Frequently asked questions
Does this work on PNG files?
Yes — PNGs are re-encoded as compressed JPEGs (unless you need transparency, in which case output stays PNG at a reduced size).
Will I lose image quality?
Some, depending on the slider — that's the trade-off. Preview each result before downloading.
Can I compress many images at once?
Yes — add multiple files and download them together as a ZIP.
