How to Merge PDF Files for Free (No Software Needed)

Combine multiple PDFs in your browser: upload, reorder, download — no install or account required.

Need one PDF from several reports, scans, or invoices? Merging online avoids installing Acrobat or fighting printer dialogs. PdfPeaks lets you upload, reorder, and download a combined file in your browser.

Step 1 — Gather your PDFs

Use clear filenames before upload. If any file is password-protected, unlock it first with the password you already have.

Step 2 — Merge and reorder

Open Merge PDF, add files, and drag them into the final page order. Use Organize PDF afterward if you need to delete or shuffle pages inside the combined document.

Step 3 — Compress the result

Merged files can be large. Run Compress PDF before emailing. Read how to reduce PDF file size for preset tips.

Images into one PDF

Starting from photos? Convert with JPG to PDF or Image to PDF, then merge with your other PDFs.

Protect the final packet

Shipping contracts or HR packets? Add password protection after merging. For encryption basics, see unlocking password-protected PDFs safely.
