Best Free PGN Viewer Apps for Windows, Mac, and MobilePortable Game Notation (PGN) is the standard plain-text format for recording chess games. A good PGN viewer makes it easy to load, replay, annotate, and share games — whether you’re studying openings, following grandmaster practice, or saving your own tournament games. This article surveys the best free PGN viewer apps across Windows, macOS, and mobile platforms, highlights their strengths and weaknesses, and offers tips for choosing the right one for your needs.
What to look for in a PGN viewer
A useful PGN viewer should offer several core capabilities:
- Load and save PGN files (single games and multi-game collections).
- Accurate move display and board replay, including variations and move annotations.
- Navigation controls (jump to start/end, step forward/back, move list).
- Support for comments, NAGs, and standard PGN tags (Event, Site, Date, White, Black, Result).
- Copy/paste FEN and export positions for analysis.
- Optional but valuable: engine integration, graphical opening explorer, cloud sync, and sharing.

Tips for using PGN viewers effectively
- Keep your PGN files organized by event/date and use consistent tagging in the PGN headers.
- Convert large PGN collections into a searchable database (Scid) for fast retrieval.
- Use engine analysis sparingly when studying; focus first on human-intelligible ideas, then confirm with the engine.
- Export critical positions as FEN when you want to import a single position into other tools.
