Frequently Asked Questions
Are my images uploaded to any server for compression?
No. The entire compression process takes place offline within your web browser. Your images never leave your local machine.
Does this compressor support PNG transparency?
Yes! However, compressing PNGs with transparency usually involves converting them to compressed WebP or keeping PNG format with localized resolution scaling. We support transparent exports.
What is the recommended quality value?
A quality level between 75% and 85% usually offers a 60-80% file size reduction with virtually no noticeable loss in visual quality.
