Create QR codes and barcodes

A scancode is an image with its own editor. You set the content, pick a style and save the rendering into the gallery. The full configuration is embedded in the saved PNG, so reopening a scancode restores every setting.

Create a scancode

1. Click QR Code at the bottom of the left navigation, or choose Create Scancode from the capture button’s menu.
2. Pick a Code Type.
3. Enter the content, or pick a Payload Type and fill in its fields.
4. Style the code (QR only) and check the Scannability score.
5. Click Save to Gallery.

The code is saved as a PNG into the folder currently open in the gallery, and a Scancode saved message confirms it. If you save again while the editor is still open, the same file is updated. Undo and redo work for every setting, and typing in one field counts as a single undo step.

Code types

Code Type	Content
QR Code	Any text, or a structured payload (below)
Code 128	Alphanumeric data
EAN-13 (ISBN)	13 digits
UPC-A	12 digits
Code 39	A–Z, 0–9 and - . $ / + % and space
Data Matrix, PDF417, Aztec	Text or data

For the 1D barcodes (Code 128, EAN-13, UPC-A and Code 39), Show text under bars prints the encoded digits below the bars.

Size sets the pixel size of the saved image: 512, 1024 (default), 2048 or 4096 px. Larger sizes print more reliably.

QR payload types

Picking a Payload Type replaces the content box with dedicated fields:

Payload	Fields
Text, URL	Content
Email	To, Subject, Body (scanning opens a draft; nothing is sent)
Phone	Phone Number (include the country code)
SMS	Phone Number, Message
WiFi	Network Name (SSID), Password, security (WPA / WPA2, WEP, None (open))
vCard	First Name, Last Name, Email, Phone, Organization
OTP	Base32 Secret, Label, Issuer

Caution

A WiFi code stores the password as plain text, and an OTP code contains the secret that generates your sign-in codes. Anyone who scans the image can read them, so treat these images as credentials.

Error Correction controls how much of a QR code can be damaged or covered and still decode: L – 7%, M – 15% (default), Q – 25% or H – 30%. Higher levels make the code denser.

Style a QR code

Styling applies to QR codes only; other code types render plain.

• Style: Default, Rounded or Fancy. This sets the module and eye shapes in one step, and any change below overrides it.
• Foreground / Background: hex colors (default #000000 on #FFFFFF). Dark modules on a light background scan most reliably.
• Module Shape: 13 shapes, from Square (most reliable) through Rounded, Circle, the connected shapes, Diamond and Squircle, to decorative Leaf, Wave and Blob, and the sparse Dot and Dot grid.
• Eye Outer / Eye Inner: Square, Rounded or Circle for the three corner finder patterns.
• Art Theme: Neon Glow, Liquid Glass, Connected Squircle, Cut Corner Tech, Inset Rings, Stripe Eyes or Paint Splash. Intensity defaults to 50 (double-click to reset), and Variant is Conservative, Bold or Pastel.
• Logo: click Choose… to place an image in the centre. Scale sets its width as a fraction of the code (default 20%).

Note

Choosing an art theme or adding a logo forces error correction to H, so the modules they cover can still be recovered.

Scannability

The Scannability score (0–100) is a static check of contrast, quiet zone, module size and decorative geometry. It’s green from 80, amber from 60 and red below that, and any warnings are listed underneath. It grades your settings and doesn’t actually scan the code, so test anything important with a real phone.

If a code won’t scan, try these in order:

1. Increase contrast.
2. Lower the art theme’s Intensity.
3. Shrink the logo Scale.
4. Switch back to Square modules.

Use a saved scancode

• Reopen: open it from the gallery like any other item. The editor restores the content and every style setting.
• Find: search with the qr: or scancode: qualifier. The encoded content is also added as a tag. See Search.
• Drag out: drag the preview straight into another app to drop a PNG.
• Vector formats: the MCP export tool writes a scancode as PNG, SVG, PDF, JPEG, WebP or EPS. See the MCP overview.
