Best Free PGN Viewers Online — Compared
A PGN viewer lets you replay any chess game move by move in your browser — no board, no pieces, just paste the PGN text and go. You need one when you want to study a game from a book or database, replay a game you just played, or follow along with annotated tournament games.
The problem: most PGN viewers either require an account, hide features behind a paywall, or make you download software. This guide compares the best free options available right now, with no signup and no install required.
What is a PGN file?
PGN stands for Portable Game Notation — the universal format for recording chess games as text. A PGN file looks like this:
[Event "Opera Game"] [Date "1858"] [White "Paul Morphy"] [Black "Duke of Brunswick"] [Result "1-0"] 1. e4 e5 2. Nf3 d6 3. d4 Bg4 4. dxe5 Bxf3 5. Qxf3 dxe5 6. Bc4 Nf6 7. Qb3 Qe7 8. Nc3 ...
Every chess database, game export, and opening book uses PGN. A good PGN viewer parses this text and lets you replay the game on an interactive board.

Detailed Reviews
#1 — Best Overall
Chess.lc PGN Viewer
The chess.lc PGN viewer is the fastest way to replay a game online. Paste any PGN text and the board loads instantly. Navigate moves with the on-screen buttons or keyboard arrow keys. Press F to flip the board. The default game loaded is Morphy's Opera Game (1858) so you can test it immediately without pasting anything.
- Parses PGN headers, comments, variations, and NAG annotations
- One-click Stockfish analysis — sends the current position directly to chess.rodeo
- Copy FEN of any position, keyboard navigation, first/last jump buttons
- Zero account, zero paywall, works on mobile
#2 — Best Runner-Up
Lichess Analysis Board
Lichess is the best open-source chess platform available, and its analysis board is genuinely excellent. It includes a built-in Stockfish engine that runs in the browser, opening name detection, move arrows, and computer evaluation graphs. The downside: importing a PGN requires going through the game import flow rather than a simple paste, which adds friction. The UI is also heavier and slower to load than simpler viewers.
Best for: players who want built-in engine analysis without leaving Lichess. Not ideal for: quickly replaying a single game from a text paste.
#3 — Paywalled Analysis
Chess.com Game Analysis
Chess.com's game analysis tool requires an account and paywalls Stockfish analysis behind their Diamond subscription ($29/month or $119/year). Free users get a basic move accuracy score but no engine lines, no alternative move suggestions, and limited analysis slots per day. If you want real Stockfish depth, you are paying for it on Chess.com.
Best for: Chess.com subscribers who already pay. For everyone else: use chess.lc's PGN viewer and jump to chess.rodeo for free engine analysis.
What to Look for in a PGN Viewer
No account required
You shouldn't need to register to view your own games. Any viewer that forces signup before loading a PGN is adding friction with no benefit to you.
Supports variations
Annotated games often contain alternative move lines (variations). A good viewer lets you explore these branches, not just the main line.
PGN comment display
Grandmaster-annotated PGN files include text comments explaining moves. A viewer that strips these is throwing away the most valuable part of the game.
Engine analysis access
The best viewers let you jump from any position directly to Stockfish analysis. You shouldn't have to manually copy FEN strings to a separate tool.
Keyboard navigation
Arrow keys for next/prev move are standard. A viewer that requires clicking for every move is frustrating to use for a 50-move game.
Mobile-friendly board
If you're replaying games on your phone, the board needs to scale properly and tap targets need to be large enough to navigate easily.
How to Use a PGN Viewer for Game Analysis
The standard workflow for reviewing a game: export PGN → view moves → identify the moment you went wrong → analyze that position with an engine. Here's how to do all of this for free:
- Export your game as PGN. On Lichess: game page → Share → Download PGN. On Chess.com: Archive → select game → Export. You'll get a text block with headers and moves.
- Paste PGN into the viewer. Go to the chess.lc PGN viewer, paste your PGN text into the input box, and click Load Game. The board loads immediately.
- Replay the game, find the mistake. Use arrow keys to step through moves. Look for the moment the evaluation shifted — that's usually where the game was decided.
- Analyze with Stockfish, free. At any position, click "Analyze with Stockfish" to open that exact FEN in chess.rodeo. Full Stockfish analysis — no account, no paywall. See the engine's top candidate moves and understand what you missed.
- Note the pattern, practice it. Once you find a tactical pattern you missed, go practice it on the tactics pages to build pattern recognition for next time.
Analyze any chess position for free
Load a PGN on chess.lc, then send any position directly to Stockfish on chess.rodeo. Full engine analysis — no account, no paywall, no time limit.
