Everything you need in a free PDF merger

Combine multiple PDFs

Merge two or more PDF files into a single document while keeping original pages, text, and layout intact.

Reorder before you merge

Drag in files, then move them up or down so the final PDF follows the exact sequence you need.

100% browser-based

Merging runs with pdf-lib in your browser. Your documents stay on your device — nothing is uploaded to Focera.

Fast drag & drop workflow

Drop several PDFs at once (up to 20 files), adjust order, merge, and download in a few clicks.

How It Works

Combining PDFs should be quick and private. Focera keeps the whole flow on one page — upload, reorder, merge, and download without an account or desktop installer.

  1. Upload your PDFs. Drag and drop two or more files (up to 25 MB each, 20 files total), or click the zone to browse from your device.
  2. Set the merge order. Use the up and down controls to arrange files. Remove any you do not want included.
  3. Merge and download. Click Merge PDFs. Pages are copied into one document locally, and the combined file downloads automatically.

Jump back to the PDF merger anytime to combine another set of files.

Popular Use Cases

  • Compile reports — Join chapter PDFs, cover pages, and appendices into one shareable file.
  • Bundle contracts and forms — Combine signed pages, addenda, and supporting docs before sending.
  • Assemble study packs — Merge lecture slides, worksheets, and notes into a single PDF.
  • Prepare application packets — Stack resumes, portfolios, and certificates in a fixed order.

Private by Design

Your PDFs are read and merged entirely in your browser. Focera does not receive the files, store pages, or run merging on a remote server. When you leave the page, nothing remains on our infrastructure.

FAQ

Is this PDF merger free?

Yes. Merge unlimited PDFs with no account, subscription, or daily limit.

Are my PDFs uploaded to a server?

No. Merging runs entirely in your browser with pdf-lib. Your files stay on your device.

Can I change the order of PDFs before merging?

Yes. After uploading, use the up and down controls to set the exact merge order, or remove files you do not want included.

How many PDFs can I merge at once?

You can merge up to 20 PDF files in one go. Each file can be up to 25 MB, with a combined size limit of 100 MB.

Does merging keep text and layout?

Yes. Pages are copied as real PDF pages — text, vector graphics, and layout are preserved. This is not a print-to-image merge.

Can I merge password-protected PDFs?

Not yet. Remove the password from protected files first, then upload them to merge.

Do I need to install software?

No. Open the page in a modern browser, drop your PDFs, and merge immediately.
