Jun 5, 2012Matthew Prince

Summary
Introduced Polish, an automatic image optimization feature that reduces image file sizes by removing unnecessary bloat (lossless mode) and applying compression algorithms (lossy mode). Lossless mode offers an average file size reduction of 21%, while lossy mode achieves an average reduction of 48%. Polish is available for paid accounts and operates by optimizing images in the cache upon fetching from the origin.
