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".

- (2025-05-13) Manuel Sitton: Works fine, but would really love a translation option
- (2025-04-10) Foong Yihao: Loved it. It works as expected. PDFs are now no longer required to be downloaded to view them
- (2025-04-06) Hystri Onic: I love it, it would be even better if they included a "Save as" button, in addition the existing "save" one
- (2025-03-07) Xythes Bwuaghl: After closing and reopening Chrome and reopening last session (ctrl+shift+T), the PDF tabs are gone and become "new tabs".
- (2025-02-26) Mansoour Alshahrani: been struggling with Arabic text pdf for months while it works perfectly in Firefox. this solves my problem and hassle cuz it use Firefox approach
- (2025-02-15) Ferit Kenan Eyüpreisoğlu: You can have the Firefox PDF reader in Chrome with this extension.
- (2025-02-03) Tanveer Ul Mustafa: I always had the issue that there are some pdfs that chrome forces to download even when the privacy settings have been set to open instead of download. This takes care of them just fine. Great job.
- (2025-02-01) Flavio Picci: Good PDF viewer, great ownCloud integration
- (2024-11-27) Leo Li: The only usable, and great PDF alternative for default Chrome built in PDF viewer! Faster, Lighter, and Smoother!!! If the extension can download the pdf automatically and open pdf at the same time, just like what Firefox do, that's would be even better!
- (2024-11-20) Muhammad Fadhlan Karimuddin: best lightweight pdf viewer and annotator available
- (2024-10-22) Radu Hociung: It's a better PDF reader than the built-in one, but it changes the URL in the address bar, making it fiddly to cut-and-paste. I am removing it for now because I cut-and-paste the URL a lot for citations.
- (2024-09-25) Chikuwa_25: very smooth
- (2024-09-23) Chathindu Bandara: Does what's advertised, never had any problems. Sometimes, it takes a while for pages to load just after opening Chrome, but I think it's coz my PC's really slow, not really the fault of the extension.
- (2024-09-22) Osama Khan: A perfect pdf viewer. now actually i can use read pdf online
- (2024-09-14) Mohammed Yasin: The new update broke it.
- (2024-09-14) Mohammed Yasin: The new update broke it.
- (2024-09-12) Emorch: This extension has always worked pretty good for me, yesterday it did break but I feel bad since it got hate-bombed so I'll give it a 5 now
- (2024-09-11) Eduardo Pereira: It stopped working in Opera, any chance of releasing it for use in that browser?
- (2024-09-11) Eduardo Pereira: It stopped working in Opera, any chance of releasing it for use in that browser?
- (2024-09-10) Boudjelida Abdelhak: works perfect, best extension ever
- (2024-09-10) Haoming: Can the authors add a feature that can turn off prompting before downloading pdf files?
- (2024-09-09) stella: As of today it is forcing me to download the file first instead of simply opening the pdf in a new tab.
- (2024-09-09) Rui | FX: Not working now... please update this very usefull extention :)
- (2024-09-09) Aleksej Stankovic: It is not working since 09.09.2024.
- (2024-09-01) Eugene Kardasis: Worked well until recently. Instead of opening pdf links in a tab, now I often get prompted to download, which is the main thing I want to avoid - cluttered downloads.
- (2024-08-02) Frank Utne: This is the PDF extension you want to install. It 'just works'. It gives me exactly what I want. Full page view, same shortcuts as Acrobat. I made the big mistake of installing the Adobe Acrobat extension. All I wanted was a PDF viewer that behaved like Acrobat, meaning that I could get a full page view and use Acrobat shortcuts to navigate. But no, I got a tiny multipage view with no shortcuts. Typical complete Adobe fail. I uninstalled it immediately and installed this extension instead.
- (2024-07-15) Thomas Lynch: No dark mode. Blocks 'Dark Reader' with 'This page is protected by browser'
- (2024-07-05) Mark W: made my laptop useable again
- (2024-06-23) Til Mohr: Works great! The default PDF viewer in Chrome is complete garbage. This extension brings the Firefox PDF viewer to Chrome. I only wish it would not change the favicon of the tabs - distinguishing between multiple PDFs is now a tiny bit more difficult.
- (2024-06-21) D A: I can't get it to work on files I've downloaded, or on anything else. It sux.
- (2024-05-16) Eric Otley: This is amazing!
- (2024-04-28) Tom Molla: Just installed it and it works great.
- (2024-04-13) Tech Hub: I downloaded it, it worked perfectly and suddenly stopped days after.
- (2024-04-13) Brian Szuter: I started using this because I saw that this PDF Viewer remembers where you left off when reading a PDF. It works great, and can be easily set as the default PDF Viewer on a Chromebook. Highly recommend!
- (2024-03-31) Mark: I downloaded this on my 2022 macBook, because the standard viewer that comes with chrome would not download files. I can't figure out how to get chrome to use it when there is a pdf to be viewed. When selecting the extension, it brings up the viewer with a sample PDF which can be downloaded, but how to use it to open up URL's??
- (2024-03-29) Sigma F: I guess this is the best pdf viewer for scientific reasercher, because it supports 'commond+[ '。
- (2024-03-11) Jason Jiang: Works great - has great UI that makes it easy to get started and explore what it can do.
- (2024-02-28) Suresh Balaji: i works good but it does not change pdf logo in file location as it change in edge browser which is convenient to identify the document where in chrome it just show chrome logo in pdf files, bad to use
- (2024-02-20) Robert Davis: Just installed, seems to work pretty good so far. It's rendering documents much faster than Adobe.
- (2024-02-17) Ying Wang: Best pdf viewer in Chrome web store.
- (2024-01-04) Justin Hutchins: Half of the text on the pdf is in weird characters, needs some work. happens from multiple sources
- (2023-12-31) Patrik Plachy: Great tool! Everything I need, including that extension remembers the last page I were reading before closing the document...
- (2023-12-31) Brian Shui: Great Tool to use!
- (2023-12-18) Leo Li (liaj): Very Very useful extension! The default built in PDF viewer sucks! This extension even better than the built one! more smooth, more efficient! It allows Chrome to opens PDF urls automatically.
- (2023-12-06) Sandi “La Chica Maravilla”: So, my 5-star review is because after spending almost 2 hours hassling with 3 different options, I found out that this extension, allows me to add text to a pdf file, I can change the color and size of the font - not the font itself but hey, it's free. I am in love with this extension now and highly recommend it for adding text. Hope this helps others decide.
- (2023-12-06) Subvert: This pdf viewer extention both is super convient for me who hates the default pdf viewer for d2l and it even bypasses crtl + c protection allowing me to with much more ease create flashcards on knowt. Thank You
- (2023-10-30) Yousef Alaa: works great
- (2023-10-30) Yousef Alaa: works great
