Frequently Asked Questions

Is transparent background preserved when compressing PNG files?

No. The output is converted to JPEG format, so transparent areas are filled with a solid white background.

Does the output match the target size exactly?

The tool iteratively adjusts JPEG compression quality to approach the target, so minor deviations may occur depending on image complexity.
