How PNG compression works
PNG is lossless, so the big savings come from reducing the number of colours to a smart palette — almost invisible for screenshots, logos and illustrations. For photographs, converting to JPG saves even more.
Frequently asked questions
Will my transparent background stay?
Yes — PNG output keeps the alpha channel.
Is my photo uploaded anywhere?
No. The image is resized inside your browser and never leaves your device — important for ID photos and signatures.
