Frequently Asked Questions
Why does the OCR feature cause PDF software to crash?
OCR (Optical Character Recognition) is a resource-intensive process. Crashes usually happen due to corrupted application files, an excessively high image DPI in the scanned document, damaged system fonts, or leftover plugin conflicts from older software versions.
Will running the Acrobat Cleaner Tool delete my saved PDF files?
No. The Acrobat Cleaner Tool only removes the application's installation files, registry keys, and software preferences. Your personal PDF documents and scanned files saved on your computer will remain completely safe and untouched.
Can I recognize text on a PDF if my current software keeps crashing?
Yes. If your current software continues to crash, you can use alternative PDF editors like WPS Office, which include robust, built-in OCR tools specifically designed to handle and convert scanned documents smoothly.
