Product summary

Review the store description, core capabilities, and common use cases.

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

当我设置为允许访问文件网址时，PDF文件就会被自动关闭；而如果我关闭，那么我再次打开PDF文件时，就要再重新选择要被打开的文件，麻烦了一步

Поставил, работает стабильно, запоминает последнюю прочитанную страницу и сразу на ней открывает. Процессор-память потребляет в допустимых пределах с моей точки зрения.

Very good. I can easily view PDFs of 300+ pages. Much better than the default.

Super Teil ... kann ich nur weiter empfehlen. Ich würde mir nur noch einen Tablet-Modus wünschen, wo die Oberfläche größer ist usw. Daumen hoch.
