Make a Scanned PDF Searchable
on iPhone, privately.

A scanned PDF is a picture of text, not text — you cannot search it, select it or copy a line from it. Filemorph reads the page images with on-device OCR and adds a real text layer, right on your iPhone.

Filemorph adding a searchable text layer to a scanned PDF on iPhone

Old scanned contracts, a stack of receipts run through a scanner app, a PDF made from photographed pages: none of it is searchable until something reads the text on the page and adds it back into the file. Filemorph does that pass locally, without sending a single page anywhere.

Filemorph runs Apple's Vision framework over each page image to recognize the text, then overlays an invisible, selectable text layer aligned to what is on the page — the visual scan looks exactly the same, but search, Spotlight and copy-and-paste now work on it. Recognition quality depends on scan quality and the language of the text; available languages depend on what your iOS version supports.

How to make a scanned PDF searchable on iPhone

Pro
  1. Add your scanned PDF. Open Filemorph and pick the scanned PDF from Files, Photos or the Share sheet.
  2. Choose OCR Overlay. Tap Transform and choose OCR Overlay to run on-device text recognition.
  3. Save or share. Tap Convert. The PDF saves locally with a searchable text layer, unchanged visually.

In the app: Transform → OCR Overlay.

Why make a scanned PDF searchable?

A searchable PDF lets you find a name, a date or an amount instantly instead of scrolling through pages by eye. It also makes the document usable downstream — you can select and copy text, or run PDF to Text or PDF to Word on it, none of which work on a plain image scan.

Is it private?

Yes. Unlike web converters that upload your files to a server, Filemorph converts every file locally using Apple's frameworks. Nothing leaves your device, and it works with no internet connection. This operation is part of Filemorph Pro ($29.99/year, 7-day free trial on monthly and annual plans).

FAQ

Scanned PDF → Searchable PDF — common questions.

Does OCR change how the PDF looks? +

No. The original page images are untouched; Filemorph adds an invisible text layer on top, aligned to the text in the scan.

Is this a cracking or password-removal tool? +

No. OCR Overlay adds searchable text to a scan you already have full access to — it has nothing to do with passwords or encryption.

What languages does OCR support? +

Vision supports a range of languages, and availability depends on your iOS version and installed language support.
