Why convert PDF to WebP?

PDF is the standard for documents, but web pages load faster with optimized image formats.

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

Add 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.

How much does a file weigh before and after PDF to WebP conversion?

We ran 4 PDF documents through this converter at the default quality of 90 percent: a photo on one page, a document with two scanned text pages and a screenshot, a screenshot with a photo on two pages, and two pages of vector text. Every page comes out as a separate WebP image at 144 DPI, so the table gives the document weight and the combined weight of all the images. We took the measurement ourselves on 11 September 2026 in a Chromium browser.

Test document	Pages	PDF weight	Combined weight of WebP images
Photo, 1 page	1	274.0 KB	297.6 KB
Two scanned text pages and a screenshot, 3 pages	3	613.3 KB	297.6 KB
Screenshot and photo, 2 pages	2	354.8 KB	406.5 KB
Vector text, 2 pages	2	12.5 KB	291.7 KB

Every one of our image format converters carries the same table with a real measurement. The tool shows the weight of your own file before and after conversion next to every row of the queue.

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.

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.

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 about 1190 × 1684 pixels, enough for a screen and a presentation but not for offset print.

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. Scans from a multifunction printer or a fax, black-and-white ones included, come out as complete page images, but their text stays part of the picture, so you cannot select or copy it.
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.

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.

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.
