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.

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.

Nice clear scope—keeping the basic path entirely local is a meaningful privacy win, not just a performance choice. One thing I’d watch as usage grows is main-thread pressure on large batches: decoding and encoding in a worker (with transferable buffers or OffscreenCanvas where available), revoking object URLs, and showing a memory-aware fallback can keep the UI responsive on phones. It may also be worth stripping EXIF by default or making metadata preservation explicit, since location and camera fields can survive a client-side workflow even when pixels never leave the device.
Thanks for the great feedback!
Really solid suggestions. I'll definitely look into using Web Workers, OffscreenCanvas, and proper Object URL cleanup to keep the UI smooth during large batches. Stripping EXIF metadata by default also makes total sense for privacy—I'll work on adding these in an upcoming update!
