How to merge PDF files
- Open the PDF tools and choose Merge PDFs.
- Select two or more PDFs in the upload area (multi-select is enabled).
- Click Merge and download the single combined PDF. Every uploaded file is deleted automatically.
Why use Forge Files?
- Unlimited combining: merge as many PDFs as you need: no two-file free cap.
- Verifiably private: your files are deleted right after download, and the code is open source so you can confirm it.
- Free, no signup: no account, no watermark stamped across your pages.
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
- Bundling a cover letter, CV, and portfolio into one file to upload.
- Joining separately scanned pages back into one document.
- Combining monthly statements or invoices for a single submission.
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.
