Frequently Asked Questions
Will repairing the PDF change its appearance?
The tool updates the ToUnicode mappings used to copy and extract text, preserving the original font data, drawing codes and page content.
Can I repair scanned documents?
Scans containing only images do not have editable text mappings. This tool’s OCR only aids in recognizing existing font characters and does not generate a text layer for images.
Can one glyph map to multiple characters?
Sure. Correct text supports Unicode features like ligatures, combining characters, and emojis; all occurrences using the same font and source encoding will be updated simultaneously.
