Frequently Asked Questions

Will my transparent background stay transparent?

Yes. WebP supports transparency, so see-through areas stay see-through.

Which quality should I use for logos and screenshots?

Use 90% or more for images with text or thin lines. Photos look fine at 80 to 85%.

Does it work in Safari?

Safari shows WebP images but cannot create them. Use Chrome, Edge or Firefox to make the WebP file.

When should I keep the PNG?

Keep PNG for files you will edit again or send to apps that do not open WebP, such as some office and printing software.
