选择适合您所有需求的适用于Windows的正确(Windows)PDF并不是一项艰巨的任务。对于不同程度的有用性，有很多选择。就基本的PDF 阅读(PDF reading)要求而言，通常只需要当今的 Web 浏览器即可。他们已经做了大多数免费PDF阅读器可以做的事情。
尽管如此，对于那些寻找具有可以执行某些任务（例如注释、数字签名、表单填写等）的高级功能的(form filling)PDF的人来说，了解可用的选项可能会有很长的路要走。
特别是对于非常流行的操作系统(operating system)Windows 10，有相当多的PDF阅读器可供选择。正因为如此，我们决定编制我们的个人列表，其中 7 个Windows PDF阅读器是 2019 年最好的免费 PDF 阅读器，进入 2020 年。
适用于 Windows 的 7 个最佳 PDF 阅读器(The 7 Best PDF Readers For Windows)
根据您的 PDF 需求，此列表可能会因按特定顺序列出选项而令人困惑。因此，相反，我们决定列出最好的整体免费 pdf 阅读器，您可以从 7 个中决定哪一个最适合您。
可能这个列表中最强大的程序必须是Adobe Acrobat Reader。它也是满足基本和高级功能需求的PDF 软件(PDF software)中最受欢迎的选择之一。建议将此特定程序用于所有PDF任务，因为遇到需要高级PDF 阅读器的(PDF reader)PDF 文件(PDF file)的情况并不少见。
Adobe Acrobat Reader看起来像是一个臃肿的产品，尤其是与此列表中的其他产品相比，但那是因为它是唯一一个可以解决所有PDF相关问题的产品。它是列表中最有用的软件，可以找到其他PDF(PDFs)可能无法解决 的PDF需求的解决方案。(PDF)
有不同的阅读模式、文本突出显示(text highlighting)、添加注释和处理填写表格的能力、允许数字签名、印章等等。对于多个PDF文件，Adobe支持选项卡式视图，允许您同时打开和阅读这些PDF文件。关于这一切的疯狂部分是该产品的基本版本是完全免费的。

PDF-XChange 编辑器(PDF-XChange Editor)(PDF-XChange Editor)
如果您碰巧在市场上想要更精简的东西，PDF-XChange Lite是(PDF-XChange Lite)Windows 10的免费PDF 阅读器(PDF reader)替代品。PDF-XChange 品牌(PDF-XChange brand)进行了彻底的改造和简化(revamp and simplification)，将名称中的“查看器”替换为“编辑器”，因为原版没有免费提供基本的编辑功能。
随着这些变化，它现在提供了一个适当命名的轻量级体验和功能，用于在(experience and features)PDF 文件(PDF file)中阅读、打印、注释、保存图像和文本等。除了开发人员声称免费版本将提供 60% 以上的付费版本之外，这使得PDF-XChange Lite成为(PDF-XChange Lite)PDF 阅读器类别(PDF Reader category)的一个很好的入口。
苏门答腊PDF(SumatraPDF)(SumatraPDF)
SumatraPDF是轻量级前端的另一个条目，它是一款开源PDF 阅读器(PDF reader)软件，适用于从Windows 10一直到 XP 的 Windows操作系统。(Windows)
自然，任何标有开源标签的产品都意味着免费且对公众开放，同时保持可定制启动的产品。SumatraPDF在(SumatraPDF)GPLv3(GPLv3 license)许可下获得许可，不仅支持PDF 格式(PDF format)，还支持EPUB、MOBI、FB2、CHM、XPS和DjVu格式。
当然，SumatraPDF虽然提供了出色的阅读体验(reading experience)，但确实缺乏功能。毕竟是精简版。它不附带注释、文档签名(document signing)和表单填写，有些人可能会认为这些是破坏交易(deal breaker)的。但是，如果您追求的是轻量级，那么SumatraPDF采用 64 位安装程序，大小不超过 5MB。
标枪 PDF 阅读器(Javelin PDF Reader)(Javelin PDF Reader)
在寻找具有PDF 阅读器所需的所有基本特性和(PDF reader)功能(functionality one)的软件时，Javelin 应有尽有(Javelin)。最起码，Javelin超干净的界面和全屏、并排、连续等多种屏幕查看功能，能让你轻松完成所有日常琐事。

