What we make
We publish a growing collection of free, browser-based tools that solve specific problems quickly and privately:
- Merge CSV — combine multiple CSV files vertically or horizontally, entirely in your browser.
- City Map Poster — generate minimalist, high-resolution map posters for any city worldwide.
- Thermal Label Converter — crop and print images or PDFs to fit 4×6 thermal label printers like Rollo, DYMO, and Zebra.
On the way
Native iOS apps, coming soon to the App Store
Several of our most-used tools are currently being rebuilt as native iOS apps for iPhone and iPad. These apps are in active development under C26 Labs LLC’s Apple Developer Program enrollment, with the same focus on speed, privacy, and clarity that powers our web apps.
How we build
Our web tools run client-side wherever technically possible. Your files, your data, and your content stay on your device — they are not uploaded to our servers, and we don’t track what you do inside the apps.
We don’t require accounts for our utilities. We don’t sell ads. We don’t resell data. We build the kind of internet software we want to use ourselves.
