PDF to WebP Converter

This PDF to WebP converter saves each PDF page as a WebP image at 72, 150 or 300 DPI, with a quality setting from 10 to 100. WebP files are usually much smaller than PNG or JPG files of the same page, which makes them a good fit for websites, blogs and online shops.

Convert every page or only the pages you pick, on a white or a transparent background. One page downloads as a single .webp file and two or more come as one ZIP. Your browser draws and encodes the pages, so the PDF is never uploaded and there is no account, page limit or watermark.

A PDF can't be shown inline on most web pages, so a page that needs to appear in an article, a product listing or a help centre has to become an image first. Google designed WebP for images on web pages, and its published compression study found lossy WebP files 25 to 34 percent smaller than JPG files of similar quality.

Smaller images load faster, and the largest image on a page often sets its Largest Contentful Paint time in PageSpeed Insights. WordPress has accepted WebP uploads since version 5.8, and Shopify and Wix take them too.

Quality decides how much detail the encoder may drop to save space. Pages with text and flat colour stay clean at lower settings than photos do, because most of the page is plain background.

DPI is the number of pixels per inch of paper. Doubling it doubles the width and the height, so the image has four times the pixels. For the web, 150 DPI is a good start, since a 1240 pixel wide A4 page still looks sharp on a laptop screen. Use 72 DPI for thumbnails and 300 DPI when readers need to zoom.

WebP images can't be wider or taller than 16,383 pixels, and some phones refuse to draw canvases over about 16.8 million pixels. Pages over that size are drawn at the highest DPI that fits. A3 at 300 DPI, for example, comes out at about 295 DPI, and the result screen tells you when this happened.

The tool uses the WebP encoder built into your browser. Chrome, Edge, Firefox and Opera on Windows, Mac, Linux and Android can all save WebP. Safari can display WebP, but at the time of writing it hands back a PNG when a web page asks it to save one. Most browsers on iPhone and iPad use Safari's engine, so they behave the same way.

The tool tests the encoder as soon as you add a PDF. If your browser can't make WebP, the options panel says so and the convert button stays off, so you never download PNG files with a .webp name. If a later Safari version adds WebP saving, the test passes and the tool works there too. On an iPhone, use PDF to PNG or PDF to JPG instead, or run this tool on a computer.

Each WebP is a picture of the whole page, so the text in it can't be selected or searched. Add the important words as alt text or as real text on your web page. To keep editable text, use PDF to Word or PDF to Text.

If the PDF asks for a password to open, remove it with Unlock PDF first. PDFs that only block printing or copying open without a password. All pages are kept in memory until the ZIP is built, so for a very long PDF at 300 DPI, convert it in a few page ranges.
