Whether you're optimizing graphics for a web project, shrinking photos for a social media upload, or compressing scanned documents for email, this tool offers fine-grained control. The real-time quality slider lets you see exactly how your image will look before you commit, allowing you to strike the perfect balance between high-resolution clarity and ultra-small file sizes.
