PDF.js is part of Firefox since version 19. The Firefox extension is not supported and marked as disabled for Firefox versions 35 and up. To install the Chromium extension, please refer to the README. The Chromium extension is maintained by a PDF.js contributor. Which browsers have extensions (and where can I find install procedures)? Too many features are missing to be supported. For mobile only iOS 10 and higher are supported. Some missing features/defects have been reported, but no problems in general. ![]() However, this support will be dropped after stable version 2.6.347. Some functionality/features may not be available and the performance will be worse compared to modern browsers. If no version is indicated, then the latest desktop/mobile versions are intended. Find the list of features needed for PDF.js to properly work and browser tests for those features at Required Browser Features. The objective is to support all HTML5 compliant browsers, but since feature support varies per browser/version our support for all PDF features varies as well. However, we also provide the translated/polyfilled build for older browsers in a separate bundle (with the -es5-dist.zip suffix). Please notice that generic/demo viewer blocks this functionality if deployed not on domain to avoid content spoofing (see ).įrom version 2.4.456 on we produce a non-translated/non-polyfilled build for modern browsers by default. There are some possible ways to get around this such as using CORS (see also unsafe headers issue and Access-Control-Expose-Headers issue) or setting up a proxy on your server that will feed PDF.js the PDF file (example: ). PDF.js runs with the same permissions as any other JavaScript code, which means it cannot do cross origin requests (see Same origin policy and an example). (The base64 conversion operation uses more memory, so we recommend delivering raw PDF data as typed array in first place.)Ĭan I load a PDF from another server (cross domain request)? If you have base64 encoded data, please decode it first - not all browsers have atob or data URI scheme support. You can use raw binary data to open a PDF document: use Uint8Array instead of URL in the PDFViewerApplication.open call. Use PDFViewerApplication.open(file) to load the PDF file later. The viewer can be started without any PDF loaded by setting the defaultUrl app option to an empty string or by using the ?file= query string without any location specified. In the latter case, the PDF path/URL must be encoded using encodeURIComponent(). You can modify the defaultUrl app option in the web/app_options.js file or you can append the ?file= query string to the viewer URL, e.g. What types of PDF files are slow in PDF.js?
