The compression will run entirely in your local browser memory using Web Workers without loss of transparent canvas data.

Tell the tool exactly how many KB you need (like 50KB or 100KB), and it will automatically compress the PNG to fit.

Your transparent signatures and logos are processed in your browser. They are NEVER uploaded to our servers.

Most compressors turn PNG backgrounds black or white. Our tool correctly preserves your invisible background.

Using advanced HTML5 Web Workers, your computer does the math instantly without waiting in a server queue.

Compress as many PNGs as you want, as often as you want. There are no hidden fees, limits, or subscriptions.
