Transformez vos fichiers PNG en WEBP instantanément.

Réponse rapide

To convert PNG to WEBP, upload your PNG file to ezimagetools.com and press Convert — the WEBP comes back in a few seconds. A photograph saved as PNG is often several times larger than it needs to be, because PNG stores every pixel exactly whether or not anyone could tell. Some, yes. It is free, needs no account, and your upload is deleted within an hour.

About PNG

PNG stores every pixel exactly as it was and is the common format that supports transparency. That makes it the right choice for screenshots, logos and flat graphics, and a wasteful one for photographs.

Why WEBP instead

Converting to WEBP is how you make a page lighter without making it look worse: the same picture, roughly a third fewer bytes, and no browser released in the last five years will struggle with it.

Why convert PNG to WEBP?

A photograph saved as PNG is often several times larger than it needs to be, because PNG stores every pixel exactly whether or not anyone could tell. Converting that photo usually cuts the size by 80% or more with no visible difference. Converting to WEBP is how you make a page lighter without making it look worse: the same picture, roughly a third fewer bytes, and no browser released in the last five years will struggle with it.

Will I lose quality converting PNG to WEBP?

Some, yes. PNG stores every pixel exactly and WEBP does not, so the encoder discards the detail it judges least visible. On a photograph the difference is not something you can see at normal size, but it is a one-way trip — keep the PNG if you might need to edit the picture again.

Does transparency survive converting PNG to WEBP?

Yes. Both formats can store transparent pixels, so a cut-out or a logo with a clear background comes back exactly as it went in.

What is a PNG file?

Does converting change the size or dimensions of the picture?

The width and height in pixels stay exactly the same — only the way those pixels are stored changes, which is what changes the file size. Expect the WEBP to be smaller than the PNG in most cases. Use the Resize tool if you want to change the dimensions too.

Yes. Your file is processed on our server and deleted automatically within one hour. We never look at it, never share it, and never use it to train anything. There is no account to create.
