Frequently Asked Questions
Does PNG compression keep transparency?
Yes! Our compression preserves the alpha channel (transparency) of your PNG images.
How is PNG compression different from JPG?
PNG uses lossless compression by default, meaning no quality is lost. However, you can choose a quality level to convert to lossy compression for even smaller files.
Can I compress PNG screenshots?
Absolutely! Screenshots often compress very well, with typical reductions of 60-80%.
Are my PNG files safe?
Yes. Everything runs in your browser — no files are uploaded to any server.
