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".

Отличный плагин. Много уже всяких перепробовал - то не сохраняют страницу после повторного запуска браузера, то открывают лишь часть .pdf файлов, а другие отказываются открывать с ошибкой. Этот работает без нареканий. Не знаю почему такая низкая средняя оценка, возможно, набрали в самом начале после релиза. Для меня сейчас все работает. Спасибо разработчикам!
love it, but it doesn't directly save to the original file path in the file system. i get that it's a api permissions issue. is there a helium browser fork with pdfjs? i might make my own if i dont find one
The only thing that fixed Chrome's lagging while scrolling on pdfs. Now it I can scroll without it looking like it was running on 15fps. Amazing.
All of the negative reviews seem to be from 2024 and prior. Some versions had glitches, apparently. I have been using the extension for about a year now, and for 2025-2026 and onward, this is my top pick for .PDF viewing, period. They make it so you aren't saddled with the default view imposed by the .PDF file's innate view preferences. Adobe and others do this silly thing where you are defaulted to view settings with an obnoxious space-wasting sidebar, useless AI features, etc. This one is more no-frills, and you get great consistency between .PDF files being loaded. This is particularly friendly for people who are viewing documents with known formatting or structure and want to whisk themselves right to where they need to be. Or, for comparing document versions and spotting changes/updates. Kudos to the devs.
It works
viewr로서 열었을때 화질이 깨끗하지 못함.
would be much much much better if if saving edited file is actually saving that file, not downloading the copy of that file in the download folder
ようやくChrome標準機能でPDFファイルを開けるようになったのでもう必要なくなりましたが お世話になりました
Does a much better job than the default Chrome viewing. It does save a separate edited file, which is fine once you know -but I do wish it could save in the same directory as the opened file. The highlighting on his selects the text instead of 'drawing' it with your mouse, which is AWESOME! I'm hoping it might get a "Save to Drive" icon like the default Chrome viewer just got -this would be SUPER amazing! Adding an image doesn't seem to work well for me, however. When I add one, it starts huge and slowly just keeps shrinking. If I try to drag to adjust the size, it just keeps shrinking from where I moved it to.
#1 It has one of the dumbest implentation of editing a PDF -- if you Edit a pdf -- you will want to save it, does it? No, it downloads a version of it into your downloads directory. Who will use such a dumb way of doing things -- the file is edited, means a copy of it should go where file was - not in the default chrome downloads directory. #2 I couldn't get it to show me the hand tool -- and why is is buried? why not put it on the top toolbar -- you have grabbed the space on the top of the screen -- use it, rather than hide the features in a menu on the right #3 Print implentation is awful - it dumps landscape documents to portrait settings! I wanted to like it because it's edit is better than edge -- but even that is missind drawing a line straight line with an arrow -- that's about 90% of the reason of using an edit on PDF .. but ony offer is to draw squiggly lines -- what a shame