除了Adobe ，办公生产力软件(office productivity software)世界中最知名的名字之一是Nitro Reader。如果您正在寻找一款试图在可用性和提供的功能之间取得完美平衡的免费PDF 阅读器，就是这样。(PDF reader)
您不会发现过多您不太可能使用的不必要功能。取而代之的是，Nitro Reader提供了更多严肃风格的PDF 阅读器(PDF reader)，其流畅的界面模仿了直接来自Microsoft Office 套件(Microsoft Office suite)的应用程序之类的功能。

福昕阅读器(Foxit Reader)(Foxit Reader)
福昕(Foxit) 阅读器既强大又免费，为市场上大多数人对(Reader)PDF 阅读器(PDF reader)的追捧潜力创造了双重打击。Foxit与Adobe 和 Nitro一样，是(Adobe and Nitro)文档阅读器软件(document reader software)领域的全球知名品牌(name brand)，并且比两者都轻。
Foxit的官方网站设计精良且易于浏览，提供了可靠的下载体验(download experience)，而无需像Adob(Adobe) e 那样推送额外的臃肿软件。他们还引入了在线ConnectedPDF 文档管理系统(ConnectedPDF Document Management System)，它不会尝试向您的 PC 发送一些额外的过时软件。

随着 8.0 的更新，Foxit还推出了新的在线ConnectedPDF 文档管理系统(ConnectedPDF Document Management System)，为您的PDF文档提供在线安全性和保密性(security and confidentiality)。这在在线协作时会派上用场，有助于保持文档井井有条。

自称是“世界上最小的桌面PDF 阅读器(PDF reader)”，SlimPDF是另一个轻量级阅读器(lightweight reader)。下载大小(download size)仅为 1.43MB，很难反驳这一说法。这使得它非常适合拥有旧型号计算机的任何人，这些计算机可能在运行更复杂和繁重的PDF 阅读器(PDF reader)时遇到问题。

