After months of building, I just launched AAWebTools — a collection of free web tools that run entirely in your browser.
What I built
7 tools, zero signups required:
- 🎵 TikTok Video Downloader — no watermark, HD quality
- 🐦 Twitter/X Video Downloader
- 📄 Free Invoice Generator — 5 PDF templates, EN/FR support, international tax compliance
- 🤖 AI Content Detector — pure JS perplexity scoring, no API cost
- ✍️ AI Text Humanizer — Claude API backend
- 💰 Pay Stub Generator — supports USA, Canada, UK, France, Germany, Australia, Morocco
- 🖼️ Image Toolkit — compress, convert to WebP/AVIF, resize with social media presets — images never leave your browser
The tech stack
Pure HTML5 + Vanilla JS frontend (no React, no frameworks). Node.js backend only for the downloaders. Python container ready for future tools. Docker on a Hostinger VPS.
No frameworks = sub-1-second load time on all pages. Lighthouse 90+ across the board.
The privacy-first decision
The image toolkit was the most interesting challenge. Instead of sending files to a server (like TinyPNG does), everything runs client-side using the Canvas API and browser-image-compression library. Images never touch our server.
This was actually faster than server-side processing for most users because there's no upload/download round trip.
What's live now
All tools are live, free, and working. Would love feedback from the dev community — especially on the image toolkit and AI detector.
What free tools do you find yourself reaching for most often?
