QrNestGen

The Brief

Build a fast, privacy-first QR generator that produces professional, on-brand codes entirely in the browser, with nothing sent to a server.

The Challenge

Most online QR generators track user data and output generic black-and-white squares that look cheap next to a polished brand. Users had to trade away either their privacy or their design quality.

For designers and marketers, that meant either risking data leakage through third-party tools or settling for codes that undercut the brand they were promoting.

Our Approach

We built a fully client-side generator that runs entirely on the user's device, so no data ever leaves the browser, and paired it with rich customisation for logos, colours, and patterns.

Everything from generation to export happens locally, which makes the tool both private by design and instant, with no server round-trips.

• 100% client-side processing, with no data transmission or tracking
• Custom logos, colours, and dot and eye pattern styles
• Print-ready SVG and high-resolution PNG export
• Support for URLs, vCard, Wi-Fi, email, maps, and social links
• No account or subscription required

Scope of Work

• ▸Browser-based QR and barcode generator
• ▸Client-side rendering with no backend data flow
• ▸Brand customisation (logo, colour, patterns)
• ▸SVG and PNG export pipeline
• ▸Multiple QR content types (URL, vCard, Wi-Fi, and more)

The Outcome

QrNestGen gives users a professional QR tool that respects their privacy completely, producing branded, print-ready codes without ever sending data to a server.

Designers and marketers get scalable, on-brand output in seconds, with none of the tracking or quality compromises of typical online generators.
