Slow Performance When Editing Large PDFs with OCR Issue: When working with large scanned documents or using Optical Character Recognition (OCR), Acrobat may exhibit significant performance degradation, such as slow rendering, long saving times, or freezing. Workaround: Break the document into smaller sections before applying OCR to reduce the processing load. Adjust OCR settings to Searchable Image (Exact) instead of Editable Text, as the latter requires more processing power.
