PDF to ZIP: Bundle PDFs into One Archive

Put PDFs into a ZIP when a form or email wants one file, not twenty: every PDF goes into a single archive, with the names you gave them. It’s built in your browser, so nothing is uploaded.

Where is this PDF going?

Settings appear once you add a PDF.

Number the files in the order above 01-invoice.pdf, 02-receipt.pdf… so they stay in order when unzipped.

Done on your device No upload, no queue, no sign-up.

How to put PDFs into a ZIP online

Your PDFs go into this browser tab, are packed into one archive on your device, and come back as a single ZIP. 0 bytes uploaded
  1. Add your PDFs

    Drop the PDFs you want to send together.

  2. Check the settings

    Name the archive, and number the files if their order matters.

  3. Save the result

    Save one ZIP. Anyone can open it on Windows, macOS, iOS or Android without installing anything.

Why it doesn’t upload

Bundles of PDFs are often a whole application or case file. Zipping them here keeps the full set on your device.

Worth knowing

  • PDFs are already compressed, so zipping them usually saves only a little space. To make the PDFs themselves smaller, compress them first.
  • Files with the same name get a number added so none is overwritten.
  • The ZIP has no password. To lock the documents themselves, encrypt the PDFs before zipping them.

Under the hood

What happens to your file

The files are packed into a ZIP archive in memory with fflate. PDFs and images are already compressed, so they are stored rather than squeezed again — which is faster and makes the same size of archive. Nothing inside any file is changed.

Questions

How do I put multiple PDFs into one ZIP file?

Drop them here and press Make ZIP. You get one .zip file containing every PDF.

Does zipping a PDF make it smaller?

Only slightly — PDFs are compressed inside already. For a real reduction, compress the PDFs.

How do I zip a PDF on Windows or a Mac?

On Windows 11, right-click the file and choose Compress to ZIP file (on Windows 10, Send to → Compressed (zipped) folder). On a Mac, Control-click it and choose Compress. This page does the same in any browser, and can number the files so their order survives.

How do I zip a PDF on an iPhone or Android phone?

Open this page in Safari or Chrome, choose the PDFs and press Make ZIP; the archive is saved to Files or Downloads. On an iPhone, the Files app can also do it: press and hold the PDF and choose Compress.

Can I upload a ZIP to a portal that asks for one file?

If the portal accepts ZIP files, yes. Many don’t; if it wants a single PDF, merge them into one instead.
