I just needed it for viewing PDFs not to edit them, so, for me it works perfectly.

si il y avait une possibilité de mettre le contenu en français ça serait beaucoup plus pratique

Je ne comprend pas comment surligner le texte du pdf que j'ai ouvert, hors c'est pour cette raison que j'avais installer cette extension

Ivan Ivanov2023年11月11日

Заявлено - Convert PDF to JPG. Нет этого. Вообще нет никакой конвертации. Один обман.

es una mentira, no convierte ni hace nada...

No editing - just a rip off the established pdf.js project Reporting to Google and original developers. https://chrome.google.com/webstore/detail/pdf-viewer/oemmndcbldboiebfnladdacbdfmadadm https://github.com/mozilla/pdf.js

PDF Reader and Editor

Workflow & Planning

A general-purpose Portable Document Format (PDF) viewer based on Mozilla's PDF.js library

AI product read

Local PDF viewer and editor built on Mozilla's PDF.js, intercepting PDF files to render them within Chrome using HTML5

Provides a feature-rich, customizable PDF viewing experience directly in Chrome with offline support, dark/light themes, text-to-speech, and annotation tools, as an alternative to Chrome's built-in PDF viewer

User installs extension. When navigating to a PDF URL or downloading a PDF, the extension intercepts the response (via webRequest.onHeadersReceived) and redirects to its built-in viewer.html page powered by PDF.js. Users can also right-click PDF links and choose 'Open with PDF Viewer' from the context menu. The viewer provides toolbar controls for navigation, zoom, themes, text-to-speech, and annotation tools. Settings are configurable via the options page.

Target users: General Chrome users who need PDF viewing / Users who want a customizable PDF reader with themes / Users who need basic PDF annotation and signing / Users who prefer offline-capable tools

The extension bundles a large PDF.js library (~676KB pdf.worker.js, ~615KB pdf.sandbox.js) making deep manual code review impractical, but PDF.js is a well-known open-source Mozilla project
The donate button target URL (fastpdfviewer.com?rd=donate) was not fetched to verify if the destination website has paid plans, but this is irrelevant to the extension's functionality

Monetization

No paid features detected

The extension is entirely free. No payment UI, no subscription logic, no billing APIs, no feature gating found in source code. The 'Support Development' button on the options page opens the developer's website donation page (fastpdfviewer.com?rd=donate), which is voluntary and not a feature gate. The store description explicitly states annotations and highlights are 'all for free'. The 'license' and 'pro' keyword hits are false positives from Apache License headers in PDF.js library files and locale/translation strings.

Confidence: 92
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension operates entirely locally using Mozilla's PDF.js library to render PDFs in-browser. No login UI, no account creation, no authentication APIs, and no server-side user management code found. The 'auth' keyword hits in source are false positives from PDF.js library internals (author field in document properties, Apache License text). The 'jwt' hit is from Chrome's Web Store verified_contents.json signature file. No user credentials are collected or transmitted.
