Frequently Asked Questions
How many PDF files can I merge at once?
There is no limit. You can merge as many PDF files as you need. Simply keep adding files and reorder them before clicking Merge.
Can I reorder the files before merging?
Yes. After adding your files, drag and drop them into the order you want. The merged PDF will follow the order shown in the list.
Will the merged PDF lose any quality or formatting?
No. The merge is done by copying pages directly using pdf-lib, so fonts, images, and formatting are preserved exactly as in the originals.
Can I merge password-protected PDFs?
No. Encrypted or password-protected PDFs cannot be processed. Remove the password protection first using a PDF reader before merging.
Are my files uploaded to a server?
Never. All merging happens entirely inside your browser using JavaScript. Your files are never sent to any server and are not stored anywhere.
