Frequently Asked Questions
How many PDF files can I merge at once?
You can merge multiple PDF files in a single operation. There is no strict limit on the number of files, though very large files may take longer to process. The maximum file size per file is 100MB.
Will merging PDFs reduce the quality of my documents?
No. PDF merging combines the files at the document level without re-encoding any content. Images, text, fonts and formatting in each PDF are all preserved at their original quality in the merged output.
Can I merge password-protected PDFs?
Password-protected PDFs cannot be merged without first removing the password protection. You would need to unlock the PDF first, then merge the unlocked files.
Are my PDF files kept private?
Your PDF files are sent to our secure conversion service for processing and are immediately deleted after your download is complete. We do not store, read or share your documents.
Can I merge PDFs on my phone or tablet?
Yes. Our PDF merger works on any device with a modern browser — iPhone, Android, iPad or any tablet. No app download is needed. Simply open the page in your mobile browser and follow the same steps.
