Question details
The user wants to know why the spell checking feature does not seem to work or produce visible results when running the Adobe Acrobat PDF Optimizer.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Optimizing a PDF document and expecting the software to automatically find and correct spelling errors.
- Observed behavior
- Enabling spell checking during PDF optimization does not behave like a standard word processor spell checker and yields no visible spelling corrections in standard text.
Verify whether your PDF document contains standard selectable text or if it is a scanned image, as this determines which type of spell checking and text recognition tools you need to apply.
Use Acrobat OCR to Correct Scanned Text Recognition Errors
Use this method if you are working with scanned documents. Acrobat's spell checker is designed primarily to fix Optical Character Recognition (OCR) suspects rather than standard authoring typos.
In Adobe Acrobat, the spell checking function tied to PDF optimization and scanning is intended to improve text searches. It does this by allowing you to review 'suspects'—words the OCR engine was unsure about during text recognition.
Because it does not function like a traditional word processor spell checker, it will not auto-correct standard misspelled words in a normally authored PDF document.
Open your scanned PDF in Acrobat, navigate to the Tools menu, and select 'Scan & OCR'.
Click on 'Recognize Text' and choose 'In This File' to process the scanned image into searchable text.
After recognition, click on 'Recognize Text' again and select 'Correct Recognized Text'. Acrobat will highlight OCR suspects for you to review, accept, or correct.
Edit PDF Text Directly to Fix Standard Typos
Use this method if your document contains natively generated text and you need to correct standard spelling mistakes.
Easily Edit and Spell Check PDFs with WPS Office
Unlike standard PDF optimizers that limit spell checking to OCR suspects, WPS Office provides an intuitive, word-processor-like editing experience for your PDF files. You can easily modify text, correct standard typos directly, and perform accurate OCR on scanned documents.
- 1. Open Your PDF: Launch WPS Office and open the PDF document you need to check or edit.
- 2. Enter Edit Mode: Navigate to the 'Edit' tab located on the top ribbon and click the 'Edit Text' button.
- 3. Correct Spelling Errors: Click directly on any text block to modify the text and correct typos just like you would in a standard word processor.
- 4. Utilize OCR for Scans: If you are using a scanned document, select the 'OCR' tool to extract the image text into a fully editable format.
Frequently Asked Questions
What does Acrobat spell checking actually do during PDF optimization?
During optimization and scanning, Acrobat's spell checking primarily works alongside the OCR (Optical Character Recognition) engine. It identifies and allows you to correct text recognition errors (suspects) to improve document searchability, rather than fixing standard authoring typos.
How can I fix normal spelling mistakes in a PDF?
To fix standard spelling errors, you should use the 'Edit PDF' tool to manually modify the text blocks. PDF Optimizer is not designed to replace a word processor's spell checker for standard text correction.
Why is my searchable PDF text still showing OCR errors?
If the OCR engine misidentified certain characters, the document might contain incorrect hidden text layers. Running the 'Correct Recognized Text' feature allows you to manually review these OCR suspects and correct recognition errors so your text searches work accurately.
