Convert PPTX to PDF using LibreOffice headless mode with safe parallel conversion

fast-pptx-pdf

Convert PPTX files to PDF using LibreOffice in headless mode, with safe parallel conversion via per-worker profiles.

• Simple API: convert_file(path) and convert_folder(path, workers=8).
• CLI: fast-pptx-pdf file.pptx or fast-pptx-pdf folder/ --workers 8.
• No profile locking: Each worker uses its own LibreOffice profile in a temp directory.
• Robust: Timeouts, optional retries, and clear errors.

Python cannot natively render PowerPoint files; this library uses the LibreOffice command-line interface. COM automation (Windows) is not thread-safe; LibreOffice headless runs one process per conversion and is suitable for parallelism when each process has a separate profile.

Requirements

• Python 3.8+
• LibreOffice installed and on PATH, or set FAST_PPTX_PDF_LIBREOFFICE to the path to soffice (or its program directory).

Installing LibreOffice

• Windows: Download the installer, or use winget install TheDocumentFoundation.LibreOffice.
• Linux: e.g. sudo apt install libreoffice (Debian/Ubuntu) or your distribution’s package.

Install

pip install fast-pptx-pdf

Usage

Python API

from fast_pptx_pdf import convert_file, convert_folder

# Single file (output PDF next to the PPTX by default)
pdf_path = convert_file("slides/presentation.pptx")
# Optional: output directory, timeout, retries
pdf_path = convert_file("deck.pptx", output_dir="pdfs/", timeout=60, retries=1)

# Folder: convert all .pptx in parallel (workers default: min(cpu_count, number of files))
successes, failures = convert_folder("slides/")
successes, failures = convert_folder("slides/", workers=8, continue_on_error=True)

CLI

# Single file
fast-pptx-pdf presentation.pptx

# Folder (default workers)
fast-pptx-pdf slides/

# Folder with 8 workers
fast-pptx-pdf slides/ --workers 8

# Optional: timeout, retries, LibreOffice path, continue on error
fast-pptx-pdf slides/ --workers 4 --timeout 60 --retries 1 --continue-on-error
fast-pptx-pdf file.pptx --libreoffice "C:\Program Files\LibreOffice\program\soffice.exe"

Configuration

• LibreOffice path: Set the environment variable FAST_PPTX_PDF_LIBREOFFICE to the full path to soffice or to the LibreOffice program directory. The library also searches PATH and common install locations (e.g. Windows Program Files, Linux /usr/bin/soffice).
• Workers: For convert_folder, if workers is not set, it uses min(cpu_count, number_of_pptx_files).
