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?
Image-only scans have no text mappings to edit. Recognize the text with OCR first.
Can one glyph map to multiple characters?
Sure. Text displays correctly, supporting ligatures, combining characters, emojis, and other Unicode content; all instances using the same font and original encoding are updated simultaneously.
