PNGs are sharp but heavy, which slows web pages down. Convert them to WebP to get a much smaller file that still keeps transparency. Just drop your PNG below.

Your image is converted in your browser and never uploaded.
Photos and detailed images saved as PNG often shrink dramatically as WebP. The new size is shown before you download.
WebP supports transparent backgrounds, including soft edges, so logos and cut-out product images stay see-through.
Smaller images mean pages load sooner, especially on phones, which is good for visitors and for search rankings.
Your PNG is converted by your own browser. It is never uploaded to a server, and nothing is kept after you close the tab.
No account, no email, no daily limit, and nothing stamped on your image. Convert as many PNG files as you like, one after another.
Converts PNG to WebP in any current browser on Windows, Mac, Linux, iPhone or Android. There is nothing to download or install.
PNG is lossless, which is ideal for editing, but it makes photos and large graphics heavy. On a website, those extra kilobytes add up to slower pages.
WebP was designed for exactly this. It's supported by every current browser, handles transparency, and is usually far smaller than PNG. This converter redraws your PNG at the same size and saves it as WebP at the quality you choose.
Drop your .png file onto the converter, choose it from your device, or paste a screenshot with Ctrl+V or Cmd+V.
WebP is already selected. Adjust the quality slider to balance size and detail.
Compare the new file size with the original, then download your WebP.
Converting is often only the first step. These tools work the same way, in your browser, and accept the file you just made.

.png
PNG was created in 1996 as an open replacement for GIF. It is lossless: every pixel is stored exactly, so saving a PNG again never wears the image down.
It supports full transparency, including soft, partly see-through edges, which makes it the usual choice for logos, icons, screenshots and cut-out product images. The trade-off is size: a photo saved as PNG is several times larger than the same photo as a JPG.
Google's image format for the web
.webp
WebP was released by Google in 2010 to make images on the web smaller. It has a lossy mode based on the VP8 video codec and a lossless mode, and both support transparency.
For a photo, a WebP is usually smaller than a JPG of similar quality, and every current browser displays it. Outside the browser support is patchier: some older editors, print services and upload forms still don't accept it.

Lighter images are the easiest way to speed up a page. Page-speed tools like Lighthouse often suggest serving images in formats such as WebP.
Unlike JPG, WebP doesn't force a background color, so the image still sits cleanly on any page design.
Smaller files cost less to host and serve, and use less mobile data for your visitors.
Chrome, Edge, Firefox and Safari all display WebP, and most CMS platforms accept it as an upload.
It depends on the image. Photos and detailed images saved as PNG often shrink by well over half as lossy WebP, while simple flat graphics shrink less. The converter shows both sizes, so you can see the exact difference for your file.
Yes. WebP supports transparency, so transparent backgrounds and soft, partly see-through edges are kept.
This converter saves lossy WebP, so some detail is traded for size. At the default 85% quality the difference is very hard to see. For crisp screenshots or text, raise the slider to around 90% or more.
For photos and large images, usually yes: WebP loads faster and every current browser supports it. For images you'll keep editing, or that must be pixel-perfect, keep a PNG as your master copy.
No. The conversion runs entirely in your browser: your PNG is opened, turned into a WebP and saved on your own device. Nothing is sent anywhere, and nothing is kept once you close the tab.
Each one opens the same converter with its format already chosen, plus a guide to both formats.
