PDF Merger

Combine multiple PDF files into one document

Pages are merged in your browser, your files are never uploaded or stored anywhere.

About this tool

Whether you're combining invoices, reports, or scanned pages, a PDF merger saves you from printing and rescanning or juggling multiple attachments. This tool stitches your PDFs together in seconds, in exactly the order you choose.

Everything runs locally in your browser: select your files, arrange them with the up and down arrows, and click merge. The result downloads as a single merged.pdf with all pages preserved in their original quality.

  1. 1Click the file picker and choose two or more PDF files.
  2. 2Use the up/down arrows to set the order the files will appear in.
  3. 3Click “Merge PDFs” and wait for the progress bar to finish.
  4. 4Your combined PDF (merged.pdf) downloads automatically.

Good to know

Because no files are uploaded, this is a safe option for sensitive documents like contracts or tax paperwork. Files up to 50MB each are supported, and corrupted or password-protected PDFs are flagged with a clear message instead of silently failing.

Frequently asked questions

No. Merging happens entirely in your browser using JavaScript, your files never leave your device, are never uploaded to a server, and nothing is stored.
