Free online PMX to PDF converter

People convert PMX source to PDF when they need printable sheet music, a fixed-layout score for sharing, or a copy that can be viewed without the PMX and MusiXTeX toolchain. PDF also provides a stable archival version while the original source remains editable.

What the PMX format is

In the Documents context, PMX is a text-based source format for the PMX preprocessor used with the MusiXTeX music-typesetting system. It describes notes, rhythms, voices, lyrics, instruments, and page layout; it is not a finished page image or rendered score.

Composers, arrangers, and music typesetters create or edit PMX files with PMX tools and text editors. A project may also contain generated .tex files, MusiXTeX macros, music fonts, lyric files, and other referenced resources. Renaming .pmx to another extension does not convert the source.

What the PDF format is

PDF stores the composed pages in a fixed layout, including text, notation, spacing, and normally embedded or referenced fonts. It is suitable for printing, distributing sheet music, submitting a score, and archiving a version that does not require PMX or MusiXTeX.

PDF is not a convenient replacement for the source: changing musical structure, lyrics, or layout is substantially easier in the original .pmx and its related files. Keep the complete source project with the exported PDF.

How to convert PMX to PDF

The dependable method is local typesetting with a TeX distribution, MusiXTeX, and the PMX distribution. TeX Live supports Linux, macOS, and Windows; MiKTeX can be used on Windows when the required MusiXTeX packages are available. PMX itself may need to be installed separately from its distribution or CTAN source.

1. Install TeX Live or MiKTeX, MusiXTeX, and PMX. Confirm that pmxab and the MusiXTeX wrapper command are available in the system PATH.
2. Put the source file and every referenced file in one working directory. Check filenames, relative paths, custom macros, fonts, and included graphics.
3. Open a terminal in that directory and run pmxab score.pmx. This normally generates a MusiXTeX-compatible file such as score.tex.
4. Run the MusiXTeX build wrapper, usually musixtex score or musixtex score.tex, according to the installed distribution. The wrapper performs the TeX and auxiliary-file passes needed for music spacing and normally produces score.pdf.
5. Open the PDF and inspect every page, including system spacing, lyrics, tuplets, accidentals, page turns, line breaks, and final barlines.

Command names and wrapper behavior vary between PMX and MusiXTeX releases. If the wrapper is unavailable, use the build procedure supplied with that release rather than assuming that one pdflatex run is sufficient. A generated PMX file may require the traditional TeX, musixflx, and repeated TeX passes, followed by PDF generation.

On Windows, run the commands in Command Prompt or PowerShell after adding the TeX, MusiXTeX, and PMX directories to PATH. A PMX distribution may also provide a batch file or graphical Build or Typeset command.

Online conversion options

General file-conversion websites and office-document converters normally do not parse PMX notation, so they are not reliable direct-upload options. Overleaf can compile a generated MusiXTeX .tex project when the required packages and support files are uploaded, but it is not a direct PMX converter because the PMX preprocessing step generally must be performed locally first. Local compilation is preferable for unpublished scores or projects containing proprietary material.

Quality and compatibility

Output depends on compatible PMX, MusiXTeX, TeX, macro, and music-font versions. Missing packages or referenced files can stop compilation or produce incomplete notation; retain the compiler log when diagnosing errors.

PMX uses structured, syntax-sensitive source rather than ordinary word-processing text. If page breaks or spacing are wrong, change the relevant PMX layout settings and regenerate the PDF. Editing notation directly in a PDF can alter placement without correcting the underlying music. Keep the original source and record the tool versions used to create the final PDF.
