Frequently Asked Questions
Is there a limit on how many PDF files I can merge together?
There is no artificial limit on the number of files. You can combine dozens of documents as long as your computer or device has enough browser memory to process them.
Will merging documents alter the formatting, page orientation, or fonts?
No. FileVance uses pdf-lib to copy native PDF page dictionaries without re-rendering, so all original vector graphics, fonts, margins, and landscape/portrait orientations are preserved.
Can I add more PDF files after I have already uploaded the first few?
Yes. You can use the Add More Files button at any time to include additional documents and reorder them within the queue before generating the final merged file.
Are my confidential contracts or tax PDFs uploaded to a server?
No. All PDF merging takes place entirely within your browser memory. Your documents are never uploaded to any cloud storage or external server.
Can I merge password-protected PDF files?
If a PDF has an opening password restriction, you should first remove the password using the PDF Security tool before merging it with other documents.
