FAQ — Merge PDF Files Online

1. How many PDF files can I merge at once?

You can merge as many PDF files as you need in a single operation. The only requirements are a minimum of 2 files and a maximum size of 10MB per file. There is no limit on the total number of pages in the final merged document.

2. Will the quality of my PDF be affected when merging?

No. Merging PDF files with this tool does not compress, resize, or alter the content of your original documents. All pages are imported and combined at their original resolution and dimensions, preserving text, images, and layout exactly as they appear in the source files.

3. Can I merge scanned PDF files?

Yes. This PDF merger works with all types of PDF files, including scanned documents, image-based PDFs, digitally created files, and password-free PDFs. The tool imports each page as-is, regardless of how the PDF was originally created.

4. Can I change the order of pages before merging?

Yes. After uploading your files, you can drag and drop them in the list to set the exact order you want. The pages will appear in the merged PDF in the same sequence as the files in your list — from top to bottom.

5. Is this PDF merger completely free?

Yes. Merging PDF files on this tool is 100% free with no hidden costs, no daily usage limits, and no account required. Simply upload your files and merge as many times as needed.

6. How are my files handled after merging?

Your privacy is a priority. All uploaded source files are deleted immediately after the merge is complete. The merged PDF file is also automatically deleted from our servers after 24 hours. Your documents are never shared with or sold to any third party.

7. What should I do if my PDF files are password-protected?

This tool does not support password-protected or encrypted PDF files. You will need to remove the password protection from your PDFs before uploading them for merging. Most PDF readers, including Adobe Acrobat Reader, allow you to unlock a PDF if you know the correct password.

Note: This free online PDF merger is designed for personal and professional use — combining contracts, reports, invoices, presentations, or any standard PDF documents. Files are processed server-side only for the duration of the merge and automatically deleted afterward to protect your privacy.
