About SJ Creation Tool Box

SJ Creation Tool Box is a free collection of 160+ online tools designed for developers, designers, students, and professionals who need to process files quickly and privately.

Our Mission

We believe that essential tools like PDF compression, image conversion, and document formatting should be free, private, and accessible to everyone. That is why every tool on our platform runs 100% in your browser — your files are never uploaded to any server.

What We Offer

  • 127 PDF Tools — Merge, split, compress, convert, protect, edit, watermark, and more
  • Image & Video Tools — Convert, compress, and transform media files
  • Developer Tools — JSON formatter, Base64, regex tester, QR generator, and more
  • Android Tools — Boot animation creator, APK analyzer, ADB commands

Privacy-First Design

Unlike most online tool websites, we made a deliberate architectural choice: zero server-side file processing. Every operation — from merging a 100-page PDF to converting spreadsheets to Excel format — happens entirely within your browser using JavaScript libraries like pdf-lib, pdf.js, and SheetJS.

This means:

  • Your files never leave your device
  • No file data is stored, cached, or logged
  • Works offline once the page loads
  • Completely safe for confidential and sensitive documents

Technology

Our tools are built with modern web technologies:

  • pdf-lib — PDF creation, editing, and manipulation
  • pdf.js (by Mozilla) — PDF rendering and text extraction
  • SheetJS — Real Excel spreadsheet generation
  • PptxGenJS — Real PowerPoint file creation
  • JSZip — ZIP, EPUB, and DOCX file assembly
  • HTML5 Canvas — Image processing and rendering
  • FFmpeg.wasm — Video processing in the browser

Who Built This?

SJ Creation Tool Box is developed and maintained by Shashan Soni, a web developer passionate about creating useful, privacy-respecting tools. The project started in June 2026 and has grown to serve users worldwide.

Trust is earned through transparency. Here's why you can rely on SJ Creation Tool Box:

Advertising & AI Solutions

This website is free to use and supported by non-intrusive display advertising through Google AdSense. We do not use pop-ups, interstitials, or aggressive ad formats. Ads are clearly separated from tool content and do not interfere with functionality.

We are also planning to integrate AI-powered solutions into our platform. This includes intelligent document analysis, AI-assisted image enhancement, smart format detection, and context-aware tool recommendations. Our goal is to combine the privacy of local processing with the power of modern AI to deliver smarter, faster results — while keeping your data on your device whenever possible.
