QR Code Generator

Make a permanent, never-expires QR code — URL, Wi-Fi, contact & more. Static PNG + SVG you fully own, built in your browser.

If you leave out https:// we'll add it so phones open it as a link.

Blank margin around the code, in modules. ISO minimum is 4; we allow 4–16.

Higher = sharper print. 10 ≈ 300+ DPI at typical sizes.

Used for the print-size advisory (10:1 rule).

QR Code Generator — guide & how to use

What it does

This free QR code generator builds a static QR code right in your browser and renders it live. Pick what the code should do — open a link, join a Wi-Fi network, save a contact, send an email or text, call a number, or open a map — fill in the fields, and download a permanent PNG or SVG you fully own. Because the data is encoded directly into the image (per ISO/IEC 18004), there's no server, no account, and nothing that can expire.

How to use it

  1. Choose what the QR code should do and enter the relevant fields.
  2. Pick an error-correction level (M is a good default; Q/H if you'll add a logo or print rough).
  3. Optionally set colors, PNG pixels per module, and your scan distance for the print advisory.
  4. Download the PNG (screens / quick print) or the SVG (signage / large print — stays razor sharp).
  5. Test the scan on the phones you care about before printing in bulk.

Static vs dynamic codes — read this first

This tool makes static codes only: the destination is encoded permanently into the image and cannot be edited later. That is the feature — the code never breaks and needs no account — but it means changing a URL requires generating a new code. Static codes also cannot track scans or show analytics. If you genuinely need an editable destination or scan counts, a static code is the wrong tool and you should use a dynamic-code service instead. We'd rather tell you that than upsell you.

Minimum print size (the 10:1 rule)

Make the code at least 1/10th of the farthest distance it'll be scanned from: 30 cm away → ~3 cm code; 3 m away → ~30 cm code. The absolute floor for any printed code is about 2 cm (20 mm) — below that, modules blur together and close scanning gets unreliable. The 10:1 rule is a field guideline, not part of ISO/IEC 18004: real minimum size also depends on camera quality, lighting, and contrast, so treat it as a floor, not a promise. For anything large, export the SVG so it scales with zero blur — never blow up a small PNG for a banner.

Quiet-zone rules

QR codes need a blank border — the quiet zone — so a scanner can find them. ISO/IEC 18004 sets the minimum at 4 modules on all sides, and this tool clamps the margin to 4 if you try to go lower. Cropping or styling away the quiet zone to make a code "fit" a design is the single most common cause of codes that won't scan.

Error-correction levels

Error correction adds redundancy so the code still scans when smudged, printed small, or partly covered: L ≈ 7%, M ≈ 15%, Q ≈ 25%, H ≈ 30% of codewords recoverable (fixed by the standard). Higher correction tolerates more damage but makes the code denser for the same data. If you place a logo over the center, bump to Q or H — but note even H can fail if the overlay covers more than ~25–30% of the area, and concentrated damage over the finder patterns (the three corner squares) kills any code regardless of level.

Frequently asked questions

Will this code expire or stop working?

No. It's static — the data lives in the image itself, with no server or redirect. It works forever. The trade-off is you can't edit where it points; that needs a new code.

Is my Wi-Fi password / contact info sent anywhere?

No. Everything is encoded in your browser. Nothing is uploaded, logged, or stored.

PNG or SVG — which should I download?

PNG for screens and quick print. SVG for large print (signage, billboards) — it's vector, so it stays sharp at any size.

Why did it reject my input?

A single QR code has a hard capacity limit (Version 40). If your text exceeds it, we refuse to encode rather than silently truncate it — a cut-off URL still "scans" but goes nowhere. Shorten the data or lower the error-correction level.
