Questions
Which format is best for websites?
WebP is usually smallest for the same quality. Use PNG for images that need transparency and JPG for photos where WebP isn’t supported.
What happens to transparency when converting to JPG?
JPG has no transparency, so transparent areas become white.
Do you store what I enter?
No. Your input is processed to give you the result and isn’t saved.
Is this tool free?
Yes. It’s free to use with no sign-up and no limits for normal use.
