PNG to WebP Converter — Free & Online

PNG is lossless and keeps transparency, but it produces noticeably larger files than modern formats for the same image. WebP keeps the transparency support while typically shrinking the file substantially — a straightforward win for website images, app assets, or anywhere file size matters. This tool converts entirely on your device: drop in one PNG or a whole batch, adjust the quality slider if you want an even smaller file, and download each converted image with a live before/after preview.

Frequently asked questions

Why convert PNG to WebP?
WebP typically produces meaningfully smaller files than PNG at the same visual quality, which means faster-loading web pages and less storage used — without giving up PNG’s support for transparency.
Does WebP support transparency like PNG?
Yes — WebP fully supports alpha transparency, so transparent PNGs convert without losing that.
Will image quality change?
The quality slider defaults to 90 — near-lossless — since the point of this tool is a smaller file in the same format family, not aggressive compression. Lower it if you want an even smaller file.
Is WebP supported everywhere?
All modern browsers support WebP. A handful of older tools or platforms may not — check where you plan to use the file if you’re unsure.
Are my images uploaded anywhere?
No. Conversion happens entirely on your device in a background thread; files never leave your browser.
