Frequently asked questions

What is a PNG file?

PNG is a lossless image format with transparency support, ideal for graphics, logos, and screenshots.

Why convert PNG to WebP?

PNG files can be large, especially for photos. WebP files are noticeably smaller, which speeds up websites and saves storage.

Will I lose image quality?

WebP compression is very efficient — at high quality the result looks virtually identical to the original while being smaller.

Are my images uploaded anywhere?

No. The whole conversion runs in your browser, so your PNG files never leave your device — safe for personal photos.
