How to Enhance Faded Handwritten Text in Acrobat Pro XI
Question details
The user wants to darken or enhance faded handwritten text in an old scanned document without paying for expensive monthly add-ons.

- Product
- Adobe Acrobat Pro XI
- Device & OS
- not provided
- Scenario
- Editing an old scanned PDF document that contains faded handwritten text.
- Observed behavior
- Acrobat Pro XI prompts for a $19.90 per month add-on to enhance the text, leaving the user unsure if the feature is natively included in the software.
Locate the original scanned image files if you still have them, as adjusting brightness and contrast is much easier in a dedicated photo editor before importing into a PDF.
Extract and Adjust the Image Using an External Editor
Since Acrobat Pro XI does not natively enhance faded handwriting without a paid add-on, extracting the image and adjusting it in an external photo editor is the most effective method.
PDF editors treat scanned pages as flat images. To darken handwriting, you need to manipulate the image's contrast and brightness directly.
Open your document in Acrobat Pro XI. Go to 'File' > 'Save As Other' > 'Image' and select either JPEG or PNG to extract the scanned page.
Right-click the exported image file and open it in a standard image editing application like Windows Photos, Adobe Photoshop, or GIMP.
Navigate to the adjustment settings in your image editor. Lower the brightness slightly and increase the contrast to make the faded handwriting stand out against the page background.
Save the enhanced image. Open Acrobat Pro XI, go to 'File' > 'Create' > 'PDF from File', select your new image, and save the final enhanced PDF.

Verify and Install a Dedicated PDF Plug-in
If you frequently work with faded scanned documents and prefer not to use external editors, utilizing a specialized plug-in might be worth the investment.
Manage and Edit Scanned PDFs Effortlessly with WPS Office
WPS Office provides a comprehensive PDF toolkit that allows you to easily extract, convert, and manage scanned documents without the need for expensive monthly add-ons.
- 1. Open your PDF: Launch WPS Office and open your scanned PDF document containing the faded handwriting.
- 2. Convert PDF to Picture: Navigate to the 'Tools' tab and click on 'PDF to Picture' to export your scanned pages as high-quality image files.
- 3. Enhance the image: Use your computer's built-in photo viewer to increase the image contrast, darkening the handwritten text.
- 4. Convert Picture to PDF: Return to WPS Office, use the 'Picture to PDF' tool from the 'Tools' tab, and select your newly enhanced images.
- 5. Save your enhanced document: Click 'Export to PDF' to save your updated, highly legible scanned document.

Frequently Asked Questions
Why is my scanned handwritten text so faded in the PDF?
Scanners often struggle to capture light ink or pencil marks accurately, resulting in low contrast images. Adjusting the scanner's hardware settings to a higher DPI and higher contrast before scanning can prevent this issue.
Does Adobe Acrobat Pro XI include built-in OCR for handwriting?
Acrobat Pro XI includes basic OCR (Optical Character Recognition) for standard printed text, but it generally cannot recognize or enhance cursive or faded handwriting. Dedicated add-ons or specialized handwriting recognition tools are required for that.
Can I darken PDF text without converting it to an image?
If the text in your PDF is recognized as digital font text, you can easily change its font color or make it bold using the 'Edit Text & Images' tool. However, if the document is a scanned image, the text is flattened into the picture, meaning you must modify the image's overall contrast to darken the writing.
