miniPNG will reduce the size of your PNGs
Your files are uploading:

miniPNG is free and fast PNG optimizer. It uses the same algorithm used by TinyPNG and Kraken.io, but while those two have very strict limits for their free users (like, for example, Kraken only lets you upload <1mb files, and TinyPNG won't accept more than 20 files at once and none of them can weigh more than 5mb), miniPNG has no such limits. With us you can compress unlimited amount of PNG files weighting up to 30mb each.
You're welcome!