The 7 Best PDF Readers for Windows In 2020
Choosing the right PDF for Windows that suits all of your needs isn’t too difficult a task. Therе are many options to varying degrees of usefulnesѕ. As far as basic PDF reading rеquirementѕ are concerned, today’s web browsers аre often all that is needed. They alreadу do what most free PDF readеrs can do.
Still, for those looking for a PDF with advanced features that can perform certain tasks such as annotation, digital signature, form filling, etc., knowing what options are available can go a long way.
For Windows 10 in particular, a very popular operating system, there are quite a lot of PDF readers from which to choose. It’s because of this that we’ve decided to compile our personal list of which 7 Windows PDF readers are the best free pdf readers of 2019, heading into 2020.
The 7 Best PDF Readers For Windows
Depending on what your PDF needs are, this list could seem confusing by listing off options in a particular order. So, instead, we’ve decided to list the best overall free pdf readers where you can decide out of the 7 which one is best for you.
Possibly the most powerful program on this list would have to be Adobe Acrobat Reader. It’s also one of the most popular choices in PDF software for both basic and advanced feature needs. This particular program is recommended for all PDF tasks as it is not uncommon to come across a PDF file that demands an advanced PDF reader.
Adobe Acrobat Reader can seem like a bloated product, especially in comparison to the others on this list, but that is because it is the only one that has a solution for everything PDF related. It’s the most useful software on the list, finding solutions to your PDF needs where other PDFs might fail.
There are different reading modes, text highlighting, the ability to add notes and handle filling forms, allows for digital signatures, stamps, and so much more. With multiple PDF files, Adobe supports a tabbed view, allowing you to open and read those PDF files simultaneously. The crazy part about it all is that the basic version of this product is completely free.
While using one of the other free PDF readers, you may notice that larger files may not process fully. Adobe Acrobat Reader doesn’t have this problem. No matter the size of the file, it will be easily compiled and processed, providing a readable PDF for your viewing every time.
If you happen to be in the market for something more lite, PDF-XChange Lite is a free PDF reader alternative for Windows 10. The PDF-XChange brand has undergone a complete revamp and simplification, swapping out “Viewer” for “Editor” in the name, as the original didn’t offer basic editing functions for free.
With the changes, it now provides an appropriately named lightweight experience and features for reading, printing, annotating, saving images and text, etc. all within a PDF file. This, on top of the developers’ claim that the free version will ship with more than 60% of what you’d get from the paid version, makes PDF-XChange Lite a great entry into the PDF Reader category.
Another entry on the lightweight front, SumatraPDF is an open-source PDF reader software available for Windows operating systems ranging from Windows 10 all the way back to XP.
Naturally, anything labeled with open-source means a product that is free and open to the public while remaining customizable to boot. SumatraPDF is licensed under GPLv3 license, and not only supports the PDF format but also the EPUB, MOBI, FB2, CHM, XPS, and DjVu formats as well.
Of course, SumatraPDF, though it provides an excellent reading experience, does suffer from a lack of features. It is lite after all. It doesn’t come with annotations, document signing, and form-filling which some may consider a deal breaker. However, if light is what you’re after, SumatraPDF comes in a 64-bit installer that is no larger than 5MB in size.
When looking for a software with all of the basic features and functionality one could want from a PDF reader, there is Javelin. At the very least, Javelin will allow you to complete all daily chores easily with its super clean interface and various screen-viewer functions such as full, side by side, continuous, and so on.
It’s a rather lightweight product at 2MB, especially when compared to the likes of Adobe Acrobat Reader DC. In addition to the basics, Javelin can help you view DRM-secured PDF files, which are files that require decryption keys to open.
Aside from Adobe, one of the more well-known names in the world of office productivity software is Nitro Reader. If you’re looking for a free PDF reader that attempts to strike a perfect balance between usability and offered feature, this is it.
You won’t find an overabundance of unnecessary features that you’re not likely to use. Instead, Nitro Reader provides more of a no-nonsense style of PDF reader with its slick interface mimicking the likes of an application straight out of the Microsoft Office suite.
Apart from the basics,Nitro Reader comes with its own digital signature feature, QuickSign, that makes digitally signing documents a breeze. It also allows for the security of individual documents, ensuring that only those who’ve received a digital certificate from you will be able to open the file.
Foxit Reader is both robust and free, creating a double-whammy of sought after potential for most individuals in the market for a PDF reader. Foxit, just like Adobe and Nitro, is a globally recognized name brand in the world of document reader software and is comparatively lighter than both.
The official website for Foxit is well-designed and easy to navigate, offering a solid download experience without the need to push additional bloatware as Adobe tends to do. They’ve also introduced an online ConnectedPDF Document Management System and it doesn’t try to ship some extra bloatware to your PC.
However, it does try to install Foxit PhantomPDF editor’s 14-day trial during the installation process, so take a look at that.
With its 8.0 update, Foxit also introduced its new online ConnectedPDF Document Management System, supplying online security and confidentiality to your PDF documents. This comes in handy while collaborating online and helps to keep your documents organized.
Foxit is an advanced, free PDF reader with all of the necessary features one could ask for. You can also rid yourself of all the frills and bloating that a standard PDF viewer provides by using Foxit’s Text Viewer mode. This will remove all of the complex formatting and allow you to view a document in a more plain Notepad-like display.
This entry onto the list of top PDF readers for 2019 and beyond brings with it a fresh new interface and all of the standard features. Expert PDF Reader is a free PDF reader for Windows that you can download and use to view PDF files.
A list of the features included is the ability to add notes, highlight the text, create a text box, and even creating and managing custom stamps. Unlike some but similar to others on this list, the free software comes with a signature feature included.
There is a premium version, Expert PDF Reader Professional, which had its latest release comes with new features to maintain and preserve PDF files over a lengthy period of time.
On top of this, it features new optimization options when dealing with the size of a file and an OCR function (Optical Character Recognition) to allow easy scanning of images that would otherwise cause complications.
Self-proclaimed as the “world’s smallest desktop PDF reader,” SlimPDF is yet another lightweight reader for the list. With a download size of only 1.43MB, it’s very hard to argue against that claim. This makes it perfect for anyone who has an older model of computer that may have issues running the more complex and heavy PDF readers.
This particular software is one of the best free PDF readers you can use whether your running newer versions of Windows (10, 8.1, 7) or older (XP). Load times are quick and the process is smooth. It may not have the glitz and glam of something like Adobe Acrobat but does offer simplicity and focuses primarily on reading, viewing, and printing your PDF files.
This product doesn’t support many of the more popular keyboard shortcuts you might find in other readers. In order to maintain the self-given crown of being the lightest PDF reader, it had to make sacrifices and can be seen as rather bare-bones. Word by word text highlighting is one of the cut features you might expect as standard, but the reader itself is quite portable and in the end, it just works.
