About the Image Compressor
Adjust output quality and format to reduce image file size. Results depend on source image, dimensions and selected format.
How to use this tool
Choose an image, select an output format and quality, then click Process image, compare the original and result, and click Download. Compare the output visually before publishing.
Example
A quality value of 0.65 often creates a smaller lossy image than 0.95, but the result varies by image.
Tips for better results
Compression is not guaranteed to reduce every file; PNG can be larger than the source for some images.
Frequently asked questions
