Frequently Asked Questions

How much can this shrink my image?

It varies by image content, but photos typically compress 40-80% smaller at moderate quality settings with minimal visible difference.

Will lowering the quality slider make the image blurry?

At very low settings you may see visible compression artifacts (blockiness); the live size estimate and preview let you find the sweet spot before downloading.

Does compression change the image dimensions?

No - this tool only reduces file size through compression; use the Image Resizer tool if you also need to change width/height.
