QR Code Generator — Free, No Sign-Up

Turn text or a URL into a scannable QR code — download as PNG or SVG.

Runs entirely in your browser — nothing you paste is uploaded or stored.

Customize appearance (colors, logo & label)
Baked into the downloaded image itself, not just shown on this page — useful when printing several codes side by side (e.g. one QR code per payment app) so each one is labeled.

What is qr code generator?

A QR code is a two-dimensional barcode that encodes text — most often a URL — as a grid of black and white squares a camera can read instantly. This tool builds a real, standards-compliant QR code from whatever you type, entirely in your browser, and lets you choose an error correction level and export it as a PNG for sharing or an SVG for print, where a crisp vector matters at any size.

When to use it

  • Linking a printed flyer, business card, or poster to a website without anyone typing a URL by hand.
  • Sharing Wi-Fi details, a contact card, or an app download link at an event or in a physical space.
  • Putting a PayPal, Venmo, or Cash App QR code on an invoice, tip jar, or market stall so people can pay in a tap.
  • Embedding a QR code in a slide deck or document that points to a live page.
  • Testing how a QR code you're about to print actually scans, before committing to a print run.

How to use this tool

  1. Type or paste the text or URL you want encoded.
  2. Choose an error correction level — higher levels tolerate more damage or a logo overlay, at the cost of a denser code.
  3. Preview updates live as you type.
  4. Download as PNG at your chosen resolution, or as SVG for print, where a vector stays sharp at any size.

Example

A QR code encoding this site's homepage URL.

Input

https://devmicrotools.com

Output

A 25x25-module QR code at error correction level M, ready to download as PNG or SVG.

Point any phone camera at the downloaded image to confirm it decodes back to the exact URL that was entered.

Choosing what to encode

A QR code that encodes a full, long URL works, but produces a denser, harder-to-scan pattern than one encoding a short link. If a URL is long — with tracking parameters, for instance — consider generating the code from a shortened version instead.

What generates the code

QR codes are built with qrcode-generator (MIT licensed), a small, open-source library that implements the QR standard’s encoding and error-correction directly. The result is then drawn onto an in-page canvas for the PNG/SVG export — nothing is generated server-side.

Frequently asked questions

What does the error correction level actually control?

It controls how much of the code can be damaged, dirty, or obscured (for example by a logo placed on top) and still scan correctly: roughly 7% at Low, 15% at Medium, 25% at Quartile, and 30% at High. Higher levels add more redundant data, which makes the code physically denser for the same content — Medium is a sensible default for most uses, High if you plan to overlay a logo.

Is there a limit to how much text a QR code can hold?

Yes — this tool caps input at 1,500 characters, comfortably under what the QR standard supports at low error correction, but a QR code storing that much text becomes very dense and harder for cheap cameras to read reliably. For anything beyond a short message, encoding a short URL that points to the full content scans far more reliably.

Why would I choose SVG over PNG?

SVG is a vector format, so it stays perfectly sharp printed at any size — a business card or a building-sized banner both render cleanly from the same file. PNG is a fixed-resolution raster image, better suited to sharing on screen (chat, slides, social posts) where a vector format usually isn't accepted directly.

Does generating a QR code here send my data anywhere?

No. The QR code is built entirely in your browser from a small, open-source encoding library, and the image itself is produced on an in-page canvas. Nothing you type is uploaded, logged, or sent to a server — that's true even for the finished PNG or SVG, which are saved directly from your browser to your device.

My QR code isn't scanning — what's wrong?

The most common cause is insufficient contrast or the code being printed too small for its density — a long URL at Low error correction produces a fine grid that struggles at business-card size. Try a shorter URL (a link shortener helps), a higher error correction level if you're adding a logo, or simply printing it larger.

Which payment apps does the Payment mode support?

PayPal, Venmo, and Cash App — each has a real link format that opens straight into a pre-filled payment screen when scanned, built from just the recipient's username and an optional amount. Apple Pay, Google Pay, and Zelle don't offer any public link format a third party can construct (Zelle's QR codes are generated inside your banking app and tied to your bank enrollment), so they aren't included here. If you already have a Stripe or Square checkout link — a full URL your Stripe or Square dashboard generated for you — use Text/URL mode instead; it's already a plain link and needs no special handling.
