How this PDF merger works

Select the PDF files you want to combine. Each appears as a row showing its name, file size, and page count. Use the arrow buttons to set the order, then press Merge. The tool copies every page from each file into a new document in your chosen order and gives you a single PDF to download. Nothing is uploaded to a server.

When would you use this?

How does this compare to other PDF mergers?

Smallpdf, ILovePDF, and Adobe Acrobat online upload your files to their servers and have free tier limits — typically 2 tasks per hour. Adobe Acrobat online requires an account. This tool merges entirely in your browser with no limits and no uploads — particularly important when your PDFs contain sensitive financial, legal, or personal information.

Does merging affect quality or compress the files?

No. Pages are copied as-is, preserving all content, formatting, and resolution. If you need a smaller file afterward, use the Shrink PDF tool on the merged result.

Is there a limit on how many files I can merge?

No fixed limit. Very large PDFs may take longer depending on your device's memory, but there is no artificial cap.

What if my PDF is password protected?

Password-protected PDFs cannot be read by this tool. Remove the password first using a PDF editor, then merge the unlocked files here.

Do you store or see my documents?

No. The merge happens entirely in your browser. Your PDF files are never uploaded anywhere.

Can I merge scanned PDFs?

Yes — scanned pages and most form fields are preserved exactly when copied into the merged document.
