PDFTron's PDF2HTML is a command-line application designed to convert PDF documents to HTML files while preserving the contents of the PDF. This section covers the basic usage of PDF2HTML, explaining all of the available options.
The basic command-line syntax is:
pdf2html [options] -in inputfile -out outputfile
The '-in' parameter can be abbreviated as '-i', and the '-out' parameter can be abbreviated as '-o'.
If you are calling PDF2HTML from the console or a BAT file, you may use relative file names. However, if you are calling it from an application or a server, you should be using absolute file names.
See more options in Command-Line Summary for PDF2HTML.
pdf2html -in my.pdf -out my.html
The '-in' (or '-i') parameter is used to specify the input file. You can use relative and/or absolute file name.
The '-out' (or '-o') parameter is used to specify the output file. You can use relative and/or absolute file name.
pdf2html -in my.pdf -out myOut.html
pdf2html -in my.pdf -out outHTM.htm
pdf2html -password MyPDFPassword -in my.pdf -out myOut.html
pdf2html -pages 1-2 -in my.pdf -out my.html
pdf2html -in *.pdf'.
pdf2html -in a.pdf b.pdf c.pdf -out a.html b.html c.html
To provide additional feedback, PDF2HTML returns exit codes after completing processing. The exit codes can be used to provide user feedback, for logging, etc. This is particularly important for applications running in an unattended environment.
The following table lists possible exit codes and their descriptions:
Exit Code Description --------------- --------------------------------------------------------------- 0 All files converted successfully. 1 Invalid parameter. One or more parameters were invalid. 2 License problem. Invalid license; license or evaluation expired; the feature you are trying to use is not enabled with the license you have. 3 Cannot open input. Input file name is invalid; file does not exist; network is unavailable; drive was ejected; not enough permissions to access the input file. 4 Cannot create output. Output file name is invalid; network is unavailable; drive was ejected or full; another application has opened the same file; not enough permission to create the output file. 5 Invalid input. Input file exists, but it is invalid. Usually indicates an invalid or corrupt PDF, or any other input file parsing problem, other than password problems. 6 Invalid output. Output file was created, but it is invalid. There were some problems, such as fonts could not be embedded, some issues that make the output corrupt. 7 Encrypted input. Input file is encrypted, and there is no password, or the password is invalid, or the password does not give permission to complete the requested operation. 8 Timeout. The whole or part of the operation has timed out. You may get better luck by increasing the timeout, because some operations take a lot of time to complete. 9 Cancelled. The operation has been cancelled. This is very unlikely in an SDK, which has no user interaction. 10 Access denied. Temporary file could not be created; registry could not be accessed; any other system-level denial of access. Exception: If the input or output file cannot be accessed, the error codes 3 and 4 are used instead. 17 Invalid setup. The product is not set up correctly. Files or registry got corrupted. Please reinstall. 18 Out of memory. There was not enough memory to complete the operation. Note: It is not guaranteed that you get this error when you run out of memory. You could also get 19 - Internal error. 19 Internal error. Invalid operation; unknown error; crash; access violation. 20 Page too large. PDF page is too large for HTML.
All codes other then '0' indicate that there was an error during the conversion process.
The following illustrates a sample Windows batch script that processes exit codes:
@echo off rem convert my.pdf to my.html in the current working folder pdf2html -in my.pdf -out my.html if errorlevel 19 goto othererror if errorlevel 3 goto inputerr if errorlevel 0 goto exit :inputerr echo No input files specified. goto exit :othererror echo An error encountered during processing. goto exit :exit
