Heads-up
If your vault is private and you'd rather not put screenshots on a public URL, stick with embedded attachments. swiftimg is best for notes you eventually publish.
Step by step
1. Upload the screenshot
Drop it at /upload, or use the swiftimg CLI to upload from a script or hotkey.
CLI swiftimg upload screenshot.png2. Paste the Markdown into your note
Use the standard Markdown image syntax — Obsidian inlines it like any image embed.
Markdown 3. Publish without surprises
When you publish notes (Obsidian Publish, a static site, or pasting elsewhere), the same Markdown keeps working — no broken vault-relative paths.
Obsidian — FAQ
Doesn't Obsidian already handle attachments?
It does — by stashing files in the vault. That's great for fully offline use, but inflates sync size and breaks when you copy notes outside the vault. External hosting is the trade-off.
Can I automate the upload from a hotkey?
Yes — the @swiftimg/cli package gives you `swiftimg upload <file>` that prints the URL, so an Alfred / Raycast / shell hotkey can upload and copy in one step.
Will the images load offline?
No — externally-hosted images need a network. For fully offline notes, keep attachments in the vault.
