Web I Like to Use | All in One Utility Tools

Stop trading privacy for convenience, process all your sensitive files locally without ever uploading them to a server.

Daily tasks, like resizing ID photos, merging bank statements, or analyzing private CSVs often force users into a "privacy for convenience" trap. Most online tools require you to upload your files to their servers, where they can be stored, tracked, or leaked. Existing offline solutions are often clunky and require heavy installations.

I built Wiluse as a 100% client-side "Swiss Army Knife." My approach was to shift the processing power from the server to the browser's own memory. By leveraging modern Web APIs and WASM-based libraries, Wiluse ensures that zero bytes of user data ever leave the local machine. It’s a "zero-trust" utility suite that feels as fast as a desktop app but runs in a tab.

*This project was built using vibe coding through Google Antigravity.

Features

• Privacy-First Architecture: 100% local processing; no server uploads, ever.
• 50+ Specialized Tools: Deep categories across Image, PDF, Developer, Generator, and Workspace categories.
• Secure Data Testing: High-performance spreadsheet analysis using exceljs (migrated specifically to avoid industry-standard vulnerabilities).
• Dev Productivity Suite: From JWT decoders and Responsive Previews to custom JSON-to-Class generators.
• Architecture & Technical Highlights
• I utilized Next.js 16 with Turbopack for the foundation to ensure lightning-fast navigation. I chose specific libraries like pdf-lib and exceljs because they provide low-level control of file headers without requiring a Node.js backend. For heavy tasks like OCR, I integrated Tesseract.js to run optical character recognition directly via Web Workers.
