Command-line mode
Short answer: EnjoyPDF can run without a window: --replace replaces one term, --batch uses a keyword table, --redact runs secure redaction, and --folder processes a whole folder. Exit code 0 means success, 1 failure, 2 usage error, 3 written but verification found problems.
Usage
PDFTextReplacer.exe --replace <input> <output> <find> <replace> [password]
PDFTextReplacer.exe --batch <input> <output> <keyword-table.xlsx|csv|txt> [password]
PDFTextReplacer.exe --redact <input> <output> [keywords.txt] [password]
PDFTextReplacer.exe --folder <input-folder> <output-folder> <keyword-table.xlsx|csv|txt>--folderprocesses every PDF and image in the folder, including subfolders. It prints progress file by file and writes a processing report to the output folder.- To replace with nothing, pass
"". - Output messages follow the interface language setting. You can also set it with an environment variable such as
PDF_UI_LANG=en.
