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?
Low keeps the most quality with modest savings, Medium balances size and quality, and High gives the smallest file for casual use.
Will compression affect image quality?
Yes, higher compression levels trade some visual quality for a smaller file. 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.
Which compression level should I use?
Light compression keeps quality nearly identical, medium is a good balance, and strong gives the smallest file size for things like faster page loads.
