Maker
📌
👋 Hi Product Hunt! I'm Bansidhar, the founder of 99Tools.
I built this Image Compressor because I was frustrated with online tools that:
Limit file sizes
Require uploads to their servers
Ask you to create an account
Add watermarks or daily limits
So I created a tool that keeps things simple.
What makes it different?
✅ 100% Private – Images are processed entirely in your browser. Nothing is uploaded.
✅ Batch Compression – Compress multiple JPG, PNG, and WebP images at once.
✅ Adjustable Quality – Balance image quality and file size with an easy-to-use slider.
✅ Completely Free – No registration, subscriptions, or hidden restrictions.
✅ Works Everywhere – Windows, macOS, Linux, Android, and iPhone.
This tool is especially useful for:
Developers optimizing website performance
Bloggers improving Core Web Vitals
Designers sharing lightweight assets
SEO professionals reducing page load times
Anyone who wants smaller images without sacrificing quality
I'd genuinely love your feedback:
What feature would make this tool even better?
Are there any image workflows you'd like to simplify?
Thanks for checking it out and supporting an independent maker! 🚀

Really useful for quick batch compression without the privacy headache of uploading. One thing that would make it even better is letting users set a target file size in KB rather than only a quality slider, so you can hit specific page speed goals without guessing compression levels.

honestly the local browser processing is what sold me, dragged in a folder of photos and it spat out compressed versions without anything leaving my machine. pretty handy for quick web optimization

Love that it runs locally, no uploads is huge for privacy. One feature I'd really appreciate: a drag-and-drop folder support so I can compress entire directories at once instead of selecting files individually. Would save so much time on big projects.

Really appreciate that it runs entirely in the browser without uploading anything, that kind of privacy-first approach for image compression is rare and shows thoughtful execution.
