Frequently Asked Questions
Click any fret position to place a finger dot, drag across strings to create a barre chord, click open string indicators to mark them as open or muted, then export your diagram as PNG, JPG, or SVG.
Click a dot that is already on the fretboard and its number cycles 1 → 2 → 3 → 4, then removes the dot on the next click. New dots are numbered for you automatically, so this is how you write a fingering the tool did not guess — a G shape fingered 2-3-4 instead of 1-2-3, for example. Clicking a barre bar cycles the whole bar's number the same way.
Yes. Use the Load from Library panel to search for a chord (like Am7 or Gsus4) or browse by difficulty, then click it to auto-fill the fretboard — finger dots, open and muted strings, and barre chords are placed for you. From there you can edit any dot to create your own variation before exporting.
Yes. To create a barre chord diagram, drag across the strings at the desired fret. The tool will automatically draw a barre chord bar across all the strings you drag over.
You can export your chord diagram as PNG, JPG, or SVG. PNG and JPG are best for embedding in documents and presentations. SVG is best for use in web design or when you need a scalable vector format.
Yes. Click Preview Output on the export card to see exactly how your diagram will look — including the selected background — before you download. The preview matches the exported file precisely.
Yes. Choose the None (transparent) background to export a PNG or SVG with no background, ideal for overlaying on slides, websites, or colored pages. For transparent exports you can pick dark ink for light backgrounds or light ink for dark backgrounds, so the diagram stays readable wherever you place it.
Yes — it works as both a chord diagram generator and a chord diagram maker. Pick a chord name in the Load from Library panel (like Am7 or Gsus4) and it generates the diagram automatically, or build a shape from scratch by placing each finger dot yourself. Generate in one click, then customize.
