When to use this conversion
Convert PNG to WebP when you want smaller web graphics without giving up transparency. WebP supports an alpha channel like PNG but compresses far better — ideal for logos, icons and UI assets on a website.
Technical details
WebP keeps PNG's transparency while often being several times smaller. It supports both lossless and lossy modes; for photographic PNGs the saving is largest. All modern browsers support WebP. Processing is server-side with immediate deletion.
Frequently asked questions
Does WebP keep transparency?
Yes — unlike JPG, WebP has an alpha channel, so transparent PNGs stay transparent.
How much smaller is it?
Often several times smaller than the PNG, especially for photographic or richly-coloured images.
Is it free?
Yes — no account, and the file is deleted right after conversion.
