Hey devs ?
If you've ever needed to compress or convert images before uploading them — whether to speed up website load time, reduce storage, or improve performance — you’re not alone.
That’s why I built a fully functional image compressor and format converter app using Next.js, Tailwind CSS, and EmailJS.
Today, I’m sharing how it works, how you can use it or learn from it, and where to get the full source code to build your own version or start selling as a tool.
Live Demo

? What the App Does
This is not just a demo — it's a real app with production-ready features. Here's what you can do:
Compress images (JPG, PNG, WebP)
Convert between formats (e.g., PNG → JPG, JPG → WebP, etc.)
Drag & drop or select files
Preview before download
Download converted & compressed output
Get user queries via EmailJS contact form
It’s a clean and fast UI with modern styling — responsive and mobile-friendly.
?️ Tech Stack Used
Frontend: Next.js 15
Styling: Tailwind CSS
Email Handling: EmailJS (for feedback/contact form)
? Why It's Useful for Developers
Whether you're a dev looking to build tools or just want to practice real-world projects, this app will help you understand:
Image compression workflows in the browser
File handling and preview generation in React/Next.js
Optimizing UX for drag & drop + download flows
Using third-party APIs (EmailJS) in a production-safe way
? Get the Full Source Code
You can download the complete project with comments and clean structure from here:

Feel free to reply with questions, ideas, or feature suggestions. If you build something based on this, tag me — I’d love to see it!
Let’s keep building useful things together ?
