Frequently asked questions
Will compressing reduce image quality?
Some quality is traded for a smaller file size — use the slider to find the balance that works for your use case. Lower quality settings produce smaller files.
Can I compress multiple images at once?
Yes — add as many images as you like and they'll all be compressed in one pass, downloaded together as a ZIP.
What image formats are supported?
JPG and PNG are supported. PNGs are re-encoded losslessly where possible; JPGs are re-encoded at your chosen quality.
