PDF Viewer Extension

PDF.js is a Portable Document Format (PDF) viewer that is built with HTML5.

PDF.js is community-driven and supported by Mozilla. Our goal is to create a general-purpose, web standards-based platform for parsing and rendering PDFs.

This extension offers PDF.js as the default PDF viewer in Chrome. This is the official Chrome extension of the PDF.js project. Be careful of unrelated copycats.

If you want to use this viewer to view local files, visit chrome://extensions/?id=oemmndcbldboiebfnladdacbdfmadadm and put a check before \"Allow access to file URLs\".

Please report any issues at https://github.com/mozilla/pdf.js/issues

Known issue: PDF files generated via a form (POST request) cannot be viewed.

Contains opt-out telemetry since version 1.5.285, see https://github.com/Rob--W/pdfjs-telemetry#privacy-policy

Christoph Thiede (ID: 0000002a93fc4255) Voted 4 ★ - Updated 10/07/2023 Great extension, much more convenient than built-in PDF viewer, just one feature request: Please make it possible to open a PDF in the built-in viewer anyway. Just for compatibility reasons. For example, I cannot use other extensions for summarizing the PDF etc. when viewing the PDF in this extension (extensions are not allowed to work on other extensions' pages). Otherwise great!
