ExtractPDF FAQ:

1. Why do the extracted images look different from those in the PDF file?

This tool extracts the original images from the PDF file. Image processing performed within the PDF, such as cropping, rotation, and color inversion, will be ignored.

2. Why are there missing glyphs in the fonts extracted from the PDF file?

When a font is embedded in a PDF file, the PDF file only contains the glyphs of all characters that appear. If your PDF file does not contain the letter "P", then the extracted font file will not contain the letter "P" either.

3. Why does typesetting look strange when using a font file extracted from a PDF?

PDF files typically do not contain font specification files (.pfm or .afm files) because PDF readers don't require this information. The absence of font specification files will cause the extracted font files to be unusable.

4. Is it legal to extract font files from a PDF?

Extracting font files from a PDF is legal. However, if you want to use the extracted font files, you need to obtain authorization from the font's creator.

However, due to the absence of font metric data, extracted font files generally cannot be used directly. They are mainly used to help identify the fonts used in PDF files.

If you insist on using fonts extracted from PDF files, you need to understand the legal risks involved in using them.
