Compress image size in kb or mb

Image compression works by optimizing the image data in two ways: 1) Lossless compression removes unnecessary metadata while preserving quality, and 2) Lossy compression slightly reduces image quality to achieve smaller file sizes. Our tool uses both methods intelligently to give you the best results.

JPEG is generally best for photographs and complex images, offering excellent compression ratios while maintaining good quality. PNG is better for images with text, sharp edges, or transparency. Our tool automatically suggests the best format based on your image content.

Compression ratios vary depending on the image content and original size. Typically, you can reduce file size by 30-80% while maintaining good visual quality. Photos with lots of details might compress less, while simpler images can compress more.

Our smart compression algorithms minimize quality loss while reducing file size. You can choose between different compression levels: high quality (minimal visible change), balanced (good compression with minimal quality loss), or maximum compression (smaller files with some quality reduction).
