Guitar Chord Diagram Generator – Create & Export Free

Create Professional Guitar Chord Diagrams in Minutes

A guitar chord diagram generator lets you design custom chord charts for practice, teaching, songwriting, and publishing. Whether you’re documenting an original voicing, creating lesson materials, or adding chord diagrams to a music blog, this tool provides an easy way to build clean, high-quality diagrams directly in your browser.

Unlike basic chord chart makers that only support standard open chords, this Guitar Chord Diagram Generator allows you to customize every string, create barre chords, change tunings, preview the chord with realistic synthesized audio, and export your finished diagram as a scalable SVG or high-resolution PNG. Everything is processed locally in your browser, so your work remains private and no information is uploaded to an external server.

How to Use the Guitar Chord Diagram Generator

Creating a custom guitar chord diagram is simple:

1. Enter a Chord Title and an optional subtitle.
2. Select the fret position for each of the six strings, choosing whether a string is muted, open, or fretted.
3. Assign finger numbers (1–4) or use T for thumb fingerings where appropriate.
4. Add a barre chord by selecting the fret and the strings it spans.
5. Choose the base fret, number of frets to display, and your preferred tuning.
6. Customize the appearance using one of the available color themes.
7. Preview the finished diagram and listen using Strum Down, Strum Up, or Arpeggiate.
8. Export the finished chord diagram as SVG, PNG, ASCII text, or an HTML embed snippet.

If you’re new to reading guitar chord charts, our guide on How to Read a Guitar Chord Diagram explains every symbol you’ll see on the generated diagram.

Customize Every Part of the Chord Diagram

The generator gives you complete control over how your chord is displayed.

Each string can be configured individually, allowing you to specify muted strings, open strings, or any fret position up to the supported range. Finger assignments can also be added to make the diagram easier for students or readers to follow.

If your chord uses a barre, the built-in barre configuration lets you define both the fret and the string span, producing a clean visual arch across the selected strings.

This flexibility makes the tool suitable for documenting everything from beginner open chords to advanced jazz voicings and custom arrangements.

Support for Alternate Tunings

Many songs use alternate tunings that change the pitch of the open strings. Instead of manually recalculating every note, the Guitar Chord Diagram Generator automatically adjusts the displayed information for the selected tuning.

Supported tunings include:

• Standard E A D G B E
• Drop D
• Half Step Down
• Full Step Down
• Open D
• Open G
• DADGAD

This makes the tool useful for acoustic guitarists, fingerstyle players, songwriters, and musicians who frequently experiment with alternate tunings.

Preview the Chord with Built-In Audio

Visual diagrams show where to place your fingers, but hearing the chord provides another level of confidence before you save or share it.

The built-in audio player uses real-time Web Audio synthesis to generate guitar-style playback directly inside your browser. You can choose between a downward strum, upward strum, or an arpeggiated performance to hear how the chord sounds.

This feature is especially useful when creating custom voicings, checking alternate tunings, or comparing similar chord shapes without switching to another application.

Export High-Quality Guitar Chord Diagrams

Once you’re satisfied with your design, the generator offers several export options for different workflows.

You can download:

• SVG for scalable, print-quality graphics.
• PNG for presentations, lesson sheets, and websites.
• ASCII diagrams for plain text documents.
• HTML Embed Code for quickly inserting diagrams into web pages.

Because SVG is vector-based, diagrams remain sharp at any size, making them suitable for educational materials, digital publications, and responsive websites.

If you’re looking for ready-made chord shapes instead of building your own, the Chord Dictionary provides a searchable collection of guitar chords.

Theory Information Included with Every Diagram

In addition to generating the visual chart, the tool analyzes your selected notes and displays useful musical information.

The results panel includes:

Information	Description
Detected Notes	Shows the notes contained in the diagram.
Bass Note	Identifies the lowest sounding note.
Harmony Match	Displays the closest matching chord name when available.
Muted Strings	Indicates which strings should not be played.

This analysis helps you verify that your custom fingering produces the chord you intended before exporting or sharing it.

Tips for Better Results

For the most accurate chord diagrams:

• Select the correct tuning before entering fret positions.
• Add barre information whenever a single finger covers multiple strings.
• Use meaningful chord titles and subtitles when creating teaching materials.
• Preview the audio before exporting your diagram.
• Choose SVG when you need scalable graphics for print or web publishing.
• Reset the diagram whenever you want to start a completely new design.
