Merging PDFs combines several files into one clean document in the order you choose. It's one of the most common document tasks: stitching a signed contract onto its cover letter, combining scanned receipts for an expense report, or assembling chapters into a single deliverable. Instead of sending five attachments, you send one.

File Converts merges your files in your browser — they're never uploaded to a server. That keeps confidential paperwork private, removes any upload wait, and means there's no cap on how many files you combine or how large they are. Just add your PDFs, drag them into the right order, and download the combined file instantly.

Because the merge happens on your device, it's also fast: there's no round-trip to a server and back, so even a large stack of documents combines in moments. Page order is preserved exactly as you arrange it, and the original files are left untouched.

Merging pairs naturally with the rest of the PDF toolkit. Split a PDF first to pull out just the pages you need, then merge them with another document; add page numbers to the combined file; or run Compress PDF afterward if the merged result is large. Everything runs locally, so your documents never leave your computer at any step.

Frequently asked questions

Yes. You can merge a large number of PDFs in one go — each file can be up to 50 MB. Everything is combined in your browser, so there is no upload queue to wait through.

No. The merge runs entirely on your device. This is the practical reason to use it for sensitive material — contracts, invoices, signed forms and scans stay with you.

No. Merging copies the original pages across untouched; it does not re-compress or re-render them. If the merged file is too large to email, run it through Compress PDF afterwards.
