What Does Image Quality Mean?
Quality controls can affect the balance between image appearance and file size. A lower quality setting generally produces a smaller file, while a higher setting generally preserves more visual detail.
Why Compress Images?
Compressing images can help reduce storage requirements and bandwidth usage. Smaller image files can also be useful when preparing images for websites, email attachments and online publishing.
