I Built 34 Developer Tools That Run Entirely in Your Browser — Including PDF & Image Processing

INTRO: "As developers, we paste sensitive data into random online tools
and upload confidential files to unknown servers every day without
thinking about where they end up. I built something to fix that."
THE PROBLEM: Talk about how you use PDF mergers, image compressors,
Base64 encoders, JSON formatters, and regex testers constantly, but
most online versions are ad-heavy, slow, nag you about file sizes,
or send your data to their servers.
THE SOLUTION: Introduce TextTools Pro. Explain that everything runs
client-side — no data ever leaves the browser. Even PDF merging and
image compression happen entirely in JavaScript.
LIST ALL 34 TOOLS: Organize by category:
- Text Tools (6 free)
- Encoding Tools (3 free)
- Generator Tools (4 free)
- PDF Tools (3 free) — highlight these, they're traffic magnets
- Image Tools (3 free) — highlight these too
- Developer Tools (15 premium)
THE PRICING STRATEGY: Explain why PDF and image tools are free
(they drive the most search traffic) and developer tools are premium
(developers are willing to pay for daily-use tools). Mention the
$29 lifetime deal alongside $4.99/mo.
TECHNICAL DETAILS: Mention pdf-lib for PDF processing, Canvas API
for image manipulation, all client-side JavaScript.
