How do I convert a PNG to WebP with this tool?

Drag and drop your PNG onto the converter (or click to browse), then click Export — WebP is already pre-selected as the output format. Pick a quality level or set a target size in KB, then download the WebP file with its transparency intact. It is completely free and runs entirely in your browser via the Canvas API, so your PNG is never uploaded.

Does PNG to WebP keep transparency?

Yes. WebP supports a full alpha channel, so transparent areas of the PNG remain transparent in the exported WebP.

How much smaller is WebP than PNG?

WebP lossless is about 26% smaller than PNG on average, and quality-controlled WebP (what this tool exports) is usually far smaller still — often a fraction of the PNG size.

What quality setting should I use?

For screenshots and UI graphics, 90+ keeps edges crisp. For photos, 80–90 is usually visually indistinguishable. You can also set a target size in KB.

Are images uploaded to a server?

No. The conversion runs entirely in your browser using the Canvas API; your images never leave your device.

Is converting PNG to WebP free?

Yes — converting PNG images to the smaller WebP format (with transparency preserved) is completely free, forever. No account, no sign-up, and no limit on how many files you convert. The Canvas API handles the entire conversion in your browser; your images are never sent to any server. The site is ad-supported.

Does it work offline?

Yes. After the page loads, the conversion needs no server connection.

What formats are supported?

Input: JPEG, PNG, WebP, and AVIF (any of these can be loaded). Output: JPEG, PNG, or WebP — AVIF output is not supported by browsers.

Is there a file size limit?

No artificial limit. The practical limit is your device’s available memory (typically tens of MB or more). Very large images may take longer to convert.
