Merge PDF

Merge PDF

Combine multiple PDF files into one PDF when a form or portal expects a single document. The merge happens in your browser and the result downloads locally as merged.pdf.

When to use it

  • Combine a form, ID scan, and supporting document into one PDF.
  • Keep files in the same order you add them.
  • Create a single PDF package before submitting a document portal.
  • Stay within a browser-only workflow with no account or cloud storage.

How it works

Select two or more PDFs, review the local file list, remove anything you do not want, and create merged.pdf. The MVP uses pdf-lib to copy pages from each selected PDF into a new PDF in the order shown on screen.

The current limit is 20 PDFs and 100 MB total selected size. Encrypted or damaged PDFs may fail because the browser cannot read their pages.

Privacy principles

  • No upload.
  • No account is required.
  • No cloud storage is used.
  • No file history is kept by the app.
  • The result downloads locally through a temporary Blob URL.
  • Selected PDF contents are not intentionally sent to analytics tools by the app.

FAQ

Can I merge PDF files without an account?

Are my PDFs sent to a server?
No. Selected PDFs are read by your browser and combined locally with pdf-lib. The files are not sent to a server.
How many PDFs can I combine?
The MVP accepts up to 20 PDFs with a combined selected size of up to 100 MB.
What if a PDF is encrypted or damaged?
Encrypted or damaged PDFs may fail to merge. The tool shows an error and leaves your selected files local to the browser.
