Why use Forge Files?

What you can merge

Combine any number of PDF files into a single document: reports and their appendices, scanned pages, invoices, or chapters exported separately. There is no two-file free cap and no page limit beyond your upload size. Drag the files into the order you want before merging, so the final PDF reads top-to-bottom exactly as intended.

Common uses

Merge vs. split, organize, and compress

Merging only joins files. If you also need to drop or reorder pages, Organize PDF gives you page-level control; to pull pages out instead, use Split PDF. Merged a lot of image-heavy files? Run the result through Compress PDF once at the end to keep the size down.

Is the Merge PDF tool private?

Yes. Your file is uploaded over encrypted HTTPS, processed, handed back, and then deleted — the upload goes the moment the Merge PDF operation finishes and the result the instant you download it, with an hourly sweeper as a backstop. Unlike closed tools that just claim they don't keep your files, Forge Files's code is fully open source, so you can verify exactly how the Merge PDF tool handles your data — or self-host it. No account, no watermark, no upsell. See our privacy details for the full picture.

Frequently asked questions

How many PDFs can I merge at once?

As many as you like in a single pass: select them all in the upload area. There's no artificial two-file limit.

Can I choose the order of the merged pages?

Yes, the files are combined in the order you select them, so arrange them the way you want the final document to read.

Can I merge a password-protected PDF?

Remove the password first with the free Unlock PDF tool, then merge the unlocked copy with your other files.
