Paste or Drop Images into Markdown — Split View, Cursor Position, and Limits
Insert images into Markdown by paste (Ctrl+V / Cmd+V) or drag-and-drop in Split view. Supported formats (PNG/JPEG/GIF/WebP), 5 MB limit, base64 embedding, troubleshooting, and privacy.
What you’ll learn
- How to paste an image (Ctrl+V / Cmd+V) into the editor
- How to drop an image file onto the editor pane
- Which view mode you need (preview-only won’t show the editor)
- Supported formats and size limits
- Where the line is inserted (cursor) and how HTML download embeds images
Use this when you want screenshots or captures in Markdown without saving an image file first.
Use Split view first
Paste and drop work when the Markdown editor (textarea) is visible on the left.
In the toolbar, switch to Split so you see editor on the left and preview on the right. If you only use Preview, there is no editor—switch to Split before pasting or dropping.
(You can also align the URL with ?view=split.)
1. Paste from the clipboard
- Click the editor and place the cursor where you want the image.
- Copy an image (screenshot, copy from browser, etc.).
- Ctrl+V (Windows) or Cmd+V (Mac).
A Markdown image line is inserted at the cursor. The default alt text is 「画像」 (you can edit the  part afterward).
2. Drag and drop a file
- Place the cursor where you want the image.
- Drag an image file from your file manager onto the left editor pane.
- Drop.
If multiple files are selected, only the first is inserted (by design). Drop again or paste for additional images.
Supported formats and size
Supported MIME types:
- PNG (
image/png) - JPEG (
image/jpeg,.jpg) - GIF (
image/gif) - WebP (
image/webp)
Maximum size per file: 5 MB.
What gets inserted
The tool inserts standard Markdown image syntax with a Data URL (base64):
Preview and PDF render it like any image. Download HTML inlines styles and embeds images as Base64 so you can distribute one self-contained HTML file.
Troubleshooting
| Issue | Check |
|---|---|
| Nothing pasted | Are you in Split view? Preview-only has no editor. |
| Drop does nothing | Drop on the left editor; dropping on the right preview may trigger .md loading instead. |
| Not an image | Plain text paste may behave differently. |
| Too large | Keep files under 5 MB. |
