Free chess tools

Free chess notation converter

Convert between chess notation formats — PGN, FEN, SAN, UCI. Free, instant, and entirely in your browser.

Convert a PGN game to the FEN of any position, wrap a FEN position into a valid PGN file, or translate move lists between SAN (e4, Nf3) and UCI (e2e4, g1f3) notation.

Every conversion shows a live board preview of the resulting position, so you can verify the output at a glance.

Looking to turn a game into a video instead? That's our specialty — the chess.video generator turns any PGN into an animated video for free.
