TopToolsAiCombine multiple PDF files into a single document, in the order you choose — no software installation needed. Combine a cover letter PDF, a resume PDF and a certificate PDF into one single file in that exact order — many job application portals only accept a single upload, not multiple separate attachments.

Frequently asked questions
Is there a limit on how many PDFs I can merge?
It's built to handle a reasonable batch of files — for very large numbers of files, merge them in smaller groups first.
Can I control the order of the merged pages?
Yes, arrange the files in the order you want before merging — that order carries into the final PDF.
Are my files uploaded to a server?
No — merging happens directly in your browser, so your PDFs never leave your device.
Does it work with password-protected PDFs?
No — remove the password protection from each file first, since the tool can't open locked PDFs.
