Technical FAQs

Does converting JPG to PNG make it higher quality?

No, you cannot regain quality lost in a JPG. However, it prevents *further* quality loss if you plan on saving the file multiple times.

Can I add transparency now?

Yes! Once it's a PNG, you can use any image editor to remove the background, a feature not supported by the JPG format.
