The Bottom Line
TinyPNG is a fantastic compression tool with a best-in-class plugin ecosystem. But if you need more than just PNG/JPEG/WebP compression — format conversion, larger files, camera RAW support, or API access without monthly limits — KoalaPic is the more complete solution. TinyPNG is the go-to for WordPress and Shopify users who want one-click optimization. KoalaPic is the go-to for everyone else who needs a full image conversion toolkit.

Its simplicity and effectiveness have earned it a massive following and a rich ecosystem of plugins for WordPress, Shopify, Photoshop, and more.

KoalaPic's API is free where TinyPNG charges after 500 compressions per month.
