Frequently Asked Questions
How does the PDF merging process remain private?
We leverage the PDF-lib engine directly within your browser. When you merge files, your computer reads the binary data of each document and assembles them into a new structure locally. No fragments of your data are ever uploaded to a server.
Is there a limit on the number of PDFs I can merge?
There is no hard limit on the number of files. However, performance depends on your browser availability and system RAM. For the best experience, we recommend batches of up to 50 files or a total size under 500MB.
Can I merge password-protected (encrypted) PDFs?
For security reasons, our tool cannot merge encrypted files. You must remove the password protection from your documents before they can be processed by our local merger.
