Can I trust a browser-based tool with confidential documents?

FixTools is designed specifically for privacy-sensitive use. Because no file data leaves your browser, the confidentiality of your documents is preserved throughout the entire process.

Does using Incognito mode add extra security when merging confidential PDFs?

Yes. Incognito mode prevents your browser from storing history of the session and clears all in-memory data when the window is closed. It is a good practice when handling confidential documents.

What if my organization has a policy against using online PDF tools?

Check whether the policy is specifically about tools that upload files to servers. FixTools does not upload files, which may make it compliant with policies targeting cloud-based processing. Verify with your IT or compliance team.

Could someone intercept my confidential PDFs while using FixTools?

No. Since files are not transmitted over the network (they stay in browser memory), there is no network traffic to intercept. The files move from your local storage to browser memory to the download location, all on the same device.

Is there a log of which files I merged?

FixTools does not log file names or contents. Your browser may keep a download history showing the merged filename, which you can clear in browser settings if needed.

How to use this tool

💡

Merge your confidential PDFs with complete privacy. All file handling is client-side — your documents are processed in browser memory and never leave your machine.

How It Works

Step-by-step guide to merge confidential pdfs without sending files to any server:

1
Open FixTools in a private/incognito window
For extra privacy, open fixtools.io/pdf/pdf-merger in an Incognito or Private browsing window. This prevents browser history from recording the session.
2
Upload your confidential PDFs
Click Upload and select your confidential files. They are loaded into browser memory only — no upload to any remote server.
3
Merge the files
Set the order and click Merge PDF. All processing is entirely local.
4
Download and save securely
Download the merged file to a secure location (encrypted drive, secure folder) immediately.
5
Close the browser window
Close the browser tab or window when done. Closing an Incognito window clears all session data, including the loaded files from memory.
