01Context
People routinely upload private files to unknown servers just to convert or compress them.
02Problem
Server-side file tools cost money to run and ask users to trust a third party with their data.
03Objective
Offer a large catalogue of everyday file tools that run entirely in the browser.
04Work performed
- Built 600+ single-purpose tools that process files locally in the browser.
- Static hosting with no server compute.
- Search-focused page structure so each tool can be found directly.
05Engineering decisions
- Client-side processing: user files never leave the device, and hosting cost stays flat as traffic grows.
- Static site on GitHub Pages instead of an application server.
06Architecture
- Static pages per tool
- Browser APIs for file processing
- GitHub Pages hosting
07Results
4.3M+ requests and 213K+ visits in a 30-day window, per the published analytics post.
