Are my files uploaded to a server?

No. TrulyFreePDF runs entirely in your browser - your file is opened and processed on your own device and is never uploaded, stored, or shared.

How many PDFs can I merge?

There is no fixed limit - merge as many files as your device memory allows.

Is this really free, or free "until you hit a limit"?

Really free. Unlike most "free" PDF sites there is no task-per-day cap, no locked Pro features, no watermark stamped on your file, and no payment step before download. Every tool is the full tool.

Merge PDFs, free in your browser

You can merge PDFs into one file here in your browser: add two or more PDFs, drag them into the order you want, then download the combined document. The files never leave your device - no upload, no account, no watermark, and no cap on how many you combine.

How to merge PDFs

Add two or more PDF files.
Drag them into the order you want with the arrow buttons.
Click Merge and download the combined PDF.

Limits & good to know

There is no fixed file-count or size cap; the practical limit is your device memory, because nothing is sent to a server.
Pages are copied as-is - merging never re-compresses or degrades a page.
Interactive form fields and bookmarks from the source files may be flattened in the combined document.
Password-protected PDFs need to be unlocked before they can be merged.
