Find Quick Answers

Does this tool preserve PNG transparency?

Yes, the tool fully preserves the alpha channel (transparency) when resizing PNG files.

Will my images be stored on your servers?

What happens if I don't maintain aspect ratio?

If you disable 'Maintain Aspect Ratio', the image will be stretched or squished to exactly match your width and height inputs.
