Free embed widget
A free QR code generator on your own website
Your readers build a WiFi, menu, contact or link code and download it as PNG or SVG — without leaving your page, without an account, and without a watermark.

Each type has its own form, so nobody has to know how a WiFi or vCard string is actually written. They fill in the fields and the code appears.
Link
Any URL
WiFi
Network, password, security type
Contact card
vCard — name, phone, company
Address, subject, body
Phone
Tap to call
SMS & WhatsApp
Prefilled message
Location
Coordinates from a map
Calendar event
Title, place, start and end
Crypto
Payment address
Plain text
Anything else
Who puts a QR generator on their site
An article about QR menus that then sends the reader off to find a generator has done half the job. This finishes it on your page.
Restaurant and hospitality sites
Menus, WiFi for guests, review links and table ordering. A supplier blog that lets a restaurant owner build the code on the page is far more useful than one that tells them to go find a generator.
Event and wedding sites
Invitations, seating plans, shared photo albums, gift lists. Everything at an event ends up behind a code, and the person planning it is on your page right now.
Churches and community organisations
Giving links, bulletins, sign-up forms. Codes are printed once and handed to hundreds of people, and almost every generator that lets you change them later charges for it.
Retail, schools and small business
Shelf labels, classroom handouts, business cards, guest WiFi. Short jobs that nobody wants to sign up for a service to finish.
Nothing to run
The matrix, the PNG and the SVG are all built in the reader’s browser. No server of ours renders an image per visitor, so there is no bill, no API key and no rate limit however busy the page gets.
Fully styleable
Colours, linear and radial gradients, a logo in the centre, transparent background, error-correction level. The same editor as on our own site, not a trimmed-down one.
No watermark, no expiry
A static code made in the frame belongs to whoever made it, keeps working forever and is not tracked. Nothing to sign up for, on either side.
About two minutes
Adding it to your site
Pick the QR generator
It is at the top of the widget list, above the calculators.
Set language and theme
Ten interface languages, light or dark, or follow the reader’s own system setting.
Paste the snippet
Into an HTML or embed element. That is the whole installation.
On platforms that strip scripts (some hosted builders do), the generator still works — only the automatic height adjustment stops, so the frame keeps the height written in the snippet. Set that height yourself and nothing is lost.
Works in the widget
- Every code type — link, WiFi, vCard, email, phone, SMS, WhatsApp, location, event, crypto, plain text.
- All styling: colours, gradients, centre logo, transparent background, error correction.
- Download as print-ready PNG or vector SVG.
- Ten interface languages, light and dark themes.
Does not, and why
- Dynamic, editable, trackable codes. A dynamic code is a short link we host and somebody has to own it, which needs an account — so inside the frame that option links out to the full generator instead of pretending to work.
- Removing the credit link. It is what the widget is exchanged for, and the wording is the same for every site — per-site keyword links would turn this into something search engines penalise us both for.
Wondering how the generator itself compares with QRCode Monkey, Canva and the rest? That comparison lives here.
