Compression Control

Smart Compression

"Smart" compression is a unique image compression technique. It optimizes the size of your presentation striving to provide the highest quality of image content.

Images can be stored in Flash format with "Lossy"(JPEG) or "Lossless"(PNG) compression. "Lossy" is the most convenient for photos and realistic images since this compression type allows decreasing the image size up to 10+ times with insignificant quality losses. In case you use diagrams, sketches, charts in presentation, it's better to apply "Lossless" compression which converts images with the highest quality. So the both types have their pros and cons.

Since presentations usually contain various types of images there is no best choice of the compression type - you either lose in the quality or the size. In this case "Smart" compression is what you need! The unique FlashSpring "Smart" compression technique analyses each image's content, automatically determines its type and chooses the best way of saving it in Flash format. This helps to keep the quality high and the size small!
