- Worth noticing
- For exact-size requests, it searches quality settings and checks that the next step would exceed the target.
Field notes
The page distinguishes ordinary lossy compression from lossless optimization: it says the latter can strip EXIF, GPS, and ICC metadata and rebuild Huffman tables while leaving decoded pixels identical. Its target-size workflow searches quality settings and, if none can meet the limit, says it will shrink the image instead. The site also says it returns the original when re-encoding would make the file larger.
