About PNG
PNG (Portable Network Graphics) is a lossless image format created in 1996 as a free replacement for GIF. It supports full colour and an alpha channel for transparency.
Screenshots, logos, icons, diagrams and any image with text or sharp edges.
For photos a PNG is several times larger than a JPEG, and plain PNG has no animation (that is APNG).
Convert PNG to WebP online free, no account required — WebP is Google's web image format with lossy or lossless compression.
Change PNG to WebP without losing quality — convert PNG to WebP free in your browser.
Why is my PNG so much bigger than the same photo as JPG? PNG stores every pixel losslessly, which is ideal for screenshots and graphics but wasteful for photos — JPG or WebP compress photographs far more efficiently.
About WebP
WebP is an image format released by Google in 2010. It supports lossy and lossless compression, transparency and animation.
Websites use it to serve images smaller than the equivalent JPEG or PNG; all current browsers display it.
Some older desktop software and many print services still do not accept WebP files.
Why convert images to WebP? It cuts file sizes by a quarter to a third compared with JPG at the same quality, and every current browser displays it.
What changes when you convert PNG to WebP
- The PNG picture is re-encoded as WebP at the default quality settings, so it looks close to the original but is not bit-identical.
Settings you can change
Before you convert PNG to WebP, you can adjust: Width, Height, Scale fit, Crop position, Never enlarge, Quality, Lossless, Progressive, Remove metadata, Auto-orient from EXIF, Rotate, and Background.

Each plan sets a maximum file size and a number of conversions per day, and video and audio files also have a maximum length. Guests can convert files up to 100 megabytes and 5 per day; a free account raises this to 500 megabytes and 25 per day; paid plans go up to 100 gigabytes.
Your converted WebP file is kept for 2 hours, then deleted.
