🚔 DeckMedic · Repair Shop Suite · Tool 2 of 3
Helvetica doesn't exist on Windows. Futura isn't bundled with Office. Gotham requires a commercial license most machines don't have. Design agencies building brand decks on macOS send beautiful files to clients — who open them on Windows and see mangled layouts, overflowing text boxes, and broken grids. Font Police finds every non-standard font across slides, masters, and theme files, and replaces it with the nearest Windows-safe equivalent before you send.

Scan all XML font declarations
Reads every typeface="..." attribute across slides, layouts, masters, notes masters, and theme files — capturing fonts declared at every level of the presentation hierarchy.
Match against known-unsafe list
Each font name is checked against a curated map of 20+ Mac-only and commercial fonts. Known problematic fonts are auto-replaced. Theme font references (+mj-lt, +mn-lt) are always preserved. Unknown fonts not in the safe list are flagged for manual review.
Download with audit report
The Before→After replacement table shows every font changed and how many times. Unknown fonts are listed separately so you can decide whether to keep or manually replace them.

Enterprise IT & Template Owners
Auditing company-wide deck templates to enforce Windows-safe font standards? Font Police flags every non-compliant font instantly.
No. Helvetica is bundled with macOS, not Windows. Windows users see Arial instead — which appears visually similar but has different metrics. Letter-spacing differences can push text out of boxes on complex slides.
Fonts bundled with Windows 10/11: Arial, Calibri, Cambria, Century Gothic, Georgia, Impact, Segoe UI, Tahoma, Times New Roman, Trebuchet MS, Verdana. Office installs add: Aptos (Office 2024+), Candara, Consolas, Constantia, Corbel.
Yes. The tool scans all typeface declarations in slide content, slide layouts, slide masters, notes masters, and theme files — every layer of the inheritance chain.
Unknown fonts (not in the known-unsafe list) are flagged for review but never auto-replaced. For known-unsafe fonts that you want to keep, you can skip downloading the output file.
