Building a Privacy-Focused Image Compressor Tool with Next.js

Recently, I built a small web project called Image Compressor Tool — a simple online tool that allows users to compress images directly in their browser.

The idea behind the project was simple:

Compress images quickly without uploading them to a server.

Why I Built It
Image compression is something many people need — whether they are uploading images to a website, sharing them online, or simply trying to save storage space.

However, many existing tools involve uploading your images to a remote server before processing them.

For certain types of images, users may prefer not to upload their files anywhere.

So I wanted to build a tool where the compression happens directly inside the browser.

Key Features
The tool currently provides:

🖼️ Browser-based image compression
🔒 No image upload required
⚡ Fast and simple workflow
📦 Reduced image file size
📱 Responsive interface
💻 Works across desktop and mobile devices
How It Works
The basic workflow is intentionally simple:

Select Image → Compress → Download

Instead of sending the image to a backend server, the image is processed on the user’s device.

This means the application doesn’t need a dedicated image-processing backend for the basic compression workflow.

Focus on Performance
While building the project, I wanted to keep the application lightweight and fast.

Download the Medium app
I focused on things like:

Optimizing the user experience
Keeping the interface simple
Reducing unnecessary network requests
Using static generation where possible
Making the application responsive
Improving SEO fundamentals
The goal wasn’t to build a complicated application.

The goal was to build one useful tool and make the experience as simple as possible.

What I Learned
This project also gave me an opportunity to explore areas beyond just building the UI.

I worked more with:

Next.js
React
TypeScript
SEO-focused web applications
Static generation
Web performance
Client-side image processing
Responsive UI development
One thing I particularly enjoyed was thinking about the product from a user’s perspective rather than only from a developer’s perspective.

A small tool can still have a lot of interesting engineering and product decisions behind it.

What’s Next?
This is just the beginning.

I plan to continue improving the tool based on real user feedback and potentially add more useful image-related features in the future.

If you work with images frequently, give it a try and let me know what you think.

If you have any suggestions for improvements or features you’d like to see, I’d love to hear them. ❤️
