Merge PDF

Add your PDF files, put them in the order you want, and download them joined as one PDF called merged.pdf. You can combine up to 30 files, and every page inside each file keeps its original order. The merge runs in your browser, so your documents are never uploaded.

Your files are processed locally in your browser and are not uploaded to our server.

  4. Click Process PDF to join all the files into one document.
  5. Click Download to save merged.pdf.

When to combine PDF files

  • A job seeker joining a CV, cover letter and certificates into one PDF for an online application.
  • An accountant sending a client one file that holds the invoice, the receipts and the bank statement.
  • A student combining separately scanned chapters or assignment parts before submitting them.
  • A government-service applicant merging an ID copy, a contract and supporting letters for a portal that accepts a single upload.

How this tool works

Add PDFs, drag them into the required order or use the move controls, and create one document. Page order inside every source PDF is preserved.

Example

Put a cover PDF first, followed by two appendices, then download merged.pdf.

Merge PDF: frequently asked questions

Does merging change the page order inside my PDFs?

No. Each file's pages stay in their original order, and the files follow the order shown in the selected-files list. To rearrange single pages, use a page-reordering tool on the merged file.

How many PDFs can I merge at once?

Up to 30. Each PDF can be up to 80 MB, all files together up to 250 MB, and the merged document up to 500 pages, which keeps the browser from running out of memory.

Can I merge password-protected PDFs?

No. A password-protected PDF is rejected with a message, because this browser-only tool does not open encrypted files. Remove the protection in an app where you know the password, then add the file again.

Are my PDFs uploaded to a server when I merge them?

No. The files are read and combined locally in your browser, and only the finished merged.pdf is saved to your device. Your internet connection is needed only to load the page and its PDF engine.
