Frequently Asked Questions
Does AISEO's Merge PDF tool store my files online?
No, your files are never stored online. The entire merging process happens directly inside your web browser, ensuring that your documents remain private and fully under your control. Once the merge is complete, your uploaded files are automatically deleted from the system. Nothing is saved, nothing is shared, and nothing is sent to external servers.
Can I merge PDFs offline using this tool?
No, AISEO's Merge PDF tool requires an internet connection since it operates through your browser. However, it's designed to be lightweight, so it works even with slower connections without lag.
Will the merged file open on any device?
Yes. The final file is a standard PDF that opens smoothly on any device or operating system. You can share it via email, upload it to cloud storage, or view it using any PDF reader without compatibility issues.
Is the tool safe for confidential or private documents?
Absolutely. AISEO's Merge PDF tool uses a privacy-first design. Since all processing happens in your browser, your documents never leave your device. Once the process is finished, the files are automatically deleted. You can merge personal or professional files with complete peace of mind.
Do I need to create an account to download my merged file?
No. Once your merged PDF is ready, you can download it immediately without signing up. The download link appears instantly, and the file saves directly to your device. It's that simple.
What happens if my internet connection drops during merging?
If your connection is interrupted, the process will stop safely without losing your data. Once you reconnect, simply reload the page, re-upload your files, and merge again. The tool will pick up right where you left off.
How long does it take to merge PDFs?
In most cases, the process takes only a few seconds. Even larger files with hundreds of pages merge quickly because the tool is optimized for performance. You won't have to wait through long loading screens or complicated steps.
Is there a limit to file size?
There is a size limit for free users, but it's generous enough for most regular tasks. For larger or more complex files, upgrading to the premium version gives you extended capacity and faster performance.
