JPEG Optimizer & Quality Adjuster
Find the perfect balance between image quality and file size. Adjust the JPEG compression ratio in real-time to drastically reduce the weight of your photos.
Optimize High-Resolution Photos
JPEGs (or JPGs) are the standard format for photographs, but high-resolution camera shots can exceed 10MB, which is disastrous for web performance. The JPEG algorithm allows you to adjust the 'Quality' scale (from 1 to 100). This tool lets you visually adjust that scale in real-time. Dropping a photo from 100% to 80% quality is usually indistinguishable to the human eye, but it reduces the file size by 60%.
Why Use Our JPEG Optimizer?
- Real-Time Preview: See exactly when compression artifacts appear.
- Massive Size Reduction: Easily shrink 10MB photos down to 200KB.

Frequently Asked Questions
JPEG compression works by grouping pixels into 8x8 blocks. At very low quality settings, these blocks become highly visible (known as compression artifacts).
Use JPEG for complex photographs with thousands of colors. Use PNG for logos, text, or images that require a transparent background.
