While we are heading towards a more digitized world, safety and security are becoming a big concern. Almost all software are now developed keeping user privacy in mind. Although, there are some who are taking advantage of this ever digitizing world. Stealing of data and other private information has become a common issue.

When it comes to file safety, people generally show more faith in offline converters than online converters because offline converters are not connected to the internet and therefore cannot leak your data to the internet world.

The evergoing debate on the safety of online converters has now reached its peak. With hundreds of online converters available in the market, users are overwhelmed with the choices they have. However, not all of these online converters are as safe as they claim to be. Hence, one must do the appropriate research before using such converters. Here, we have done that research for you. In this blog, we will be talking about one such converter called the Sejda PDF. Let’s have a look at what Sejda PDF is all about and its safety. So let’s get started without further ado.

Therefore, while Sejda may be all about safety, it cannot stop hackers to exploit your data. Let’s first have a look at how to convert PDF to JPG using Sejda PDF converter before looking at how hackers might be able to access your data.

Now that we know how to convert our PDF to JPG using Sejda, let’s look at how hackers might be able to exploit it. While converting or processing files in Sejda, a network call is being made to store files on the server.

Files server is connected to the internet and configured that the users are not able to access the files through the local network. Write the means file is saved to their server, and data can get compromised if their server is hacked. Therefore, if some hacker manages to take control of the server and compromise it, your entire data can be leaked in a breach.

A probable solution to this is to use serverless converters. A serverless converter is one that converts your files using a browser and without depending on a server. One such PDF editor and converter is Safepdfkit.

Safepdfkit is a risk-free converter as no data about the PDF is transferred to the server. The file that you have shared with Safepdfkit will not transfer any of your data to the server. Also, it is an easy-to-use and secure service. Only the necessary information is collected for achieving a safe experience and customizing your needs. The SSL encryption and the serverless interaction provides the guarantee to secure your data 100%. This whole functionality is implemented using JS libraries on the browser. Just a few years ago, such converters would not have been possible but thanks to advancements in technology, it now is.

Safepdfkit makes use of various advanced JavaScript libraries to achieve this. Libraries are used to create a web page using UI components, math functions, language utilities, etc. It provides a lot of functionalities. One of the essential JavaScript libraries that Safepdfkit uses is:

PDF-LIB: It is a JavaScript library specially designed to efficiently and safely handle PDF files. It allows users to create PDF documents from scratch, or modify existing PDF documents. Written in TypeScript and compiled to pure JavaScript with no native dependencies, it works smooth as butter.

Not only can PDF-LIB create and modify PDFs but also can add, insert, and remove pages. It can split a single PDF into separate ones or merge multiple PDFs into a single document. What’s so special about this library is that it works in any JavaScript runtime, including browsers, Node, Deno, and even React Native. The ability to work in browsers removes the dependency for servers ensuring safe serverless conversions. All in all, it is a very powerful library and is aptly used by Safepdfkit.

In conclusion, serverless converters are anytime a better choice over server-dependent converters no matter how safe the latter claims to be. We hope this blog somewhere cleared your queries regarding the safety of such online converters.
