Convert your PNG images to WebP in seconds. PNG stores every pixel exactly and keeps transparency, so quality is perfect — but files are larger than JPG or WebP. WebP usually beats both PNG and JPG on file size at the same visual quality and supports transparency, which makes it excellent for the web.
WebP keeps quality high while making files smaller, which is great for faster-loading websites.
How to convert PNG to WebP
- Add your PNG file. Drag and drop your PNG file onto the box, or click to browse.
- Output is set to WebP. The format is already set to WebP. Change it if you need a different output.
- Download. Click Convert and your WebP file downloads automatically.
PNG vs WebP
PNG is lossless and supports transparency — best for logos, icons, screenshots, and any graphic with sharp edges or a transparent background. WebP is modern, small, supports transparency — best for web images that need a small file size while keeping transparency.
Is it private?
Your PNG files are converted entirely inside your browser. Nothing is uploaded to a server, so your images stay completely private — and conversion is instant, even offline.
