OCR PDF (Make Scanned PDF Searchable) on a scanned PDF

Scanned PDFs need slightly different handling. Here's how OCR PDF (Make Scanned PDF Searchable) works with scanner output specifically.

If you've ended up here, you have a PDF and a specific job: scanned document. The defaults most software ships with aren't tuned for that — they're tuned for "archive everything at maximum quality," which is the opposite of what you need now.

Why scanned document needs different settings

A PDF for scanned document optimises for things the original PDF doesn't care about: small enough to upload quickly, compatible with whatever software the recipient is using, and free of embedded metadata that could leak personal information. The defaults give you the opposite — large, high-quality, metadata-rich. Useful for some jobs, wrong for this one.

What to verify before sending

Quick check-list once OCR PDF (Make Scanned PDF Searchable) finishes:

  • Open the result. Make sure it looks right at the size the recipient will actually see it.
  • Check the file size. Match it against the limit you're targeting.
  • Confirm the file extension. Sometimes you need to rename — for example, a recipient who expects .jpg won't necessarily accept .jpeg.
  • Send a test to yourself first. Open the test on the same device the recipient will use, if you can.

Frequently asked questions

Does compressing a PDF make it look unprofessional for scanned document?

Not when done right. Sensible compression at the "balanced" preset produces output indistinguishable from the original to the human eye, even at half the size.

Can I undo the compression later?

No — compression is one-way. Always keep the original PDF archived somewhere, and treat the compressed version as a send-only copy.

Will OCR PDF (Make Scanned PDF Searchable) work for a batch of PDFs?

Yes — drop multiple files at once. All of them get the same scanned document settings applied, then downloaded as a folder.

What if the recipient asks for the original?

Keep the original. OCR PDF (Make Scanned PDF Searchable) produces a copy; the source file you dragged in is never modified.
