QR Code Generator
Turn a web link into a QR code you can embed or share.
QR Code Generator
What does it do?
The QR Code Generator node turns a web link into a scannable QR code. Think of it like printing a shortcut button that someone can scan with their phone.
Use it when you want to share landing pages, checkout links, event pages, or product pages faster.
Smart features
Checks the link before creating the QR code: Diaflow only generates a QR code for valid web links.
Works with dynamic values: insert a link from an earlier step with @.
Lets you choose how the result is returned: use Image to embed the QR code directly, or Link to get a shareable file link.
Supports PNG and SVG: choose PNG for simple image use, or SVG for sharper scaling.
Includes ready-to-use size options: pick 128px, 256px, 512px, or 1024px.
Lets you control the look: set the background color, foreground color, border, and scan durability level.
Supports transparent SVG backgrounds: useful when the QR code needs to sit cleanly on branded designs.

Real-World Business Value
Add a QR code to event emails so attendees can open the registration page instantly.
Generate product or payment QR codes from live links created earlier in the workflow.
Create branded QR codes for flyers, packaging, or printed handouts without manual design work.
Step-by-Step Setup
Drag QR Code Generator onto the canvas.
In Input, enter the full web link or select one from an earlier step with @.
In Output Size, select 128px, 256px, 512px, or 1024px.
In Background Color, enter a color like
#FFFFFFor choose transparent if you use SVG.In Foreground Color, enter the QR code color, such as
#000000.In Output Format, choose PNG or SVG.
In Output Type, choose Image if another step should use the QR code directly, or choose Link if you want a downloadable file link.
In Border Width, keep the default unless you have a specific design need.
In Error Correction, choose a higher level if the QR code may be printed, handled often, or partially covered.
The Transformation: Before & After
Before link and display settings entering the node

After ready-to-use QR code result

If you choose Image instead of Link, the result is returned as an inline image value you can place directly into emails or pages.
Tips & Warnings for First-Timers
Best practices
Paste the full web link, including
http://orhttps://.Use SVG for print designs or large displays.
Use a higher Error Correction level when the QR code may be scratched, folded, or partly covered.
Use Image when the next step should embed the QR code directly.
Use Link when you need a file you can share, store, or reuse elsewhere.
Warnings
Do not enter plain text, email addresses, phone numbers, or non-web formats. This node only accepts web links.
Do not leave out
http://orhttps://. A link without the protocol will fail.Do not use transparent as the background for PNG. Use it only with SVG.
Do not expect the same settings to reuse an older file automatically. A new QR code is created each time.
Do not rely on Link mode for permanent storage without checking your file retention setup. Temporary files may be cleaned up later.
Do not expect a built-in logo in the center of the QR code. Add branding in a later design step if needed.
Do not assume every protocol works.
