How do I make my scanned PDF searchable using Scan & OCR?

Open your PDF in Acrobat. Go to 'All tools' > 'Scan & OCR'. Select 'In this file' and set your page range and language. Click 'Recognize Text'. Acrobat will add a searchable text layer to your document.

What is the difference between an image-only PDF and a PDF with renderable text for OCR?

Feature Image-only PDF PDF with Renderable Text. Content Pages are pictures of text, not actual text. Pages contain real, selectable text. OCR Compatibility OCR works well; it adds a searchable layer. OCR fails and shows an error; it's not needed. Purpose Scans of paper documents. Documents created digitally (e.g., from Word).

If my scanned document is blurry, how can I improve the OCR accuracy?

Rescan the document at a higher quality, ideally 300 dpi, to get a clearer image. Ensure the document is flat and well-lit during scanning to avoid shadows. Check the original paper document for clarity before scanning again. Select the correct OCR language in Acrobat to help the software interpret even slightly unclear text better.

I’m teaching a new junior advisor to check scanned beneficiary forms for completeness and searchability before filing. I’m worried they’ll miss a faded signature or a non-searchable PDF and cause a compliance gap. Tell me the exact checks they must run on each scan, one simple script to say on the call to get better scans from clients, and how I should verify their work the first five times.

when the reply comes backPush once: ask it to sharpen the weakest part, and to say what it assumed.

Configure the OCR settings as needed for your documents (such as language and output style).
RecommendationSet the OCR language to match your documents for best accuracy.
6
Add any additional steps required for your workflow (such as saving or moving files).
7
Under Files to be processed, specify whether the action will run on open files, a folder, or prompt for files each time.
8
Save the action with a descriptive name.
9
Run the action by selecting it from the Action Wizard list and following the prompts to select your PDF files.
Best practiceBatch processing with Action Wizard is the most reliable way to automate OCR in Acrobat; scripting support for OCR is limited.

In the appWith the API

You can save your OCR workflow as an Action to quickly process multiple PDFs with the same settings in the future.

This runs in the Acrobat app - there is no separate API for this task.

OCROCR stands for Optical Character Recognition. It is technology that turns images of text into real text you can search and copy.ExampleAfter scanning a paper invoice, OCR allows you to copy the vendor's name from the image.

DPIDPI means dots per inch, and it tells you how clear an image is when it is scanned.ExampleA scanned photo saved at 300 DPI will usually contain more detail than the same photo at 72 DPI.

Searchable LayerA hidden layer of text added to an image-based PDF, allowing you to search for words within the document.ExampleThe hidden searchable layer in the scanned contract allowed us to find specific clauses.

about this task

Open your PDF in Acrobat.
Go to 'All tools' > 'Scan & OCR'.
Select 'In this file' and set your page range and language.
Click 'Recognize Text'. Acrobat will add a searchable text layer to your document.

Choosing the correct OCR language is important because it helps Acrobat understand the specific characters and grammar of that language. If the wrong language is chosen, the text recognition will be less accurate, leading to more errors in the searchable layer. Always pick the language that matches the text in your scan for the best results.

The primary benefit of converting scanned documents to searchable PDFs is the ability to quickly find specific information within them. Before OCR, a scanned document is just an image, and you cannot search for words. After OCR, a hidden text layer is added, allowing you to use search functions, copy text, and index documents for easier archiving and retrieval. This saves a lot of time compared to manually reading through every page.
