QR code

Generators

Generate a QR code with custom size, error correction, and colors. Download SVG or PNG.

What this tool helps with

A QR code encodes any short string — usually a URL, but also Wi-Fi credentials, plain text, or vCards — into a square matrix readable by phone cameras. Capacity depends on the data type and error-correction level; URLs of typical length fit comfortably with high correction so the code stays scannable on stickers and screens. This generator renders the code as SVG so it scales without blurring and lets you adjust size and error-correction, all in the browser without uploading the destination URL anywhere.

How to use QR code

  1. Open the QR code page and paste, type, or generate the qr input you want to work with.
  2. Pick the options you need so the tool can generate a QR code with custom size, error correction, and colors. Download SVG or PNG
  3. Copy the code result with one click and use it in your next step — terminal, editor, ticket, or anywhere else you need it.

Common uses

  • Reach for QR code when you need to generate a QR code with custom size, error correction, and colors. Download SVG or PNG during debugging, code review, or content preparation.
  • Skip installing a desktop qr app — open this generators utility on a shared machine, an iPad, or a colleague's laptop and it just works.
  • Bookmark or share the page when you and your team keep coming back to the same qr, code, qrcode, and barcode workflow.

FAQ

Which error-correction level should I pick?

L (7%) is fine for clean digital displays. Q (25%) or H (30%) for printed codes that might be partially obscured by a logo, scratched, or photographed off-angle. Higher correction makes the code denser but more robust.

Is there a limit on URL length?

Practically yes — a long URL forces a denser code that becomes harder to scan from a distance. Aim for under 100 characters when possible; for longer URLs use a short link first.

Why an SVG instead of a PNG?

SVG QR codes scale crisply at any size, embed cleanly into print artwork, and stay small. Convert to PNG only when a system specifically requires a raster image.
