Sharing Wi-Fi with guests
A Wi-Fi code lets visitors join by scanning it, with no password to read out or mistype. Print one for the fridge, the guest room or the café counter.

The guide
QR codes, explained
Everything you need to know about making QR codes that scan first time.
Why Use This Tool?
A QR code turns a link, a Wi-Fi login or a set of contact details into a pattern that any phone camera can read in a second. It saves people from typing long addresses, mistyping passwords or hunting for your number — and it works as well on a screen as on paper.
This free QR code generator builds the code right in your browser. There's no sign-up, no watermark, no expiry date and no limit on how many codes you make. Choose your colours, add a logo if you like, and download a PNG or a print-ready SVG.
Popular Uses
QR codes are useful anywhere someone needs to get from the physical world to a screen, or to receive something without having it spelled out.
Menus, flyers and posters
Link a printed menu, event page or sign-up form to a single scan. Use the SVG download so the code stays sharp on anything from a table tent to a banner.
Business cards and contact details
A contact code saves your name, number, email and website straight into someone's address book — no retyping and no typos.
Examples
Every QR code is just text in a format that phones know how to act on. These are the formats this tool creates.
| Type | Encoded as | What a phone offers to do |
|---|---|---|
| Link | https://example.com | Open the page |
| Wi-Fi | WIFI:T:WPA;S:HomeNet;P:secret;; | Join the network |
| Contact | BEGIN:VCARD … END:VCARD | Save the contact |
mailto:hi@example.com?subject=Hello | Start a draft email | |
| SMS | SMSTO:+15550100199:Hi there | Start a text message |
| Phone | tel:+15550100199 | Place the call |
Exact behaviour varies a little between phones and camera apps, so scan the finished code on the devices your audience is likely to use before you print it.
How to Make a QR Code
- Pick a content type — link or text, Wi-Fi, contact, email, SMS or phone — and fill in the details.
- Choose colours, module shape, size and error correction, or leave the defaults, which work for most uses.
- Check the preview, scan it with your phone, then press Download PNG or Download SVG.
Complete Guide to QR Codes
A few ideas explain most of what makes a QR code easy to scan.
Static vs. dynamic codes
A static code stores your content inside the pattern itself. It can't be edited later, but it never expires and doesn't depend on anyone's server. A dynamic code stores a short redirect link instead, so the destination can change and scans can be counted, usually through a paid service. Everything this tool makes is static.
Error correction
QR codes carry extra data so they can still be read when part of the pattern is dirty, scuffed or covered. Level L recovers about 7% of the code, M about 15%, Q about 25% and H about 30%. Higher levels are sturdier but make the pattern denser, so they need more room.
Quiet zone and size
The blank margin around a code, called the quiet zone, helps scanners find its edges. The standard asks for at least four modules (the small squares) on every side, which is why the margin defaults to 4. For close-range scanning, print the code at least about 2 cm wide.
Contrast and colour
Scanners look for dark modules on a lighter background. Dark on light with strong contrast is the safest choice; light-on-dark and low-contrast pairs work on some phones and fail on others.
How This Tool Works
Your content is converted to bytes, split into blocks and protected with Reed–Solomon error-correction codes. The bits are laid out in a grid alongside the fixed finder, timing and alignment patterns, and one of eight mask patterns is chosen to keep the result easy to scan. The finished grid is drawn on a canvas for the PNG and written out as vector paths for the SVG, all inside your browser.
Tips & Best Practices
- Test every code with at least two phones before you print or publish it.
- Shorter content makes a simpler, easier-to-scan code. Link to a short page on your own site instead of pasting a long address full of tracking parameters.
- Keep strong contrast: a dark foreground on a light background is the safest pairing.
- If you add a logo, keep it small. The tool sets error correction to High automatically, but the code still needs to be scanned once to be sure.
- Use SVG for print and PNG for screens, and export larger than you think you need. You can always scale a big PNG down but not up.
- Leave the margin at 4 modules unless space forces you to shrink it.
Limitations & Privacy
Privacy
Everything happens in your browser. The text, Wi-Fi password, contact details and logo you enter are never uploaded, and the finished code is drawn on your own device. With no server in the middle, nobody can see or count your scans. Keep in mind that anyone who scans a Wi-Fi or contact code can read what's inside it.
Limitations
These are static codes, so you can't edit one after printing it or see how often it's scanned. A single code holds at most about 2,950 characters of plain text, and far less at higher error-correction levels; accented letters, emoji and non-Latin scripts use two to four bytes each. This tool creates codes — it doesn't scan them.
