Hello,
Calling PDF experts out there. Are there tools to fix broken PDFs that give out the following errors? Those are very old files whose source files are unavailable. Thank you. Code:

Could it due to fonts? Here's the fonts it used: Code:

OCR is sometimes the only solution.
Loads of PDFs simply don't have sane text to copy. If I can't copy/paste from Okular or similar (Sumatra on Windows) into LO Writer, or Word, then it's time for OCR. |

I opened the file in Abbyy.
Oddly, it says "The content in this PDF file is protected with a password." File > Save As > Searchable PDF Document: "The document is already searchable and does not need to be converted." |

Make a copy with Ghostview, or Print to PDF.

Would you have the Ghostview command handy?
I ran the installer gs10021w64.exe, but no trace of gs.exe in "c:\Program Files\gs\gs10.02.1\bin\", and the following fails: Code:
"c:\Program Files\gs\gs10.02.1\bin\gswin64c.exe" -o EasyEccoV01N04.IMAGE.pdf -sDEVICE=pdfimage32 -dPDFSETTINGS=/screen EasyEccoV01N04.pdf '-o' is not recognized as an internal or external command, operable program or batch file.

A user could provide a different set of files, which open fine. Fixed.
Thank you. |

I've not used gs (ghostscript) or gv (ghostview) for nearly a decade, so no.
gs (ghostscript) = console utility gv (ghostview) = GUI that works as a viewer and controls ghostscript, so you don't bother with a command line and arcane arguments. |
