What this tool does

Combines two or more PDF files into a single document, in whatever order you choose. Useful for stitching together scanned pages, combining a cover letter with a resume, or assembling a set of reports into one file before sending it.

Everything happens in your browser — your files are never uploaded anywhere.

How to use this tool

1Click the upload area (or drag and drop) to add two or more PDF files.
2Reorder them by dragging a row, or with the up/down arrows — the final PDF follows this order.
3Click Merge, then download the combined file.

Good to know

  • Password-protected or corrupted PDFs can't be read by this tool — remove the password first
  • Page order and orientation from each source file are preserved exactly
  • There's no practical limit on how many files you can combine, though very large files take longer to process

FAQ

Are my files uploaded to a server?
No. The merge happens entirely in your browser using JavaScript — your PDFs never leave your device.
Is there a file size or page count limit?
No hard limit is enforced, but very large PDFs (hundreds of MB) may be slow or use a lot of memory since everything runs in your browser tab.
Can I merge a password-protected PDF?
Not directly — remove the password/encryption from the file first using your PDF reader, then merge it here.
