FAQ

Merge PDF — Common Questions

Everything you need to know about merging PDF files online.

Is this PDF merger really free?
Yes, 100% free with no hidden charges, no subscriptions, and no account needed. Merge as many PDFs as you like, forever free.
Are my PDF files uploaded to a server?
No. All merging is done in your browser using PDF-lib. Your files are never sent to any server. Everything stays on your device.
How many PDFs can I merge at once?
There is no fixed limit. You can merge as many PDFs as your browser can handle. Very large files (100MB+) may take longer depending on your device.
Will the quality of my PDFs be affected?
No. The tool copies pages directly from each PDF without re-encoding or compressing content. Text, images, and vector graphics are preserved exactly as-is.
Can I merge password-protected PDFs?
No. Password-protected PDFs require the password to access their content. Remove the password protection first, then upload the files to merge.
What does the cover page include?
The optional cover page includes your document title, author name, creation date, total page count, and a list of all the source PDF files that were merged.
