ShareChess is a free, open-source web tool for generating animated chess videos from PGN input. Paste in a game in PGN notation and ShareChess renders it as a shareable animated GIF, MP4, or WebM file with customizable board themes, piece sets, move annotations, and frame timing.

The output is optimized for social media sharing — the square format works well on Twitter/X, Instagram, and Discord. Players use it to share memorable games, brilliant combinations, or instructional positions in a visually engaging format without needing video editing software.

ShareChess runs entirely in the browser with no server-side processing and requires no account or installation. It is the most convenient free option for creating chess video content from a PGN.
