Most online generators quietly point your code at their own short link. That gives them a scan counter — and gives you a code that can break the day their free tier ends, their domain lapses, or they decide the good export formats are a paid feature. QR Studio takes the opposite approach: the data is encoded straight into the pattern, on your machine.
Online generator
Your URL is wrapped in their short link. Scans are logged, the code can expire or be redirected, high-resolution and vector export sit behind a subscription, and whatever you typed — a Wi-Fi password, a phone number — was uploaded to a server you don't control.
QR Studio
The code is static: the data lives in the pattern itself, so it works forever and nobody counts the scans. Generation happens in your browser with no network request, and every export format — including 2048px PNG and vector SVG — is free.
Features
Everything other tools charge for — logos, vectors, HD export, scanning — built in and free, because none of it costs us a server.
Drop in a logo, switch the foreground to a linear or radial gradient, choose from six dot shapes and separate corner-eye styles, set the error-correction level, and wrap the whole thing in a frame with your own call-to-action text. When a logo is added the error correction is raised automatically so the code still scans.
URL, plain text, Wi-Fi network, vCard contact, pre-filled email, SMS, phone number, map location, calendar event, crypto payment address, smart app-store link and social profiles. Each one has proper fields, so you never have to remember the encoding format yourself.
PNG, SVG, JPG and PDF, at any size up to 2048px, or straight to the clipboard. SVG stays sharp at billboard size; transparent backgrounds are one checkbox away.
Decode from an image file, a drag-and-drop, a clipboard paste, a capture of the whole page, or by right-clicking any image you see. Reads QR plus common 1D and 2D barcodes, and parses the result into something you can act on.
Every code you make or scan is kept locally, searchable, taggable and starrable. Save a style you like as a template and reuse it in one click. Back everything up to a JSON file and restore it on another machine.
Alt+Shift+Q opens QR Studio with the current page pre-filled; Alt+Shift+S jumps straight to the scanner. The right-click menu covers the page, a link, selected text, or an image to decode.
No sign-up, no network requests, no analytics SDK, no remote API. Install it, turn off your Wi-Fi, and everything still works exactly the same.
Data types
Pick a type, fill in the fields, and QR Studio builds the correctly formatted payload for you.
URL
Link to any website or page, pre-filled from the tab you are on.
Text
Encode any plain text — a serial number, a note, a passphrase.
Wi-Fi
Guests join your network by scanning, without you reading the password out loud.
Contact (vCard)
A contact card with name, company, phone, email and address that saves in one tap.
Opens a new message with the recipient, subject and body already filled in.
SMS
Opens a text message to a number with your wording ready to send.
Phone
Tap to call a number — useful on posters, vehicles and shop windows.
Location
Drops a pin at exact coordinates in the phone's default map app.
Calendar event
Adds a titled event with time and place to the calendar in one scan.
Crypto
A Bitcoin, Ethereum or Litecoin payment address, with an optional amount.
App link
One code that sends iOS to the App Store and Android to Google Play.
Social
WhatsApp, Telegram, X, Facebook or LinkedIn — from a handle or number.
Every type exports to all four formats, at any size up to 2048px:
Screenshots
Three surfaces: the toolbar popup for speed, the editor for control, and the tools hub for everything else.
Open the popup and the current tab is a QR code before you've typed anything. Download it as PNG, SVG, JPG or PDF, copy it to the clipboard, or send it into the editor to style it properly.
Twelve data types across the top, the live preview beside them. Flip to the Style tab for logo, gradient, dot and corner shapes, size, margin, error correction and the frame label — the preview updates as you go.
All twelve generators plus the scanning and management tools: scan an image or file, paste from the clipboard, browse and re-download your history, and set your default style, theme and backups.
Permissions
QR Studio asks for no host permissions and no camera access. Here is exactly what each permission is used for.
| Permission | What it is used for |
|---|---|
| activeTab | Reads the current tab's URL — only while the popup is open — so the QR code for the page you're on is ready immediately. It is also what lets the visible tab be captured when you choose full-page scanning. |
| contextMenus | Adds the right-click entries: make a QR code for this page, this link or the text you selected, and scan a QR code inside an image you right-clicked. |
| storage | Saves your history, style templates and settings in the browser's local extension storage so they survive a restart. |
| unlimitedStorage | Raises the size limit on that same local storage. QR thumbnails and embedded logos are images, and the default quota fills up fast; this grants no extra access, only more room. |
| scripting | Shows a small overlay with the decoded value after you scan an image from the right-click menu. Injected only into the tab you acted on, only at that moment. |
No host permissions, no tabs permission, no camera. The extension makes no network requests at all, so there is no remote code to audit and nothing to switch off.
This isn't a policy promise about how carefully we handle your data — there is no server for your data to reach. Wi-Fi passwords, contact cards and crypto addresses are encoded by JavaScript running in your own browser, and the result never leaves it.
