• (2023-10-30) Yousef Alaa: works great
• (2023-10-24) Liu Andy: 在文件夹打开PDF跳转到Chrome怎么还要选择文件？这样太麻烦了。
• (2023-10-07) Christoph Thiede: Great extension, much more convenient than built-in PDF viewer, just one feature request: Please make it possible to open a PDF in the built-in viewer anyway. Just for compatibility reasons. For example, I cannot use other extensions for summarizing the PDF etc. when viewing the PDF in this extension (extensions are not allowed to work on other extensions' pages). Otherwise great!
• (2023-09-26) Timon Saalbach: funktioniert soweit einwandfrei. Leider sind die gedruckten Dateien aber sehr unscharf.
• (2023-09-23) Oscar Rego: man I went through so many pdf viewer extensions and this by far works among all of them
• (2023-09-01) Lộc: good
• (2023-08-25) Kanan Hasanov: Why didn't you add the background customization? It'd be better if you added this feature, 'cause I hate reading the text with white background at night.
• (2023-08-14) El detective Yoshi: Super para evitar descargarlos en todo momento
• (2023-08-07) Nicole Ahmed: The official pdf js extension. Sets the default pdf viewer in chrome to this. Can open local files if you allow access to file urls in settings. Highlighting works well (but only persists if you download your edited file). Remembers position on returning to url. Excellent.
• (2023-07-01) Андрей Зайченко: Почему при изменении масштаба для печати содержимое файла оказывается по центру листа? До недавнего времени всё было нормально- уменьшаешь масштаб, изображение печатается сверху. Можно ещё что-то напечатать на оставшемся месте. Теперь- печатается по центру, лист больше нельзя использовать. Где ваша забота о Экологии?
• (2023-06-25) Mohammed Yasin: Thanks for the new update.
• (2023-06-23) Che Cosa??: excellent, buth i would like to be able to highlight things. im having some problem with the highliter, when i highlight something and then zoom out the marks move from the position.
• (2023-06-04) Syed Bilal Alam: Very Excelent extension for chrome users loved this extension I came to know about this extension from stckoverflow and the experince is awesome this my primary pdf viewer now
• (2023-05-23) Nickolay Romensky: I moved from Adobe Reader to this chrome extension due to many annoying bugs. I need only two things - (1) display the PDF and (2) remember the page when I open it next time. from my experience the (1) works very well, but the (2) does not always work, in most cases it show page which I read few days ago. dear developers, please fix this essential feature computers and IT in general are our biggest problem, I do not think people are able to write 100% error free code
• (2023-05-10) bich ngoc: Very good
• (2023-04-20) Pablo Infanta: Me gusto
• (2023-04-04) socalled chou: first，i want to edit pdffiles,.. besides, it's a monster app. when i work on webside, quite a lot of pages will jump out when the webside has any sheet.
• (2023-03-05) Erick Leon: Pretty good, I think the smart paste extension has the most updated version of pdf.js
• (2023-02-24) Eric Townsend: 0 issues or problems. Smooth, fast, not sure why it has such a low rating.
• (2023-02-07) Ильдар Мирный: Отличное расширение! Спасибо.
• (2022-12-22) Erik Isberg: Recommended software. Solved one of the major problems with chromebooks for me. All other pdf viewers I have tried are utterly due to excessive lagginess, seconds and more. This one updates pages OK, also seems to do a much better job of navigating page numbers.
• (2022-11-23) Rick Yoder: Out of date. The latest PDF.js has newer features. This extension hasn't been updated since 2019!
• (2022-11-13) Milad kb: You can start from where you red the last page 5/5!
• (2022-11-11) Ian Pan: As many mentioned, I'm surprised by the low rating. This extension makes PDF scrolling much much smoother in Chrome, on par with Edge's PDF support (which has always been better than Chrome).
• (2022-11-05) wgh: This software will degrade the resolution of pdf when I want to print pdf file. Please fix this bug. please don't convert pdf to canvas when click the printer button.
• (2022-09-16) Aniruddh Deshpande: This works perfectly! Chrome default pdf viewer is laggy while Microsoft Edge seemed to have a very smooth refresh rate. This extension changed that. I don't know why the rating is so low. The only con is that the pinch zoom (touchpad) is very sensitive so its better to use Ctrl +/-.
• (2022-08-30) Radu Leonte: I dont use Acrobat or other softs. This is my preffered way of opening PDFs. Does anything i need, i can rotate, the pages are numbered both in roman (i, ii, ix etc) and arab (1, 2), displays chapters on the sidebar, can zoom in and out easily. 10/10
