How to convert PNG to WebP
- Click the upload box above, or drag your PNG image onto it.
- Press the Convert to WebP button.
- Check the preview, then click Download WEBP to save the file.
The conversion happens inside your browser, so there is nothing to install and no account to create. If the tool says your browser cannot create WebP files, try the same steps in Chrome, Edge, or Firefox.
Why convert PNG to WebP?
PNG is a great format for logos, icons, and screenshots, but its files can get large, especially for detailed images. WebP can store the same kind of image in a much lighter file, and unlike JPG, it still supports transparent backgrounds. That combination is why many designers and site owners switch their PNG graphics to WebP.
Lighter images load faster, use less bandwidth, and take up less storage. If your website has a lot of PNG graphics, converting them is one of the quickest ways to improve loading speed without changing how the pages look.
When converting to WebP makes sense
- You want a smaller file but still need a transparent background.
- You are preparing images for a website and care about page speed.
- You have many large PNG screenshots or graphics taking up space.
Things to keep in mind
This tool saves WebP at high quality, which is a lossy setting, so it is not a pixel-for-pixel copy of the original PNG. For everyday use the difference is very hard to see, but keep your original PNG if you may need to edit the image again. If you need a format that opens almost everywhere, use the PNG to JPG converter instead.
Frequently asked questions
Is this PNG to WebP converter free?
Yes. There is no cost, no signup, and no limit on how many images you convert.
Will my images be stored on your server?
No. The conversion runs in your own browser, so your image is not uploaded to my server and I never see it.
Does WebP keep the transparent background?
Yes. Unlike JPG, WebP supports transparency, so a transparent PNG stays transparent after conversion.
Will the WebP file be smaller than my PNG?
Usually, yes, and often by a lot. Results depend on the image, so compare both files before replacing the original.
Why does it say my browser cannot create WebP files?
Some browsers cannot save images as WebP. Chrome, Edge, and Firefox work well, so open this page in one of them and try again.
Can I convert multiple images at once?
Right now the tool converts one image at a time. Upload the next image after you have downloaded the first one.
