Why convert PDF to WebP?

PDF is the standard for documents, but web pages load faster with optimized image formats. WebP offers 25–35% better compression than JPG at equivalent quality, making it ideal for embedding PDF page images on websites, blogs, and documentation.

Each PDF page becomes a separate WebP file. WebP supports both lossy and lossless compression. It is supported by all modern browsers (Chrome, Firefox, Safari 14+, Edge). For maximum compatibility with older browsers, consider converting to JPG or PNG instead.

This converter processes files locally in your browser — nothing is sent to any server. No registration, no limits, no watermarks.

How to convert PDF to WebP

Upload your PDF file
Drag and drop your PDF file onto the converter or click to browse.
Set the quality
The Set WebP quality slider takes values from 60 to 95 percent, default 90. Every page is rendered at 144 DPI. Then click Convert.
Download the images
The Download button next to a page saves it on its own, and Download all packs all pages into one ZIP archive.

What makes this converter different?

Complete privacy
Your files are processed entirely in your browser. Nothing is uploaded to any server.

All pages at 144 DPI
The converter renders every page of the document at double scale, that is 144 DPI, and shows the size of the result next to it.
Download in one archive
The Download all button packs all finished files into one ZIP archive, so you do not have to approve a dozen downloads one after another.

The quality slider when converting PDF to WebP

The Set WebP quality slider takes values from 60 to 95 percent and sits at 90 by default. Every page is first rendered at 144 DPI and then saved at that quality. In the measurement the screenshot page came out as 49.6 KB and the photo page as 543.4 KB.

90 percent (default): presentations and documents where the text has to stay readable.
80 percent: web publishing and email attachments.
60 to 70 percent: thumbnails and page previews.

Save text-only pages as PNG: no artefacts around the letters, though in a larger file.

Resolution and weight of images from PDF pages

The converter renders every page at double scale, that is 144 DPI: an A4 page gives an image of 1190 × 1684 pixels, enough for a screen and a presentation but not for offset print. From the two-page test PDF the screenshot page came out as 49.6 KB and the photo page as 543.4 KB.

The Set WebP quality slider, 60 to 95 percent (default 90), changes weight and sharpness: go down to 80 for the web. At the same quality WebP comes out lighter than JPG and keeps sharp text better.

Tips for converting PDF to WebP

A few tips to help you avoid common issues during conversion:

Very large files
The converter renders every page separately and keeps the finished images in the browser’s memory until you download them. Convert a document with several hundred pages, or with high-resolution scans, in a few rounds: download the finished pages with Download all and only then add the next file. The limit is 100 MB per file.
Pages with text
At 144 DPI the text is readable on screen, but small print loses sharpness when enlarged. To publish part of a page in print, export the image from the program that created the PDF.
Transparency
WebP stores an alpha channel, so transparent and semi-transparent areas of the PDF file stay unchanged in the result.
The document stays untouched
The page images are new renders and the PDF file does not change in any way. To cut one page out as a separate PDF use a document program; this converter saves images only.

How much does a file weigh after converting PDF to WebP?

A two-page test PDF: page 1 holds a 1920 × 1060 pixel screenshot, page 2 a 1280 × 1659 pixel photo. The converter renders every page at double scale, that is 144 DPI and then saves it at 90 percent quality.

File	Image dimensions in pixels	WebP
Page 1: screenshot	1684 × 1190	49.6 KB
Page 2: photo	1190 × 1684	543.4 KB

Our own measurement from 6 September 2026 in a Chromium-based browser. The size of a page depends on its content: a screenshot with large flat areas comes out several times lighter than a photo.

When to choose WebP vs JPG vs PNG for PDF page extraction

WebP offers the best balance of quality and file size for web use. Files are 25–35% smaller than JPG at equivalent quality and support both lossy and lossless compression modes.

Choose WebP when the images will be displayed on websites or shared digitally. Choose JPG when you need maximum compatibility (older devices, email clients). Choose PNG when you need lossless quality (documents with text, technical drawings).

WebP is supported by all modern browsers (Chrome, Firefox, Safari 14+, Edge). For the few remaining users on very old browsers, serve JPG as a fallback using the HTML <picture> element.
