Bash Command Line Interface for the Zamzar API - convert files to 100s of formats direct from the command line.
Latest commit 03ada41 Feb 3, 2015 @louismrose louismrose Fix #3. Convert source files with double spaces in their filename.
Previously, the default internal field separator (IFS) was being used. This is "<space><tab><newline>" and 2 or more repeated characters was reduce to a single separator during substitutions. To fix this, IFS is now cleared before making any substitutions that involve filenames. (Filenames can contain any character so there are no safe characters to use as the IFS).

This repository provides a simple Bash Command Line program ( for using the REST-based Zamzar file conversion API. It has been tested on OSX but should also work with cygwin (on Windows) and Linux since it uses standard Bash conventions.

You will need to have cURL installed on your system to use this script.

If you find any issues please raise them against this repository, since it is monitored by the Zamzar development team. We welcome pull requests and suggestions for improvements. The code in this repository is MIT licensed.



  • To find out what "to" formats are available for conversion for a given input file:

    ./ ~/portrait.jpg

    … should output:

    - bmp (1 credits)
    - gif (1 credits)
    - ico (1 credits)
    - pcx (1 credits)
    - pdf (1 credits)
    - png (1 credits)        
    - ps (1 credits)
    - tga (1 credits)
    - thumbnail (1 credits)
    - tiff (1 credits)
    - wbmp (1 credits)
    - webp (1 credits)
  • To convert a file into a different format and automatically download and save it to your current working directory with the same name and the file extension of the converted format:

    ./ ~/portrait.jpg png

    … should output:

    Job 313 is successful
    Downloading converted file(s) for job 313
    Converted file (id #2870) saved to: portrait.png
  • To convert a file into a different format and automatically download and save it to a different directory:

    ./ ~/portrait.jpg png ~/Downloads/
  • To print out the version of the script being used:

    ./ -v
  • To run a conversion in "debug" mode (useful for examining the cURL commands being run under the covers):

    ./ -d ~/portrait.jpg png
