We often work with many file formats when sharing and storing documents. Two of the most common are PDF and DOCX. Both formats have their own features and uses, but what sets them apart and when should you choose one over the other? To answer this, we will look at the main differences between PDF and DOCX files. Whether you are a student, a professional, or a casual user, understanding the key differences between PDF and DOCX files is essential to effectively share, store, and manage your documents.
What is a PDF file?
PDF stands for Portable Document Format. It is the most common format for sending documents, especially ones that should not be changed later. The PDF format was developed by Adobe. It can display documents, text formatting, and images in a way that is independent of application software, hardware, and operating systems.
What is a DOCX file?
A file with the DOCX extension is a Microsoft Word Open XML Format Document file. DOCX files are stored in the Open XML format, which was introduced with Microsoft Word 2007 and is used by default in all later versions of MS Word. Earlier versions of Word use the DOC file extension. DOCX is one of the most popular formats for working with office documents.
The main differences between PDF and DOCX files
Editing capability
Editing capability is one of the main differences between PDF and DOCX. In general, PDF files are regarded as read-only, which means that once they have been created, they usually cannot be edited or modified. As a result, PDFs are ideal for sharing or printing documents since they always maintain their original formatting and appearance.
On the other hand, DOCX files are editable and can be modified using a word processor such as Microsoft Word. This makes them useful for creating and editing documents that will be continuously revised and updated. However, this also means that DOCX files may not always maintain their original formatting when opened on different devices or in different software.
DOCX provides document creation and editing with a wide range of tools in an efficient and standardized way. You can format and align text, insert complex images, equations, tables, charts, headers/footers, hyperlinks, comments, references, watermarks, and more. It is also easier to share and collaborate on DOCX documents compared to older file formats like DOC.
PDF is a better choice for documents that need to maintain a specific layout, such as contracts or forms, while DOCX is better for documents that need to be edited and formatted, such as reports or essays.
Compatibility
Another difference between PDF and DOCX is their level of compatibility. Almost every device, including PCs, smartphones, and tablets, can open and view PDF files. This makes them an excellent choice for documents that need to be shared with many people, as they are very likely to be able to open and view the file.
DOCX files, on the other hand, are primarily associated with Microsoft Word. While they can be opened and viewed on other devices, they may not retain their original formatting and may require the use of a compatible word processor in order to be edited. Apart from MS Word, other word processors, such as the open-source office suites LibreOffice Writer or OpenOffice can be used for editing .docx files. Google Docs or Microsoft Word Online can also be used to make necessary changes in Word documents.
File security
Both formats come with security tools that protect content and restrict access to specific users. PDF and DOCX formats initially enable the following security features: password protection, digital signatures, watermarks, and limitations on copying and printing.
However, since DOCX also allows for co-editing, some phases of its life cycle call for additional security measures. To safeguard data from alteration or unauthorized access, users can be granted advanced sharing permissions, which vary depending on the processing software.
Security vulnerabilities can be found in any file type if they are not properly protected. In general, DOCX files are considered to be more susceptible to tampering, since they are editable and more vulnerable to being modified without authorization.
Image & graphic handling
PDF and DOCX files can handle images and graphics, but they are better suited for different purposes.
For images and graphics in documents intended for printing or electronic distribution, PDF files are a better choice. Since users cannot easily edit the information that has been converted to a PDF (PDFs are intended to be read-only documents), they are ideal for documents like brochures, flyers, and reports that need to be distributed widely. The images and graphics are embedded into the PDF, so they will display correctly and maintain their quality when viewed on different devices.
DOCX files, on the other hand, are better for handling images and graphics when the document is intended for editing and collaboration. Since DOCX files are editable, they are preferable for creating documents that will be frequently updated and shared among a team, such as reports, proposals, and presentations.
File size
In general, PDF files tend to be smaller in size than DOCX files since they are optimized for viewing and printing rather than editing. You can choose to compress the PDF to reduce the file size. This can be especially useful if you need to share the PDF file online or by email, when file size may be a concern.
DOCX files are designed for editing and may contain more detailed information and formatting, which can make them larger in size. Note that you can always convert a DOCX file to a PDF file. This can often result in a smaller file size due to the optimization and compression of the PDF format.
Once you convert a document to a PDF file, you cannot convert it back reliably unless you use special software tools with the OCR function. One such tool is PDF2Go's PDF to Word converter.
Conclusion
In summary, PDF and DOCX are both useful file formats for storing and sharing electronic documents. PDFs are better for documents that need to keep a fixed layout and work on many devices, while DOCX is better for documents that need to be edited and formatted. PDFs are generally more secure and better at preserving image quality, while DOCX files support co-editing and can be easily modified.
It is important to note that you can easily convert both formats using a web-based service such as PDF2Go.
