Best Practices for Using Images in Markdown

Best Practices for Using Images in Markdown

Treat Markdown images as part of the story

Markdown makes it easy to drop screenshots or diagrams into docs, but once those images travel to social or slide decks the weak spots show up. Build a repeatable checklist so every asset has the same quality bar.

Write alt text before exporting

  • Summarize the value of the graphic, not the color palette.
  • Keep it under 140 characters and avoid phrases like “image of…”.
  • Mention key numbers or outcomes so readers who load text-only emails still understand the point.

Host once, reuse everywhere

  1. Compress the source file with TinyPNG/ImageOptim or export directly from Markdown2Image at 2×.
  2. Upload to Directus, S3, or the Markdown2Image CDN and copy the canonical URL.
  3. Track each asset (file name, alt text, publish date) in a shared sheet so marketing and docs stay aligned.

Finish inside Markdown2Image

  1. Paste the Markdown snippet and pick an aspect ratio: Thread, Deck, or Mobile.
  2. Choose a preset, then adjust typography, spacing, and accent colors to match your brand.
  3. Export PNG/SVG/WebP and grab the embed code for README files or CMS blocks.
## Image handling upgrades
- Drag-and-drop uploader accepts SVG
- Automatic alt-text reminders
- Asset URLs stay stable across locales

Publishing cues

  • Share the PNG directly on Twitter/LinkedIn with a link back to the full article.
  • Drop the SVG into slides when you need crisp edges on large screens.
  • Include descriptive captions when sending newsletters so the visual is anchored in context.

Markdown stays clean, the exported image looks like a designer touched it, and you only manage one canonical file.
