About this PDF to WebP converter

WebP images are typically a quarter to a third smaller than JPG at the same visual quality, which makes them ideal for publishing PDF pages on a website. This tool renders each page and encodes it as WebP directly in your browser.

How PDF to WebP conversion works

  1. The PDF is opened locally with PDF.js.
  2. Selected pages are drawn at your chosen DPI.
  3. Your browser's built-in WebP encoder compresses each page at the quality you set.

Conversion quality: High fidelity. Pages are rendered exactly, then encoded as WebP at your chosen quality.

When to convert PDF to WebP

  • Showing brochure or catalogue pages on a website without slowing it down
  • Creating lightweight previews of documents in a web app

Limitations to be aware of

  • WebP encoding depends on your browser. Current Chrome, Edge, Firefox and Safari support it; very old browsers may not.
  • Some older desktop software can't open WebP files. Use PDF to JPG for maximum compatibility.

PDF vs WebP

PDF. PDF (Portable Document Format) stores pages with fixed layout, fonts and images so a document looks the same on every device. It is built for viewing and printing rather than editing.

WebP. WebP is a modern image format from Google that supports both lossy and lossless compression plus transparency. It is typically 25–35% smaller than JPG or PNG at similar quality and is supported by all current browsers.

Frequently asked questions

Are WebP images supported everywhere?

All modern browsers display WebP. Some older image viewers and office apps don't, so JPG remains the safest choice for email attachments.

What quality setting should I use?

Between 75% and 85% is usually indistinguishable from the original on screen while keeping files small.

Are my files uploaded?

No. This tool reads and processes files directly in your web browser. Nothing is sent to Expensico's servers, and the data is discarded when you close or reload the page.
