What are the Downsides of Using Online Tools?

When it comes to the usage of online tools or, more specifically, free online tools, there are several reasons why you shouldn't be using them. From the risk of your data being stolen to being limited to the number of files, you can convert to PDF, the disadvantages greatly outweigh the perks you might attain.

Here are some of the other downsides you might face while using online tools:

Lack of Privacy

By using free online tools, the biggest downside, without a doubt, is the lack of privacy. Considering how these platforms don't always have a private server to back up your data, the chance of your data being accessed by other users is incredibly high. Plus, your data is only sometimes backed up, meaning you can't access it later on if required.

Lesser Features

Free platforms allow for a minimalistic number of services and only allow you to use the basic features. For instance, you may be able to convert your JPG to PDF, but you won't be allowed to make further changes, such as adding text or converting a selected portion of your JPG to PDF.

Limited to a Certain Number of Files

One of the biggest problems people face with online tools is that they only allow you to convert a selected number of photos to PDF. This way, you either have to wait for the next day to upload more files or convert specific files separately. This limitation becomes problematic, especially if you're looking to generate a larger report for a company or project.

Not Being Able to Edit Freely

Lastly, online tools don't allow PDFs to be edited freely. For this reason, you can convert your files to PDF, but you won't be able to edit them any further if needed.

Why Should You Use UPDF for Image-to-PDF Conversion

Using paid tools such as UPDF has its fair share of perks. For one, you can always ensure that your data remains safe. To edit or convert pictures to PDF, UPDF doesn't just get the job done; it goes above and beyond. It allows you to organize your files to be used later on and enables you to edit them.

Overall, you know how to convert images to PDF. It's easy to see what benefits you can have compared paid tools to using free tools. With free tools, you may risk your data and get limitations in converting images to PDFs. But a paid photo-to-PDF converter tool such as UPDF will help you out!
