Frequently Asked Questions
Will PNG transparency be preserved?+
Yes. Our compression maintains the alpha channel, so transparency works perfectly.
How much smaller can PNGs get?+
Typically 30-70% reduction. Screenshots and simple graphics compress more than complex photographs.
Should I use PNG or JPG?+
PNG for transparency, logos, text, and screenshots. JPG for photographs and complex images.
Can I compress animated PNGs?+
Our tool handles standard PNGs. For animated PNGs (APNG), the animation may not be preserved.
Is WebP better than PNG?+
WebP offers better compression with transparency support. But PNG has wider compatibility across older browsers and apps.
