Convert PNG to WebP for a faster website
Shrink PNG images by switching them to WebP while keeping transparency, then download them one by one or as a ZIP. The encoding runs locally in your browser.
Your files stay on your device: they are processed in this browser tab’s memory and never uploaded.
Lighter pages, better Core Web Vitals
WebP files are typically 25–35% smaller than equivalent PNG or JPG images. Serving WebP speeds up your pages, which helps Largest Contentful Paint and search rankings.
Transparency included
Unlike JPG, WebP keeps the alpha channel, so logos, product cut-outs and UI graphics stay transparent at a fraction of the PNG size.
FAQ
Which quality is best for WebP?
75–85 gives an excellent size/quality balance for photos; use 90+ for graphics with sharp edges and text.
Do all browsers support WebP?
Yes, every current browser displays WebP.
What can you do with an image converter?
An image converter fixes the everyday “this file won’t open” problem: designers turn WebP downloads into PNG for Photoshop, marketers shrink PNG screenshots into JPG for newsletters and switch site images to WebP or AVIF for faster pages, iPhone users convert HEIC photos to JPG for Windows and web forms, students and office workers combine photographed pages into a single PDF, and video creators prepare thumbnails, overlays and stills in the exact format their editor or platform expects — all without installing software or sending private images to a server.
