What are PDF and WebP files?
PDF (.pdf)
PDF is the universal format for sharing documents that must look the same everywhere. Fonts, images and layout are locked in, which is why CVs, certificates, admit cards, invoices and official notices are shared as PDF.
WebP (.webp)
WebP is a modern image format by Google that makes files 25–35% smaller than JPG or PNG at similar quality. It supports transparency and animation, and is used heavily by websites — which is why images saved from the web often end up as .webp.
Tips for the best WebP results
- A quality of 85–92% gives excellent results at a fraction of the size. Use the Image KB Converter if a form requires a specific file size.
- Use 150 DPI for screen viewing and sharing, 300 DPI for printing.
- Bookmark this page or install the app to convert PDF files offline next time.
Private by design: how this converter works
Unlike typical online converters that upload your file to a remote server, this PDF to WebP converter processes everything on your own device using PDF.js (by Mozilla), pdf-lib and other open-source libraries compiled for the browser. Your file is read into browser memory, converted, and offered back as a download — it is never sent to us.
- No upload wait — conversion starts instantly, even on slow mobile data.
- Private — safe for NID copies, certificates, bank statements and personal photos.
- No limits — no daily quota, no queue and no watermark.
- Offline-ready — once loaded, many tools keep working without internet.
