CapoChart is a free web app that transposes the chord charts you already have. Upload a PDF, scan, or photo of a chart, pick a target key or capo position, and CapoChart finds each chord symbol and rewrites it in place. Lyrics, staff notation, tablature, and the page layout stay as printed. Compare the original and transposed pages side by side, correct any chord it missed, and download a print-ready PDF.
For every key, CapoChart ranks the capo positions by how many chords become easy open shapes instead of barre chords, so you can choose the most comfortable way to play a song without changing how it sounds. The transposed chart gets a "Capo 5 for G" header, so everyone knows what to play.
The site also includes a standalone capo calculator that works from a key or a list of chords, a capo chart that shows what every open shape sounds like at every fret, a chord library with diagrams in all 12 keys, chords-in-every-key reference pages, key-to-key transposition tables, and plain-English guides.
No account or sign-up is required. CapoChart runs in any modern browser on phone, tablet, and desktop, and accepts PDF, PNG, JPG, and TIFF files.
