Export as Base64 MD

Export the active note as a single, self-contained markdown file with every image embed inlined as a base64 data URI one command, one native save dialog, done.

Features

• Resolves every image embed in the note (![[image.png]] and ![alt](image.png) syntax) via Obsidian's metadata cache
• Inlines each one as a data:image/<type>;base64,... URI in place of the embed
• Native OS "Save As" dialog, defaults filename to the note's title
• Vault note is never modified only the exported copy is written
• Supports png, jpg/jpeg, gif, webp, bmp, svg

Why I built this

I use Obsidian mostly to prepare writeups for the machines and challenges I solve. I publish these writeups on my website, which uses a 𝗠𝗼𝗻𝗴𝗼𝗗𝗕-𝗯𝗮𝗰𝗸𝗲𝗱 𝗖𝗠𝗦 for storage. Storing images directly in 𝗠𝗼𝗻𝗴𝗼𝗗𝗕 requires a lot of space, and a few images are enough to blow past a 500MB tier.

Therefore, I designed my website to intercept base64 data URIs in uploaded markdown in a public GitHub repo and rewrite the links to a 𝗷𝘀𝗗𝗲𝗹𝗶𝘃𝗿 𝗖𝗗𝗡 𝗨𝗥𝗟 before the markdown ever touches the database.

The missing piece was getting from "writeup with normal image embeds in Obsidian" to "one flat markdown file with base64 inlined" without doing it by hand. So I built a plugin for it. Hope its useful for y'all.

Installation

From Community Plugins

Settings → Community Plugins → Browse → search "Export as Base64 MD" → Install → Enable.

Manual / BRAT

1. Install the BRAT plugin.
2. Command palette → BRAT: Add a beta plugin for testing.
3. Paste this repo's URL.
4. Enable "Export as Base64 MD" under Installed Plugins.

Usage

1. Open the writeup you want to export.
2. Run Export active note from the command palette (Ctrl/Cmd+P). Want a hotkey? Bind one yourself in Settings → Hotkeys. the plugin doesn't ship a default, so it won't conflict with anything you've already set.
3. Select a destination in the native save dialog.
4. A flat .md file with all images inlined lands where you choose.

Notes

• Desktop only uses @electron/remote and Node's fs, unavailable on mobile.
• Broken/unresolvable embeds are left as-is rather than failing the whole export.
