About the PNG to WebP Converter

Upload one or more PNG images and get smaller WebP files back instantly, with transparency still intact — WebP supports an alpha channel just like PNG, but usually produces a noticeably smaller file, which is why it's the common choice for logos and icons on fast-loading web pages.

WebP keeps transparency, unlike JPG, so it can replace PNG for logos, icons and interface graphics — usually at a smaller size. Transparent pixels stay transparent, and the quality setting lets you trade a little detail for an even smaller file.

A transparent logo

A 48 KB PNG logo with a transparent background converts to a 31 KB WebP at quality 90 — and the transparency is kept, since WebP has an alpha channel.

A screenshot

A 1440×900 screenshot.png of 105 KB becomes a 34 KB screenshot.webp at quality 80 — about a third of the size.

03

A photo saved as PNG

A 1600×1200 photo saved as a 3.11 MB PNG converts to a 332 KB WebP at quality 80 — around 90% smaller.

FAQ

Frequently asked questions

Quick answers to common questions about the PNG to WebP Converter.

How do I convert PNG to WebP?

Upload your PNG image(s) above — the format is already preset to PNG to WebP — then click Convert. Each file converts entirely in your browser.

Is this PNG to WebP converter free?

Yes. It's free, with no sign-up and no limit on how many images you convert.

Does converting PNG to WebP keep transparency?

Yes — WebP supports an alpha channel just like PNG, so transparent areas in your PNG stay transparent in the converted WebP file.

Why convert PNG to WebP instead of keeping PNG?

WebP is a modern format that's usually smaller than PNG at a similar quality, which speeds up page loads — a common reason web performance tools recommend it for logos, icons and graphics.

Are my images uploaded to a server?

No. Every conversion happens directly in your browser using the browser's own image encoder — your files never leave your device.

Can I convert WebP back to PNG?

Yes — use the dedicated WebP to PNG converter page, or just swap the format dropdowns here.

Does WebP keep text and thin lines sharp?

At high quality settings, yes. If text or fine lines look soft, raise the quality towards 100 and compare — flat graphics often stay small even at high quality.

Is WebP supported everywhere I need it?

Every current major browser — Chrome, Edge, Firefox and Safari — displays WebP, so it's fine for websites. Some older image editors and email clients can't open it, so keep the PNG if you'll share the file outside the web.

Is any metadata kept in the WebP?

No. Embedded extras such as comments or EXIF data aren't copied, because the image is redrawn and saved fresh. The pixels and transparency are what carry over.
