Frequently asked questions
Can PNG files always be compressed a lot?
No. PNG is usually lossless, and some PNG files are already optimized. Converting to WebP can often reduce the file more, especially for web use.
Will transparency be preserved?
Transparency is preserved when exporting as PNG or WebP. If you export to JPG, transparent areas are flattened onto a white background.
Are PNG images uploaded?
No. Your images are processed locally in your browser. They are not uploaded to a server.
