Upload a PNG here and download it re-encoded as WebP; transparency is preserved and the file usually comes out smaller.

How to convert PNG to WebP

Choose a PNG file - it loads into a preview on this page, nothing is sent anywhere.
The output format is already set to WebP; adjust the quality slider if the tool offers one for your browser.
Click Convert, then use the download link to save the WebP file to your device.

PNG to WebP Converter

Last reviewed: 2026-07-06

Turn a PNG into a WebP right in the browser, in a single step.

The file picker sits above a small set of option fields that control how each PNG is re-encoded as WebP; the defaults suit typical web-delivery use, so a straightforward conversion needs no adjustment.

Key features

Opens your PNG locally in the browser - the file is never uploaded to a server.
Redraws the image on an HTML5 canvas and re-encodes it as WebP.
Lets you nudge the output quality to balance a leaner WebP against how faithfully it tracks the original PNG.
Exports the result as a downloadable blob, with no server round-trip.
Builds the download link for the output entirely client-side.

When to use it

Typical use: your target platform takes WebP but not PNG. Because WebP supports both lossy and lossless modes plus an alpha channel, a PNG's transparency carries straight through, and the re-encoded file usually lands noticeably smaller than the source PNG for the same picture - the exact reduction depends on the image.

PNG vs WebP

Property	PNG	WebP
Compression modes	Lossless	Lossy and lossless
Transparency (alpha channel)	Yes	Yes
Typical file size for the same picture	Larger	Usually smaller

Supported inputs

This picker takes PNG, JPG, WebP, AVIF, BMP, and GIF source files. If the photo is actually an iPhone .heic file rather than one of those, use HEIC to JPG instead - it converts straight to JPG, PNG, WebP, or a combined PDF.

For other image formats, browse the image conversion tools hub.

Privacy

Every step - reading the PNG, redrawing it, and writing the WebP - happens inside this tab through the Canvas API, so the PNG stays on your device and is never uploaded. What you convert is dropped when the page session ends and is never handed to an analytics or tracking service, and no account or signup is involved.
