Get the original pictures back
Taking screenshots of a PDF loses quality. Extract images saves the pictures stored inside the file instead: JPEG photos come out byte for byte as they are in the PDF (no re-compression), and other pictures become lossless PNG files, keeping any transparency. They come together in a ZIP file.
Good to know
- Pictures smaller than 48 pixels (icons, bullets, lines) are skipped; untick Skip small images to get them all.
- A picture is saved at the resolution stored in the PDF. If it looked small and blurry in the document, it will here too.
- Drawings made of lines and shapes (many charts and logos) aren't pictures, so they aren't extracted. Save the whole page with PDF to PNG instead.
- A scanned PDF holds one picture per page: you get the scans themselves.
Respect copyright
Pictures in a document belong to their authors. Extract them for your own work, archives or to reuse your own material, and ask permission before publishing someone else's.
