关于这种格式

Created by Adobe in 1993 and made an ISO standard (32000) in 2008. Its purpose is to look identical on every device, which is why it is used for contracts, invoices, papers and print — documents that must not change.

能承载的内容

  • Text, images and vector shapes
  • Embedded fonts
  • Multiple pages
  • Bookmarks, links and form fields
  • Passwords and signatures
  • Annotations

无法承载的内容

  • An editable document structure — paragraphs and tables keep their look but not their structure

转换为其他格式时

PDF → DOCXPage layout mostly survives, but paragraph, table and header structure is reconstructed by guesswork. A scanned PDF has no text at all and needs OCR first.
PDF → JPGEach page becomes one picture. Text can no longer be selected or searched.
PDF → TXTOnly the words remain; layout, images and table lines are gone.

打不开的时候

  • Password-protected — the open password and the edit password are different things
  • Truncated download — a file without %%EOF at the end is damaged
  • Not actually a PDF, just the extension

一句话 A scanned PDF and a text PDF look the same but are completely different. If you can drag to select words, it is text; if not, it is a scan.
