What to know before converting PNG to WebP
- Transparency is kept: Transparent and semi-transparent pixels stay transparent in the WebP file.
- Our WebP output is lossy: The tool writes WebP with a quality setting. That usually saves space, but it is not a pixel-perfect copy of the PNG.
- Smaller in many cases, not guaranteed: Photos and colourful graphics often shrink a lot. Very simple graphics that PNG already stores efficiently may not get smaller.
Frequently asked questions
Does WebP keep the transparent background?
Yes. Transparent areas of your PNG remain transparent in the WebP file.
Is the WebP an exact copy of my PNG?
Not exactly. Our WebP output uses lossy compression, so tiny details can change. If you need a pixel-perfect copy, keep the PNG.
Will the WebP always be smaller?
No. It often is, particularly for photos, but some simple graphics are already very compact as PNG. The result panel shows both sizes.
