FAQ
Frequently asked questions
How does image compression work?
Drefly re-encodes the image at a lower quality and, if needed, a smaller resolution, choosing PNG or JPEG output automatically based on whether the image needs transparency.
Which compression level should I use?
Original keeps full source quality and only re-encodes if that shrinks the file, Low keeps very high quality with modest savings, Medium balances size and quality, and High gives the smallest file for casual use.
Will compression affect image quality?
Original is designed to avoid visible loss. Low, Medium, and High trade some visual quality for a smaller file, with High reducing quality the most. Medium is a good default for web use.
Is compressing an image free?
Yes, compressing an image is completely free with no signup and no limit on how many images you compress.
