Why convert PNG to WEBP
WEBP delivers 25-35% smaller files than JPG or PNG at comparable quality and supports transparency. All modern browsers (Chrome, Firefox, Safari, Edge) support it natively.
Privacy and processing
PNG, JPG, and WEBP conversions run entirely in your browser using the Canvas API. The image never uploads to a server, which keeps the operation fast and your file private.
PNG to WEBP online with ImgShifter
PNG to WEBP is the workhorse conversion of web performance work. PNGs are the default export of screenshot tools and design apps, and they're consistently the heaviest assets on a page. WEBP stores the same image - including its transparency - in a fraction of the bytes, which is why every serious page-speed audit ends up recommending exactly this swap.
ImgShifter encodes WEBP with the libwebp encoder compiled to WebAssembly, running in your browser. Transparency carries over untouched, which is the decisive advantage over JPG for logos, UI elements, and product cut-outs. The size reduction depends on content: flat-color graphics commonly shrink 60-80%, and photographic PNGs even more, because WEBP can store them lossily instead of pixel-perfect.
Keep the original PNG as your editing master and treat the WEBP as the delivery format - browsers since 2020 (including Safari 14+) all display it. And as with every browser-side ImgShifter tool, the conversion runs identically with your network disconnected, which is the simplest proof your files stay local.
