Now that you know all the features of BIGPDF, let’s find out whether it is also secure and free to use!
Part 2. Is 11zon BIGPDF Free and Safe?
BIGPDF is a free online tool to manage PDFs without any cost. Its features have no usage limits or hidden fees, and it doesn’t add watermarks to your files.
But is it as secure as it is free?
11zon claims they automatically delete all uploaded files from their servers after two hours. However, they still store your files on their system during this time. This makes them vulnerable, especially if they contain personal or sensitive information.
Part 3. Why Not Recommend to Use 11zon BIGPDF?
When choosing a reliable PDF solution, you want to ensure that the tool matches your needs and provides a seamless workflow. In our testing, BIGPDF failed to meet these basic requirements.
Here are the reasons we do not suggest using it.
1. Lacks Key Features You Need
If you work with PDFs frequently, you may need to add or edit the PDF text, images, and links. Sometimes, you just want to open and read it or annotate it with highlights and underlines. Unfortunately, BIGPDF doesn’t offer these essential features.
2. Annoying ads
Another downside is the random ads. They appear on the tools page and as popups when processing files. It gets annoying because they keep interrupting your workflow.

3. False Propaganda
BIGPDF doesn’t allow batch conversion for many file type conversion, including Word to PDF, PPT to PDF, Excel to PDF, TXT to PDF, or CHM to PDF. The frustrating part is that the website says it does, which raises concerns about the platform’s reliability.

4. Slow Processing
The platform claims to be fast. However, when tested, the processing speed for uploading multiple PDFs was very slow, even for documents of smaller size.
