How Jason’s ConvertCase Tool Turned an Hour’s Work into $20K/Month

Introduction

ConvertCase started with a simple need: Jason was tired of emails that felt like shouting. In an hour he wrote a script to convert ALL CAPS into readable text. He dropped it online at convertcase.net and didn’t touch any heavy marketing. Instead, he let Google index the tool and users discovered it organically.

How ConvertCase Works

Users visit the homepage, paste their text, choose uppercase, lowercase, or sentence case, then click “Convert Case.” Punctuation, spaces, and special characters stay put. Beyond text, the site now offers image format conversion (PNG, JPG, SVG), CSV-to-JSON and JSON-to-CSV data transforms, and random generators for text or numbers. All that grew from the first hour-long prototype.

Traction and Growth

At launch, traffic crept along. No paid ads—just SEO. Word spread. Conversions climbed as developers, marketers, and casual users found it useful. A “suggest a tool” box on the site lets visitors request new features. That simple feedback loop fuels every update. By watching search patterns and industry shifts, Jason plans additions that users really need.

Marketing & Monetization

ConvertCase pulls in about $20,000/month through on-site ads managed by Adapex. With minimal operating costs—around $20/month—the margins are huge. There’s also a “Buy Me a Coffee” page for small donations. The lean setup keeps overhead almost zero, while ad optimization keeps revenue climbing.

Unique Advantages

A tool that’s been live since 2006 has built trust. Users know it’s reliable and fast. The combination of multiple conversion utilities under one roof sets ConvertCase apart from single-function competitors. And the user-driven feature suggestions ensure the roadmap stays aligned with real needs.

Looking Ahead

Jason plans to expand the conversion suite, exploring file-to-file transforms, richer random data types, and potentially a paid tier for API access. With a decade-plus track record and zero real costs, ConvertCase is poised to keep growing.
