FAQ
What quality setting should I use?
60-75 for web display looks identical yet halves file size; use 85-95 for archives; below 40 shows blocky artifacts.
Difference from the compressor tool?
This focuses on the single JPG quality parameter; the compressor combines resizing and more for maximum savings.
Is my image uploaded?
No, everything runs locally in your browser.
