Generating QR Codes for Links
Every short link in StackBloom comes with a built-in QR code generator. Create print-ready QR codes with custom sizes, your brand logo, and high error correction — perfect for menus, flyers, packaging, and event signage.
Step 1: Open any short link in your dashboard
From the URL Shortener dashboard, click on any short link to open its detail page. The QR code button is always visible in the top action bar alongside the copy and edit buttons, so you can generate a code for any link in just two clicks.
- QR codes always point to your short link URL, not the destination URL directly
- This means if you update the destination URL later, the printed QR code still works
- Analytics track QR code scans the same way as regular link clicks
- Use the referrer data to distinguish QR scans from other traffic sources
Step 2: Click the QR Code button
Click the QR Code button to open the QR code editor panel. A preview of the generated code is shown immediately on the right. All changes you make in the editor update the preview in real time.
- The default QR code is generated instantly with standard settings
- No additional configuration is needed for basic use — just download and go
- The editor panel stays open until you close it, so you can try multiple configurations
Step 3: Choose QR code size and error correction level
Set the Size in pixels for digital use or points for print. For the Error Correction Level, choose from Low (7%), Medium (15%), Quartile (25%), or High (30%). Higher correction means the QR code can still be scanned even when partially obscured or damaged.
- Low (L): smallest file size, use only for perfect conditions
- Medium (M): good balance for digital screens and clean prints
- Quartile (Q): recommended for packaging and outdoor signage
- High (H): required when adding a logo to the center of the QR code
- For print use, export at least 1000px or use the SVG format for infinite scaling
Step 4: Add your logo to the center (optional)
Toggle Add Logo and upload your brand logo image. The logo is placed in the center of the QR code at a size that covers roughly 20–30% of the total area. A white padding is added automatically around the logo for better contrast.
- Use a square or circular logo for the best visual result
- PNG with transparent background is recommended for the cleanest look
- Always use High (H) error correction when adding a logo
- Test the final QR code on multiple devices before printing at scale
Step 5: Download as PNG or SVG
Click Download PNG for raster use (web, email, PowerPoint) or Download SVG for vector use (print, packaging, large-format signage). SVGs scale to any size without losing quality and are the best choice for anything that will be printed.
- PNG files are suitable for everything up to about A4 / Letter size print
- SVG files are infinitely scalable — perfect for banners and billboard-size prints
- Both formats include the logo if one was added
- Downloaded QR codes are yours to use commercially without attribution
💡 Tip: Use high error correction when adding a logo to the QR code center. Because the logo covers a portion of the QR code's data modules, the High (H) correction level ensures enough redundancy exists for scanners to reliably decode the code even with the logo in place. Never use Low or Medium correction with a logo.
