Most basic file conversion

Before we go in to details, short usage example how to convert DOCX file to PDF.

convertapi --iformat=docx --oformat=pdf --params="file:@/path/to/test.docx" --out="@/path/to/resultdir" --secret=your-api-secret

Arguments documentation

--iformat

Input file format (file name extension). All supported input formats can be found here. Example:

--iformat=docx

--oformat

Output file format (file name extension). All supported output formats can be found here. Example:

--oformat=pdf

--params

Conversion parameter list. All supported conversion parameters can be found here. Parameter name and value is separated by : colon. Parameters are separated by , comma. Example:

--params="param1:value1, param2:value2, param3:value3"

File parameter

Special case is file parameter. Value can have prefix and can be provided as an array with ; semicolon separator. Prefix can be one of those:

no prefix

No prefix means that value is http or https scheme URL to file. Example:

--params="file:https://cdn.convertapi.com/cara/testfiles/presentation.pptx"

@

Parameter values starting from @ are treated as paths to local files or directories. Example:

--params="file:@/path/to/myfile.doc"

<

Parameters with < values are substituted with data taken from STDIN. As raw value can only be URL so in this case data received from STDIN should be URL or URL array separated by \n Example:

--params="file:<"

@<

Parameters with @< values are substituted with data taken from STDIN. Data received from STDIN should be local path to file or directory. Also can be an array of paths separated by \n. Example:

--params="file:@<"

<<

Parameters with << values are substituted with data taken from STDIN. Data received from STDIN should be file content. Example:

--params="file:<<"

Array parameter

If parameter name is suffixed with [] parameter gets treated as an array parameter. Mainly array parameters are used when one conversion needs to accept multiple files (e.g. pdf merge or zip compression).

--params="files[]:@/path/to/dir"

--out

Argument defines how conversion result should be outputted. Values can be one of those:

url

This is default output method. It prints to STDOUT URL or array of URLs that point to converted files. This method should be used for conversion chaining.

@

Value prefixed with @ is treated as local file or directory path where converted file will be stored.
Example:

--out="@/path/to/result.pdf"

--out="@/path/to/resultdir"

stdout

Conversion result will be outputted to STDOUT. If result consists of multiple files, second and other files will be outputted to file descriptors starting from 3.

Do PDF->JPG and DOCX->JPG conversions in parallel and ZIP result JPG files

( \
    convertapi --iformat=pdf --oformat=jpg --params="file:/path/to/dir" --secret=your-api-secret \
    & convertapi --iformat=docx --oformat=jpg --params="file:@/path/to/dir" --secret=your-api-secret \
) | convertapi --iformat=jpg --oformat=zip --params="files[]:<" [email protected]/path/to/resultdir  --secret=your-api-secret

Merge PDFs files from various locations: remote SSH server, local file, local directory, remote HTTP server. Save result file to remote SSH server. All this done without writing to disk.
