Part 3. Limitations and Drawbacks of Joining PDF Files into One Online

While joining PDFs online is simple and hassle-free, there are a few limitations that you should be aware of before making a final choice. Here, we have mapped out some limitations and disadvantages of joining PDF files into one online.

  • Security

When joining PDFs online, you must upload the file to the interface, and the whole processing is done on their cloud storage. While the process saves space on your system, it directly affects the privacy of your PDF file, especially if it contains something confidential. Almost all online tools assure to delete your file after processing, but there's no proof to support their claim, making such options a bit risky.

  • Network stability

There's no second thought that Online PDF joiners require a stable and robust internet connection to combine PDFs. You cannot use them if you experience poor or unstable data networks, which is why a desktop application is preferred.

  • File size limitation

The next major drawback of using online PDF joiners is that they don't support large file sizes, which can be frustrating if you wish to merge large PDF files. The file size limit usually supported by online tools is around 50 to 100MB, making them non-suitable for users who want to merge large files.

  • Quality

No matter how secure and advanced a PDF joiner is, it's of no use if it does not deliver quality output. These tools have different algorithms, which sometimes reduce the quality of the merged document, leaving the user disappointed.

Since online tools are packed with lots of safety concerns and other drawbacks, it's always good to keep a desktop application handy and combine PDF files quickly and safely.
