Free online POD to PDF converter

A reader, archive system, or document workflow may accept PDF but not Perl’s POD source format. Converting POD to PDF produces a fixed-layout file that can be printed, shared, archived, or viewed without Perl documentation tools.

What the POD format is

POD means Plain Old Documentation, Perl’s lightweight markup language for documenting programs and modules. It appears in standalone .pod files and in documentation sections embedded in .pm modules and .pl scripts.

Directives such as =head1, =head2, =over, =item, and =cut define headings, lists, and the boundary between documentation and Perl code. Perl distributions, CPAN packages, source repositories, Perl manuals, and Unix documentation workflows commonly use POD. POD describes document structure rather than exact pages, so its appearance depends on the renderer.

What the PDF format is

PDF is a page-oriented format that stores page dimensions, text placement, fonts, images, links, and vector graphics. It normally preserves pagination and layout across operating systems and PDF viewers, making it suitable for printing, sharing, archiving, and document-management systems.

PDF is a distribution format rather than an ideal editable source. Keep the original .pod, .pm, or .pl file for future changes.

How to convert POD to PDF

Use 101convert.com

1. Open the POD-to-PDF converter on 101convert.com.
2. Upload the source .pod file, or select a supported Perl source file containing POD documentation.
3. Choose PDF as the output format and start the conversion.
4. Download the generated PDF and inspect its headings, lists, code blocks, links, characters, and page breaks.

This option requires no Perl or LaTeX installation and is available free on 101convert.com. Do not upload confidential source code or private documentation unless the service’s handling and retention terms are acceptable.

Convert locally with HTML

pod2html is included with many Perl installations. On Windows, Strawberry Perl supplies Perl and commonly used POD utilities.

1. Open a terminal in the directory containing the source.
2. Generate HTML from a standalone POD file:

pod2html --outfile=manual.html manual.pod

The same command can process a module or script containing POD:

pod2html --outfile=manual.html Module.pm

Only the POD sections are rendered; Perl code outside those sections is not executed or formatted as documentation.

3. Open manual.html in Chrome, Chromium, Microsoft Edge, or Firefox.
4. Choose Print → Save as PDF, select the paper size and margins, and save the result as manual.pdf.
5. Review headers, footers, scaling, background graphics, links, code indentation, and page breaks before distributing the file.

For repeatable browser-based output, Chromium can print the HTML without opening a dialog:

chromium --headless --disable-gpu --print-to-pdf=manual.pdf file:///absolute/path/manual.html

Replace chromium with the installed executable name. Use an absolute file:// URL; relative paths can fail in headless mode.

Convert locally with LaTeX

pod2latex creates a LaTeX document, which a LaTeX distribution such as TeX Live or MiKTeX can compile into PDF. The utility may need to be installed separately from Perl.

1. Generate LaTeX from the POD source:

pod2latex -out manual.tex manual.pod

2. Compile the generated file:

pdflatex manual.tex

Run pdflatex again when the document contains a table of contents or cross-references. This method can provide more consistent typography and long-document pagination than browser printing, but its output depends on the installed LaTeX packages and fonts.

Control layout and encoding

For HTML output, add a stylesheet:

pod2html --css=manual.css --title="Manual" --outfile=manual.html manual.pod

Print CSS can set page margins and discourage code blocks from splitting:

@page { margin: 20mm; } pre { break-inside: avoid; }

The browser’s print settings still control paper size, scaling, headers, footers, and background rendering. Keep local stylesheets and referenced images available when opening the HTML.

Declare the source encoding when non-ASCII characters are present:

=encoding utf8

Place the declaration near the beginning of the POD document. The selected browser or LaTeX engine must also use a font containing the required glyphs.

Quality and compatibility limits

Different POD renderers can place headings, lists, verbatim code, links, and tables differently. pod2html and pod2latex may not reproduce terminal output, Unix man-page styling, custom formatter behavior, raw HTML, formatter-specific directives, or nonstandard POD extensions exactly.

Inspect nested lists, indented code, escaped characters, Unicode symbols, hyperlinks, images, tables, and page breaks. Links to local files, installed modules, or generated manual pages may be unusable after conversion. Very long code blocks can still split across pages even when break-inside: avoid is specified. Missing glyphs usually appear as empty boxes and require a Unicode-capable font. Retain the POD source as the authoritative editable document.
