Customize Your QR Code

Brevr gives you full control over how your QR code looks — color presets for quick setup, custom color pickers for precise branding, six dot patterns for visual variety, and two download formats for digital or print use.

What You’ll Learn

  • How to use color presets and custom colors
  • Which dot pattern to choose
  • When to download PNG vs. SVG

Color Presets

Presets let you apply a coordinated foreground and background color pair in one click. Brevr includes six built-in presets:

PresetForegroundBackground

Custom Colors

Set any foreground and background color using the custom color pickers. Two rules to follow for reliable scanning:

  1. Keep contrast high — the foreground (dots) must be clearly distinguishable from the background. Low contrast causes scan failures on some devices.
  2. Dark foreground, light background — QR code scanners are optimized for this direction. Inverted (light on dark) works but may fail on older readers.

Dot Patterns

Brevr supports six dot patterns that change the shape of the QR code modules:

PatternDescription
SquareDefault rectangular modules — maximum compatibility
RoundedModules with rounded corners — softer, modern look
DotsFully circular modules — high visual contrast
Extra RoundedHeavily rounded, flowing shape
ClassyPointed inner corners — refined, structured appearance
Classy RoundedCombines classy and rounded for a balanced style

All patterns use error correction level H, which means up to 30% of the QR code can be obscured or damaged and it will still scan correctly. This makes branded and stylized codes just as reliable as plain black-and-white ones.

Download Formats

FormatResolutionBest For
PNG2048 × 2048 pxSocial media, email, web, presentations
SVGVector (infinite scale)Print, packaging, signage, business cards

Always use SVG for anything printed. PNG at 2048 px looks sharp on screen but degrades when scaled up for large-format print. SVG renders at the exact resolution of the output device — no blurring at any size.


Frequently Asked Questions

Does the dot pattern affect scannability?

No. All six patterns use error correction level H (the highest level), so the code is just as scannable as a standard square pattern. That said, always test the final code with multiple devices before committing to a large print run.

Can I change the style of an existing QR code?

No — visual style is set at creation time. To use a different preset, color, or pattern, create a new QR code pointing to the same short link, then replace the old one in your materials.

What contrast ratio is safe?

A contrast ratio of at least 4:1 between foreground and background is recommended for reliable scanning across all devices. Higher contrast is always better.
