Pptx Pdf Font Fix OpenClaw Plugin & Skill | ClawHub

Looking to integrate Pptx Pdf Font Fix into your AI workflows? This free OpenClaw plugin from ClawHub helps you automate web & frontend development tasks instantly, without having to write custom tools from scratch.

What this skill does

Fix PowerPoint font embedding issues in PDF export by patching text transparency in PPTX files. Use when a user has a PPTX file where exported PDFs show wrong/default fonts instead of the intended downloaded/custom fonts, even with font embedding enabled. Works by applying minimal (1%) transparency to fully-opaque text runs, which forces PowerPoint to properly embed fonts during PDF export.

Install

ClawHub CLI 
openclaw skills install @chernojagne/pptx-pdf-font-fix
Node.js (npx) 
npx clawhub@latest install pptx-pdf-font-fix

PPT Font Fix

Problem

PowerPoint's "Export to PDF" can fail to embed downloaded/custom fonts, substituting built-in defaults, even when:

  • Fonts are properly installed and embeddable
  • "Embed fonts in the file" is checked in PowerPoint options

Workaround

Applying a tiny transparency (1%) to text with 0% transparency forces PowerPoint to correctly embed fonts in PDF output. This is visually imperceptible but changes how PowerPoint processes the font during export.

Usage

python3 scripts/fix_font_transparency.py input.pptx [output.pptx] [--transparency 1]

Options

  • output -- Output PPTX path (default: input_fixed.pptx)
  • --transparency, -t -- Transparency % to apply (default: 1)

Behavior

  • Only patches text runs that are fully opaque (0% transparency)
  • Leaves text that already has any transparency untouched
  • Safe to run multiple times
  • Only modifies slide XML (ppt/slides/slideN.xml), not layouts/masters

Workflow

  1. Receive PPTX file from user
  2. Run the fix script: python3 scripts/fix_font_transparency.py input.pptx
  3. Return the patched PPTX to the user
  4. User opens patched file in PowerPoint and exports to PDF -- fonts now embed correctly

Note

PDF export must be done from PowerPoint desktop. Server-side converters (LibreOffice, Graph API) do not reproduce the same font embedding behavior.
