1. Why I Built It
As a developer, I often needed to resize images.
Sometimes it was for profile pictures, sometimes for blog thumbnails, passport photos, product images, or social media posts.
Every time I searched online, I found the same problems:
- Watermarks on downloads
- Daily usage limits
- Slow processing
I thought:
"Why not build a simple image resizer that anyone can use for free?"
That idea eventually became part of QuickGenerator, an online toolkit that includes image tools, PDF tools, and document converters.

2. Tech Stack
The project is built using:
- ⚛ React 19
- ⚡ Vite
- 🔥 Firebase Authentication
- ☁ Firebase Hosting
- 🎨 Tailwind CSS
- 📝 TypeScript
The goal was to keep everything lightweight and responsive.
3. Features
The Image Resizer currently supports:
- Upload JPG, PNG and WebP images
- Resize using custom width and height
- Maintain excellent image quality
- Fast browser-based processing
- Responsive UI
- Works on desktop and mobile
4. What I Learned
This project taught me that users don't always need more features.
Often they simply want software that is:
- Fast
- Reliable
- Easy to understand
Keeping the interface simple ended up being one of the best decisions.
5. Part of a Bigger Project
The Image Resizer is only one tool inside QuickGenerator.
The platform also includes:
- PDF Merge
- PDF Split
- PDF Compressor
- Image Compressor
- Background Remover
- JPG to PDF
- PDF to JPG
- Word to PDF
- PDF to Word
- PowerPoint to PDF
- PDF to PowerPoint
- QR Code Generator
- Password Generator
The idea is to provide one place for common productivity tasks instead of making users visit multiple websites.
An image resizer may seem like a simple tool, but thousands of people need one every day for work, school, business, and personal projects.
