Frequently Asked Questions about Merging PDFs
Is it safe to combine confidential PDFs with this tool?
Yes, it is the safest method available. Since all files are processed locally on your computer, your confidential documents are never uploaded to a server. This guarantees your privacy when you join PDF files.
Is there a limit to how many PDF files I can merge at once?
Our tool is designed to handle a large number of files. While we recommend up to 20 files for optimal performance, the main limitation is your browser's memory. For most users, merging many files is fast and efficient.
Will merging PDFs reduce the quality of my documents?
No, our PDF merger combines documents without re-compressing or altering the quality of your original files. The content, formatting, and quality of each page will be preserved in the final merged document.
Can I reorder the PDF files before merging them?
Absolutely. After selecting your files, you can easily drag and drop them into the correct sequence. This ensures your final document is perfectly organized before you combine the PDFs.
