In today's digital age, Office documents such as Word, Excel, and PowerPoint are widely used for creating and sharing various types of content. However, when it comes to sharing these documents, there is an ongoing debate about whether it is better to convert them to PDF within a browser or on a server. While both methods have their merits, there are several compelling reasons why converting Office documents to PDF within a browser may be the superior choice, especially when considering data breach examples that highlight the importance of security.

Why Convert Office to PDF in the Browser?

Instant Accessibility: 

Converting Office documents to PDF within a browser allows users to quickly generate a PDF version without the need to upload the file to a server and wait for the conversion process to complete. On some servers there can be a significant delay if the site is busy, or if very large, or slow, files are ahead in the queue. This instant accessibility is especially advantageous when time is of the essence, enabling users to promptly share or view the PDF without any delays.

Privacy and Security: 

When you convert documents on a server, there is a potential risk of exposing sensitive information to third-party services. Notable data breach incidents, such as the Equifax breach in 2017 and the Nitro breach of 2020, underscore the significance of data protection. For example, Nitro, an online document editing company, suffered a massive breach involving the company's user and document databases as well as 1TB of documents allegedly stolen from the company.

Converting your files within a browser ensures that your document does not leave your device, enhancing privacy and security. By keeping the conversion process local, you have greater control over your data.

Reduced Data Usage: 

Server-based conversions require data to be uploaded, processed, and downloaded back to your device. This can be especially problematic when dealing with large files, consuming both time and data. In parts of the world with poor internet connectivity this could be a major practical issue, as well as potentially costly.

Converting within the browser eliminates the need for excessive data transfers. If the file is on your machine initially, and needs to be there after conversion, why would you send it over the internet if you can avoid doing so?

Offline Accessibility: 

Once the conversion code has been loaded, conversion of a document to PDF can potentially occur even if the browser is offline. This is particularly useful when you're in a location with limited, expensive or no internet connectivity. By avoiding server dependencies, you can continue working regardless of your online status. This puts more control in your hands, since it provides some protection from a Denial-of-Service attack on the server occurring at a time when you need a file converted for an important meeting.

Platform Independence: 

Some people like Windows, others MacOS, some Linux and some Android. The creation of browser-based converters means that everyone can get what they want on the hardware that they want to use. Whether you're using a Windows PC, Mac, tablet, or smartphone, you can access the conversion tool if you have a modern web browser. This level of platform independence is crucial in today's diverse digital landscape.

Resource Efficiency: 

Server-based conversions can put a strain on the hosting infrastructure, leading to slower processing times during peak usage and significant costs for the hosting site. Conversion within a browser reduces the load on external servers, with the user’s machines doing the bulk of the work. Coupled with less data transfer, this contributes to overall resource efficiency and smoother performance.
