FAQ
Frequently Asked Questions
What quality value should I use?
Try 0.75 for a balanced result. Lower values reduce size more but can introduce visible artifacts.
Will PNG images always become smaller?
Not always. Some PNGs are already optimized or are better converted to WebP/JPG depending on the content.
Are images uploaded for compression?
No. Compression runs in your browser.
