About this tool
Convert an image between PNG, JPEG and WebP with an adjustable quality for lossy formats, comparing before and after sizes, all in your browser.
Frequently asked questions
Does the quality slider affect PNG?
No. PNG is lossless, so the quality control only applies to the lossy JPEG and WebP formats.
Why does my JPEG have a white background?
JPEG cannot store transparency, so transparent areas are filled with white before the image is encoded.