• (2022-06-24) John Sebok: Works great and works with relative links within PDFS which most embed browser PDF views won't do.
• (2022-06-24) Jonathan Schroeder: pay no attention to the spam bots, this extension is solid.
• (2022-05-26) qi liu: 很好用，是否可以增加夜间模式吗，或者自定义背景和文字颜色的功能吗。 Good job, Can you add dark mode, or functions of customizing background and text color.
• (2022-05-24) Jonas Elias: funciona perfeitamente
• (2022-04-28) Mahdi Hazrati: خیلی خوب بود
• (2022-04-25) Jordy Beltre: Uff 10/10
• (2022-04-17) Андрей Булыгин: Don't know why rating is so low. For me it works better than default chrome pdf viewer.
• (2022-04-07) Dennis Lee: 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.
• (2022-04-05) ziu C: 很棒，比Chrome自带的PDF预览工具滚动更流畅、加载更快。 :)
• (2022-03-15) Husru: "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.
• (2022-03-13) davidhcefx (David): 五星好評！太強大了，而且還是開源的，可以丟掉 Adobe 了。
• (2022-03-01) Toby Wilson: need for update 2022
• (2022-02-17) Will Hunt: 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
• (2022-02-03) Andrey Kirchev: Man kann nicht beim herunterladen den Zielordner wählen !!!
• (2022-01-22) Артём Васёв: Позволяет сохранить иногда не сохраняемые пдф файлы с сайтов для чтения оффлайн. Спасибо.
• (2022-01-22) Turtles yay: 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.
• (2022-01-19) Edison Martins Cavalcanti: Que aplicativo ruim é esse?
• (2021-12-22) Furio Petrossi: Ottima, vorrei fosse aggiunta l'opzione di caricare files direttamente dal visualizzatore, opzione esistente nella versione originale.
• (2021-11-29) Paul Schmied: It works OK , not great. Better for opening and viewing smaller PDFs, but the oddities are annoying. It doesn't work at all when viewing Drive through the Chrome browser. Opening the same exact Drive files with the Files app, it opens them at the selected optional zoom setting, but when I swtch to an internally indexed page, it changes the view to "automatic" .
• (2021-11-28) David Cyrus: It works great! I'm surprised with the extension's low rating.
• (2021-11-17) Picchio Knossus: The low ranking of the reviews put me off initially. Just try it out. People that are giving low rankings are probably using 1080p monitors therefore on their system the default pdf viewer bundled in chrome works just fine and when they look around for a different pdf viewer it is likely because they want more functionality. This extension is not aimed at them. This extension is aimed at people with 4k-like monitors that are frustrated by the unusable performance of the default pdf viewer but still want to be able to view pdf files in a browser rather than always downloading them to use the pdf viewer they have installed on their system. Having said that this extension still offers more functionality than the default one so you may like it even on lower resolution monitors.
• (2021-10-06) aparioss: Great Actually replace the default Chrome PDF viewer Include an option to resume reading PDF files where left off.
• (2021-09-01) McKey McCrae: I do love the extension but, I wish you could block certain websites from using it instead of allowing certain ones. I have a far shorter list of sites I don't want to use the extension on and it would be easier to just block those

• (2023-04-17, v:2.3.164) Harsh Arora: Laggy zoom

If I disable this extension I can download the pdf without problems. Is there a posiblity about a url list where this extension is disabled? "Disable this plugin in this website" or something similar. Again, thank you for your work.

  Hello, On Mac, the shortcut "Command F" triggers "Find in document". With this extension, the shortcut "Command Shift F" also triggers "Find in document". However, Chrome on Mac already uses "Command Shift F" for a different shortcut ("Always Show Toolbar in Full Screen"), and this extension prevents users from using that shortcut. I would call this a bug. This extension uses two different shortcuts for the same action, blocking a commonly-used default Chrome shortcut. Please change this behavior. Thank you, Zach Siegel

It seems to be only one type of PDF, because it happens consistently when the PDF is from one source, but not another. Like I said, it just started happening from this source within the last 2 days which makes me think something has changed, like an update. Any help would be appreciated.

However, a feature that Internet Explorer has that i can't get away from is using the mouse wheel to zoom in on the .PDF without having to hold down the control key. Then the left mouse button, if you push and hold it down, it pans around in the .PDF. is there a setting that i can switch the wheel to zoom instead of scrolling up? Thanks!
