How do I convert PNG to WebP?+
Drop one or more PNG files into the tool above and WebP is already selected. Each image is converted at its original width and height with quality 90, and any transparency is kept. Move the Quality slider to make files smaller or sharper, and watch the size next to each file change. Download each WebP, or all of them as a ZIP.
Does PNG to WebP keep the transparent background?+
Yes. WebP supports transparency just like PNG, so transparent and semi-transparent areas stay as they were, including soft edges and shadows. That makes WebP a good replacement for PNG logos, icons and cut-out product photos on a website. If you need a JPG instead, pick it in the tool and choose the colour that fills the transparent areas.
Is WebP smaller than PNG?+
For photos and detailed images, usually by a lot, because PNG stores every pixel exactly. Flat graphics with few colours can come out close to the PNG, or occasionally bigger. The tool shows the size before and after for every file instead of promising a number, so you can keep the original PNG for any image where WebP doesn't help.
What WebP quality should I use for PNG images?+
Start at the default of 90, which looks the same as the PNG for almost every image. For photos on web pages, 75 to 85 gives noticeably smaller files. Screenshots, text and sharp line art show blur sooner, so keep those at 90 or higher. Change the slider after dropping your files and every image is converted again straight away.
Can I convert many PNG files to WebP at once?+
Yes. Drop up to 20 PNG files at once and each one becomes its own WebP with the quality you picked. Download them one by one, or all together as a ZIP. File names stay the same apart from the extension, so logo.png becomes logo.webp, and files with matching names get -2 added so nothing is overwritten.
What if a site won't accept my WebP file?+
Current web browsers all display WebP, but some older apps and upload forms still don't accept it. Keep your original PNG for those. If you only have the WebP, turn it back into a PNG with the WebP to PNG converter, which keeps the transparency. On your own website, WebP is the better choice for faster loading.
Are my PNG files uploaded anywhere?+
No. PNG to WebP runs entirely in your browser, so your images never leave your device and are never sent to a server. Reading, converting and zipping all happen locally on your computer or phone. You can check this yourself: open your browser's network tab while you convert, and you'll see that no image data is sent anywhere.
