When to use it
If the PDF pages are headed for a website - embedded slides, documentation figures, report previews - WebP is the right target: sharper than JPG at the same size and dramatically lighter than PNG. Rendering runs entirely in your browser, so the document itself never travels.
- Embed slide-deck pages on a webpage without the PDF viewer weight.
- Publish documentation figures extracted from spec PDFs.
- Preview report pages in a web app at minimal bandwidth.
