Chord Diagram Generator

Create chord diagrams for guitar, ukulele, and bass. Choose from chord library or build custom fingerings. Export as PNG or SVG.

Generate clean fretboard chord diagrams for guitar, ukulele, and bass. Pick an instrument and a chord from the built-in library, or build your own fingering by clicking directly on the fretboard, then export the diagram as a high-resolution PNG or a scalable SVG. Each diagram shows finger-position dots, open (O) and muted (X) string markers, barre bars where needed, optional finger numbers, and the instrument tuning along the bottom. This is a musical chord-chart tool, not a data-visualization chord diagram.

Chord Diagram Generator: a worked example

You are writing guitar tab and need a clean G-major chord diagram to embed in a lesson PDF.

Input

Guitar · G major · fingering 3-2-0-0-0-3
Chord Diagram Generator produces

Output

An SVG fretboard diagram with dots, finger numbers, and open/muted markers

The diagram renders strings, frets, and finger positions to standard notation conventions, exported as crisp SVG for print. It removes the tedium of drawing fretboards by hand for teaching material.

What is the Chord Diagram Generator?

Generate clean fretboard chord diagrams for guitar, ukulele, and bass. Pick an instrument and a chord from the built-in library, or build your own fingering by clicking directly on the fretboard, then export the diagram as a high-resolution PNG or a scalable SVG. Each diagram shows finger-position dots, open (O) and muted (X) string markers, barre bars where needed, optional finger numbers, and the instrument tuning along the bottom. This is a musical chord-chart tool, not a data-visualization chord diagram.

How to use

  1. 1Choose an instrument: guitar, ukulele, or bass
  2. 2Pick a chord from the library, or click the fretboard to build a custom fingering
  3. 3Toggle finger numbers, tuning labels, and an accent color scheme
  4. 4Download as PNG (3x scale) or SVG, or copy the SVG markup

Where this helps

  • Teaching materials

    Add clear chord charts to lesson sheets, songbooks, and beginner guides for guitar, ukulele, or bass.

  • Songwriting and tabs

    Document the exact fingerings used in a progression so others can play it the same way.

  • Custom chord shapes

    Build and export an unusual or higher-neck fingering that is not in the standard library.

  • Web and print embedding

    Drop the SVG into a website or scale it up for print without any loss of sharpness.

Key features

  • Guitar, ukulele, and bass fretboard diagrams
  • Built-in library of common major, minor, and 7th chords (plus bass power chords)
  • Click-to-build custom fingerings with open/muted string toggles
  • Automatic barre-bar rendering and starting-fret indicator for higher shapes
  • Optional finger-number overlay and tuning labels
  • Five accent color schemes
  • Export as high-resolution PNG (3x) or scalable SVG, or copy SVG markup

How It Works

The diagram is drawn as an SVG fretboard sized to the selected instrument: 6 strings tuned E A D G B E for guitar, 4 strings tuned G C E A for ukulele, and 4 strings tuned E A D G for bass, each showing a 5-fret window. The built-in library covers common open and barre shapes - major, minor, and 7th chords for guitar (C, D, E, F, G, A, B and their minor and 7th variants), a starter set of ukulele shapes, and bass root-position and power-chord patterns. Barre chords automatically render a rounded bar across the spanned strings, and shapes that sit higher up the neck (like B or Gm) show a starting-fret indicator instead of the nut. You can also type a custom chord name and click cells on the fretboard to place fingers, with the top row toggling each string between open and muted.

Export runs entirely in the browser. SVG export serializes the live diagram so it stays crisp at any size and can be edited in Illustrator, Inkscape, or Figma. PNG export rasterizes the SVG onto a canvas at 3x scale over a dark background for a sharp bitmap. You can also copy the raw SVG markup to the clipboard. Display options let you toggle finger numbers and tuning labels and pick from five accent color schemes (blue, green, purple, orange, red).

Frequently asked questions

Which instruments are supported?

Guitar (6 strings, standard EADGBE tuning), ukulele (GCEA), and bass (EADG). Each diagram shows a 5-fret window with the correct string count and tuning.

Can I make my own chord shapes?

Yes. Type a chord name and click cells on the fretboard to place fingers. Clicking the top row toggles each string between open and muted.

Can I export as vector graphics?

Yes. SVG export gives you a scalable vector version you can edit in Illustrator, Inkscape, or Figma. You can also export a 3x PNG or copy the raw SVG markup.

Does it show finger numbers and tuning?

Both are optional toggles. Turn on finger numbers to label which finger plays each note, and tuning labels to show the open-string notes along the bottom.
