Best PDF reader for Windows – Top 5
A good PDF reader for Windows should make your common PDF tasks easier, not simply give you more buttons. These are the PDF readers that I see fit for everyday use.
1. Adobe Acrobat Reader
You must have heard about it at least once. The Adobe Acrobat Reader is undoubtedly one of the most popular PDF managing tools in the world. It is a free application that allows users to view and manage PDF documents with additional features, such as commenting, highlighting, etc.
The feature I liked most about Acrobat Reader is the quality of the reading, which is always consistent in terms of appearance, and the ease of use of the application is also worth mentioning. The search, navigation, and commenting functions are also reliable and practical to use.
Pros
- Trusted and widely used PDF application.
- Reliable PDF viewing and rendering.
- Strong annotation and commenting tools.
- Supports PDF form filling.
- Add signatures without paying.
- Regular security updates from Adobe.
Cons
- Advanced PDF editing requires a paid Acrobat plan.
- Heavier than lightweight alternatives such as Sumatra PDF.
2. Sumatra PDF
If your requirement is simple, open a PDF and start reading without waiting around. Then, Sumatra PDF reader is what you want. There are multiple reasons to call it the best PDF reader for Windows. It is a small, free, open-source Windows application that allows you a simple PDF reading experience without many distractions.
During our comparison, Sumatra PDF stood out for its simple interface and low resource usage. It opens documents quickly and does not surround basic reading with a collection of features you may never use. It is also portable, so you can run it from a USB drive without installing it.
Pros
- Very fast startup and document loading.
- Lightweight and uses relatively little memory.
- Completely free and open source.
- Portable version is available.
- Supports several formats besides PDF.
- Simple interface that is easy to understand.
Cons
- Not designed for advanced PDF editing.
- Fewer document-management features than full-featured PDF applications.
3. PDFgear
PDFgear is the most interesting option on this list if you want more than a PDF viewer without spending money. I found it good for reading, annotation, direct text editing, page management, and conversion. I also like the PDFgear AI chatbot that they offer.
When comparing the applications, the biggest advantage of PDFgear is the number of options it gives to users in the free desktop version. You can edit existing PDF text, work with images, organize pages, annotate documents, and more.
Pros
- Free desktop PDF reader and editor.
- Can edit existing PDF text.
- Supports annotations, signatures, and page management.
- Includes OCR features.
- AI-assisted reading and document interaction.
- Does not add watermarks.
Cons
- The large feature set can take some time to learn.
- Users who only need a fast viewer may find it more than they need.
4. PDF-XChange Editor
Another good PDF reader for Windows I found during the research is the PDF-XChange Editor. The free version includes a surprisingly broad collection of viewing, annotation, OCR, signing, and document tools.
One interesting thing that the PDF-XChange Editor offers is control. You can customize the interface, work with tabs, search documents, use thumbnails, create annotations, add signatures, and use OCR. The majority of these features are available for free.
Pros
- Large set of free PDF tools.
- Strong annotation and markup capabilities.
- Extensive customization options.
- Tabbed interface and multiple document views.
- Supports digital signatures and many document-management functions.
- Regular updates and software improvement.
Cons
- The interface can feel crowded for first-time users.
- Some advanced functions require a license.
5. Foxit PDF Reader
In the best PDF reader for Windows list, I placed Foxit PDF Reader last, but in no way is this tool inferior to the above four. This tool supports viewing, printing, form filling, annotation, commenting, and signing workflows. It is more feature-rich than a minimalist reader such as Sumatra PDF and charges nothing for it.
Pros
- Full-featured PDF viewing and printing.
- Good annotation and commenting tools.
- Supports PDF form filling.
- Useful for collaborative document review.
- Available for Windows and supports other platforms as well.
- Offers a free Reader alongside its paid editing products.
Cons
- Some advanced editing and e-signature functions are paid.
- The interface can feel more feature-heavy than necessary if you only want to read PDFs.
What to do if you cannot open a PDF file?
A PDF reader can open, display, annotate, and sometimes edit a document, but that does not mean it can open a damaged PDF file too.
In that situation, repeatedly trying different readers may not solve the underlying issue. You need a PDF repair tool that can analyze the damaged file and rebuild its accessible content.
The Kernel for PDF Repair is designed for this purpose. It can repair corrupted or damaged PDFs and recover content such as text, images, hyperlinks, graphics, watermarks, and digital signatures. It also supports batch processing and can save the repaired document as a new PDF.
The tool is available as a trial, which lets you add and repair corrupted PDF files for free. However, accessing the recovered output file requires the full version.
What is the best PDF reader for you?
Overall, the best PDF reader for Windows you can choose depends mostly on your requirements. A lightweight reader can be better than a feature-heavy application when all you need is reading. On the other hand, if you regularly edit, annotate, sign, or manage PDF pages, choosing a more capable application can save you time.
However, if you are getting PDF file errors when opening them in a reader, then installing another reading tool may not solve the problem. In such cases, a dedicated PDF repair tool is the appropriate solution.
