PNG to WebP converter: smaller images, the same pixels, nothing uploaded
Turn a PNG into a WebP in your browser. Keep every pixel with lossless WebP, or pick a quality for an even smaller file. See both sizes before you download.
or drop it here. JPEG, PNG or WebP.
Your image stays in this browser. Nothing is uploaded.
Why turn a PNG into WebP
WebP is an image format Google made for the web. A lossless WebP keeps exactly the same pixels as the PNG, see-through areas included, in a smaller file. Google says lossless WebP files are about a quarter smaller than the same images as PNG.
Smaller images load faster on a website and take less room in email and chats. All current browsers can show WebP.
Lossless or lossy
Lossless is the safe choice for screenshots, logos, drawings and anything with text: only the file size changes. Lossy drops detail the eye barely notices and makes photos much smaller. Start at 80–90% and compare the two pictures before you download.
Private by design
The image is converted on your device and never uploaded, even in Safari, where the tool brings its own WebP encoder. The new copy has no location, date or camera details.
Frequently asked questions
Does converting PNG to WebP lose quality?
Not with Lossless, which is the starting choice for PNG images: every pixel stays the same. Lossy makes a smaller file by dropping fine detail, so check the preview first.
Does WebP keep transparency?
Yes. Lossless and lossy WebP both keep see-through areas, so logos and cut-out images stay transparent.
Why is my WebP bigger than the PNG?
It can happen with very small images, or ones PNG already stores well, such as large areas of flat colour. Try Lossy at a high quality, or keep the PNG.
Can I use WebP everywhere?
All current browsers and most websites show WebP. Some older apps and upload forms still only take JPG or PNG; for those, use the WebP to JPG or WebP to PNG converter.
