I Built a Fully Private QR Code Generator with Logo Art, Scanner, Bulk Export, and PDF Support

Hey,

For the past few weeks I’ve been very deep in a redesign of the QR Code Generator on my site, Tool Desert.
Most QR code tools today follow the same pattern: basic version is free, but the good features requires payment, or they quietly collect your data on their servers. I wanted something different.

So I rebuilt it with one core principle: everything must run 100% in the browser — no servers, no tracking, no compromises on privacy.

Here’s what the new v3.7 version includes:

Major New Features!!!!

QR Code Art Mode :
This is the standout feature. You upload a logo and the generator turns parts of your logo into colored pixels inside the QR code. It creates beautiful, artistic QR codes while still being fully scannable.

Integrated QR Scanner :
You can scan QR codes directly on the website using your device camera or by uploading an image. Super convenient for quick testing.

Bulk QR Code Generation :
Support for generating many codes at once — either by pasting multiple lines or uploading a CSV file. Downloads everything neatly packaged in a ZIP.
Professional PDF Export :
Multiple layout templates (Minimal, Business Card style, Poster, QR-only), custom paper size/orientation, color controls, title/subtitle options, and toggle for watermark.
Improved logo handling, better error correction, rich styling options (dots, eyes, gradients), and multiple download formats (PNG, SVG, JPEG, WebP, PDF).

And also small feature but most other sites almost certanily keep it behind a pay wall which is branded QR codes which puts your logo in the middle of the QR code

The whole experience feels fast and clean because nothing ever leaves the user's device.

Why Privacy Matters to ME : (before you read it I do use Google analytics so PLEASE forgive me for that)

In 2026, people are becoming more conscious about where their data goes. I want Tool Desert to be a place where users can confidently use powerful tools without worrying about tracking or data leaks.

You can try the updated QR Code Generator here:

I’m currently maintaining 84+ free browser tools with the same no-signup, privacy-first philosophy.

Next on my list is a deep overhaul of the Password Generator.
I’d love to hear from the dev.to community:

Have you used any privacy-first tools that impressed you?
What features would make a QR code tool perfect for you?
Any feedback on the current implementation?
