documents, and photos sent to you by someone else. Generate your own codes Turn a link, a message, contact details, an email address, a location, or Wi-Fi credentials into a QR code. Adjust it to suit where it will be used, preview it as you go, and save the finished code as a PNG for everyday use or an SVG for print and large formats. Keep a searchable history Every scan is stored locally so you can find it again. Search across everything you have scanned, star the codes you keep coming back to, open a saved result in one click, and delete individual entries or clear the whole history whenever you want. Understand what you scanned QRLens recognizes what a code actually contains — a web link, a Wi-Fi network, a contact card, an email address, a location, or plain text — and presents it accordingly, so you can act on it instead of staring at raw text. BUILT TO STAY ON YOUR PC There is no account to create and no sign-in. Screen captures and opened images are processed in memory on your machine and are never uploaded or stored as images. Only the decoded text and a small amount of result information are written to a local database in your user folder. Your scan history is yours alone: it is not synchronized, not backed up to a server, and not visible to anyone else. Because everything runs locally, QRLens also works with no internet connection at all. MADE FOR EVERYDAY USE Available in English, Simplified Chinese, Traditional Chinese, Japanese, Korean, French, German, Spanish, and Italian, with a calm dark interface that stays out of the way. Switch languages at any time and the whole app follows immediately. Whether you are checking a link before you trust it, joining a Wi-Fi network from a printed card, pulling a ticket code out of a screenshot, or producing codes for a menu, a label, or an event, QRLens keeps the whole task in one place.
