Ever noticed how most “free” image/PDF compressors work?
👉 Upload your file
👉 Wait
👉 Download
Simple… but also kinda risky.
Where does your file actually go?
So I built my own.
A privacy-first image & PDF compressor that runs entirely in your browser.
No uploads
No servers
No tracking
Your files never leave your device. Period.
Why I did this
Because I got tired of sending potentially sensitive files to random servers just to shrink a few KB.
And honestly… we can do better as devs.
