Question 1

Why should I use WebP instead of JPG?

Accepted Answer

WebP is 25–35% smaller than JPG at equivalent quality. It's supported by all modern browsers and is Google's recommended format for web images.

Question 2

Does converting PNG to JPG remove transparency?

Accepted Answer

Yes. JPG doesn't support transparency, so transparent areas will be filled with white. Use PNG or WebP to preserve transparency.

Question 3

Does converting a GIF preserve the animation?

Accepted Answer

Converting GIF to PNG or JPG extracts only the first frame. To keep animation, convert to animated WebP.

Question 4

What is AVIF?

Accepted Answer

AVIF is a next-generation image format that offers even better compression than WebP. Browser support is growing but some older browsers may not support it.

Question 5

Can I adjust quality when converting?

Accepted Answer

Yes, a quality slider is available when converting to JPG or WebP. PNG is lossless so no quality setting is needed.
