Notes
Important points are grouped with reasons so you can make decisions before using the tool.
Format
Image Compression does not convert formats. Use Image Format Conversion when you need a different output format.
Size
PNG and GIF files can grow after re-encoding. The default setting keeps the original file when the compressed result would be larger.
Privacy
Selected images are not sent to an external server.
