QR Studio

QR codes that can’t be switched off — no redirect, no expiry, any size.

Open QR Studioqr.4brainslabs.com

Most free QR generators route your code through their servers and turn it off when the trial ends. QR Studio puts your content in the code itself, generated in your browser: links, WiFi, contact cards, events, WhatsApp, Google reviews, UPI and SEPA payments and more. Add a logo, colours and a call-to-action frame, test-scan it, and download PNG at any size, SVG, PDF or EPS. It also makes retail and logistics barcodes with the check digits and GS1 sizing done properly.

What it does

  • 16 content types: link, text, vCard, MeCard, WiFi, email, SMS, phone, event, location, WhatsApp, social, Google review, UPI, SEPA, PayPal
  • No redirect service: the code contains your content, so it can never expire or be tracked
  • Shows the exact decoded payload before you download
  • Logo, colours, gradients, dot and eye shapes, frames with call-to-action text
  • In-browser test-scan with an independent decoder, plus contrast, logo-size and print-size warnings
  • PNG at any pixel width up to 16K and beyond; SVG, PDF and EPS vectors
  • Bulk from a spreadsheet, and numbered table menus, as a ZIP
  • Barcodes too: EAN-13, UPC-A, ISBN, Code 128, GS1-128, ITF-14, Data Matrix, PDF417 and more, with check digits and GS1 sizing, plus label-sheet PDFs

Questions

Will the code expire?

No. It contains your content directly; there is no redirect and no subscription. It works for as long as what it points to exists.

Can I edit it after printing?

No static code can. If you may need to change the destination, point it at a page you control and change that page.

Is anything uploaded?

No. The code is generated in your browser and what you type never leaves your device.
