Product summary

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

Very fast and displays well, just that some download links gets opened instead. Not sure if it's another extension or the environment interacting with this one.

"Long Strip Margin" los pdf tienen una separacion de pagina, saben como hacer para que esa separacion sea 0 ? Los que leen manga me entenderan.

五星好評!太強大了,而且還是開源的,可以丟掉 Adobe 了。

I got it to speed up scrolling from very laggy on 4k screen and it did a great job. Scrolling is much faster now, way better

It's good but the font is so atrocious that I sometimes have to turn it off to be able to read the text. What's with those random spaces in between letters and why are they sometimes the same size as the spaces in between words? Why are some letters on top of each other? (Is there a way to change the font to a better one?) Other than the font, this extension works really well.

Ottima, vorrei fosse aggiunta l'opzione di caricare files direttamente dal visualizzatore, opzione esistente nella versione originale.
