Papa’s Best Optimizer

Shrinks images and documents losslessly by optimizing existing compression. Run it comfortably in the background to save hard disk space and bandwidth.

Compression is a tradeoff between computing time and file size. Smartphone cameras, for example, invest very little time in compression to avoid annoying pauses before the next photo can be taken. Papa’s Best Optimizer, on the other hand, takes these files and computes until it finds the most compact form. This works with JPG photos and PNG graphics, but also with spreadsheeds, presentations, and much more.
