DocTools: PDF & Photo Tools

A while ago, I needed to merge a few PDFs and compress document photos. Like most people, I searched online and found plenty of web tools. But as I was about to drag and drop my personal documents, a thought hit me: Why am I uploading sensitive personal files, passports, and IDs to random third-party servers just for simple compression?

That privacy concern inspired me to build DocTools: PDF & Photo Tools, which I launched on Android in late 2025.

💡 What is DocTools?

It’s a fast, lightweight, and completely offline utility suite for Android designed to handle daily document tasks with zero server uploads:

• 📄 Photo to PDF Converter (Convert JPG, PNG, WebP)

• 📉 PDF & Image Compressor (Reduce size to target KB/MB limits offline)

• 🧩 Merge & Split PDF (Combine or extract pages easily)

• 🔒 Lock & Unlock PDF (Password protect files locally)

• 📷 Offline Document Scanner & Watermark tool

• 🛡️ 100% Privacy-First: No sign-up, no tracking, and no internet required. Everything stays on your phone.

🚀 Current Stage & Next Steps

Since releasing version 1.0, I've been constantly updating the app (currently at v2.5.0) to improve compression speed and UI experience based on user feedback.

💬 Would love your feedback!

If you handle sensitive documents on mobile and care about privacy, I’d love for you to try DocTools on Google Play and let me know:

1. What features do you use most often in document utility apps?

2. Any UI/UX improvements or new features you’d like to see?

Thanks for reading, and happy hacking! 🙌
