I am planning to create a chess puzzle book for beginners. Diagrams need to be published in the book. Right now I have all the materials in PDF. But I need a software to create diagrams for a particular chess position. Is there any way to scan chess diagrams from a PDF?

    What format should the diagrams be in? Postscript or something else? – Scounged Jun 5 '16 at 12:01

    Please answer Scounged's comment. Your question is very unclear: you have diagrams in your PDF and you want to create diagrams ??? – user4378 Aug 25 '16 at 11:11

I wrote a program that can recognize positions from books and magazines and give you the FEN. Here is the web interface for Chessputzer

You can upload the image or paste directly from the clipboard.

Note: it is designed for the the most common fonts used in print. It won't work for images from Chessbase etc. For that, use Fenbot.

My aim was to make it good enough to read blurry images from old chess books so it should be pretty tolerant of artifacts and such.

Try the following. You upload the image, it scans and generates FEN. I don't know if it will read a pdf but converting a pdf to a common graphic format is not hard.

Chess Grabber

I tried it using the diagram from this posting. It generated its determination of the diagram and this FEN:

rn1qk1nr/Pp4P1/2p2P2/4P2p/1bp5/2NbPPP1/PP2N1BP/B1BQ1RK1 w kq - 0 1

  • I tried it and it took black pawns on dark squares to be white pawns. So it is not perfect. One has to be careful. – DrCapablasker Jun 5 '16 at 17:32
  • Chess Grabber seems to be buggy. – Arun J Jun 3 '19 at 7:17
  • Chess Grabber doesn't work if Adobe Flash is blocked ... I think Flash is basically deprecated now. Maybe archive.org can support it? – Purplejacket Dec 5 '20 at 17:23

This website has a chess ebook reader available for scanning chess diagrams from PDF: https://chessvision.ai/

Additionally they also have browser extensions for Chrome and Firefox which is really handy in scanning images of positions on any web page.

Chessfimee can perfectly serve you.

It scans and analyses chessboards with chess diagrams, puzzles. All you need is to use the camera to take a photo of a chess diagram from books, papers, even LCD screens (PDFs, other sources). Also you can share the chess position (FEN) with other chess applications.

An iOS version will be coming soon.

  • This is the right way to do it, I think. Fewer mishaps. – friscodelrosario Sep 7 '20 at 6:20

There's also ChessOCR, which I found useless, but as we always say, your mileage may vary.
