Why client-side PDF processing

Your PDF files are merged in the browser—they are not uploaded to a server. This suits sensitive contracts, medical forms, and personal documents.

Common use cases

  • Combine scanned documents
  • Merge contract appendices
  • Join report sections

FAQ

Is there a file size limit?

Large files depend on browser memory; keep batches reasonable.

Can I reorder files?

Yes. Reorder the file list before merging; page order follows file order.

Are PDFs uploaded to a server?

No. Merging runs locally in your browser.

How many PDFs can I merge?

Up to 20 files per batch in the browser UI.
