Private by design

Your files are opened and processed by your browser on this device. They are never uploaded to openWorkstand or anyone else, so the Merge PDF is safe for contracts, IDs, photos and work documents, and it keeps working offline once the page has loaded. How local processing works

Good to know

  • Password-protected PDFs must be unlocked first with Unlock PDF (you need the password).
  • Very large files are limited by your device’s memory; on a phone, split huge files into smaller parts first.

When to use the Merge PDF

  • Combine the pages of a scanned contract into one file before emailing it.
  • Merge monthly bank statements into a single PDF for a loan application.
  • Join lecture handouts or chapters into one document to read on a tablet.

Examples

One file for a job application

The portal accepts a single upload, but you have a CV, a cover letter and two certificates as separate PDFs. Drop all four files, drag the CV to the top and the certificates to the end, then merge. The result keeps every page in that order.

Receipts for an expense claim

If the receipts are photos, turn them into a PDF with JPG to PDF first, then merge that PDF with the expense form. If the result is too large to email, run it through Compress PDF.

Troubleshooting

Pages are in the wrong order

Drag the files into the order you want before clicking Merge; the first file becomes the first pages. To reorder single pages afterwards, use Organize PDF.

The file does not open

Check that it is one of the supported formats above and opens in another app. Damaged files and password-protected PDFs cannot be read until they are repaired or unlocked.

It is slow or stops on a very large file

Everything runs on your device, so speed depends on its memory. Close other tabs, use a computer rather than a phone, or split the file into smaller parts first.

The download did not start

Look for your browser’s download bar or icon. Some browsers ask once before a site may download files; allow it and click the button again.

Frequently asked questions

Are my files uploaded?

No. Your files are processed on your own device by your browser. They never leave your computer or phone, and there is no file size limit other than your device’s memory.

Can I merge password-protected PDFs?

Unlock them first with the Unlock PDF tool (you need the password), then merge the unlocked copies.

Is it really free?

Yes. There is no sign-up, no watermark, no daily limit and no paid plan. openWorkstand is paid for by a few ads on its public pages.
