How to Export Guitar Chord Diagrams as Images for Lessons, Charts, and Social Media

You've found the perfect voicing for that Cmaj7#11. Now you need to put it in a lesson plan, a chord chart, or a social media post so someone else can see it. A text description ("third fret, barre the top four strings, add your pinky on the seventh fret of the high E") doesn't cut it. You need a visual.

Export formats and when to use each

PNG — raster image. Fixed resolution. Best for: social media posts, lesson handouts, quick sharing. Choose a resolution that matches your use case: 300 DPI for print, 72-150 DPI for screen. Higher resolution = larger file, sharper print.

PDF — vector or embedded raster. Scalable without quality loss (if the diagram is rendered as vector). Best for: lesson plans, chord books, anything that will be printed. PDF preserves layout and can combine multiple diagrams on one page.

SVG — pure vector. Infinitely scalable. Best for: websites, apps, any digital display where you need the diagram to render sharply at any size. Also editable in vector graphics software (Illustrator, Inkscape).

Markdown — text-based chord diagram. Useful for embedding in documentation, README files, or any plain-text context. Limited visual quality but works everywhere.

What makes a chord diagram readable

A good chord diagram tells you five things at a glance:

1. Which frets to press — dots or circles on the relevant strings and frets
2. Which finger to use — numbers inside the dots (1=index, 2=middle, 3=ring, 4=pinky)
3. Which strings to mute — an X above the string
4. Which strings to play open — an O above the string
5. Where on the neck you are — fret number on the left side of the diagram, or a clear indication that the top line of the diagram is the nut

If any of these are missing or ambiguous, the diagram confuses more than it helps.

Common export mistakes

Omitting the fret number — a diagram without a fret position indicator is useless. Is that Cmaj7 at fret 3 or fret 8? The shape looks the same.

Low-resolution PNG for print — a 72 DPI screenshot looks acceptable on screen but prints as a blurry mess. Always export at print resolution if there's any chance the diagram will be printed.

Default diagrams without finger numbers — dots without finger numbers force the reader to guess which finger goes where. One ambiguous diagram wastes practice time as the student tries three different fingerings before finding the right one.

Exporting every possible voicing — a page with 24 voicings for one chord is overwhelming, not helpful. Export the 2-4 voicings that are actually relevant to the lesson or chart.
