Upload a PDF or photo of a chord chart and every chord symbol is re-stamped in the new key, in place — the printed layout, lyrics and spacing stay exactly as they were. Every other free transposer wants chords pasted in as text. CapoChart reads the chart you already have, including scans and phone photos, and hands back a print-ready PDF. Plus a capo calculator and chord diagrams in all 12 keys. Everything runs without an account.
