Features

Drag & Drop Image Insertion

Drop an image into the text area and Base64-encoded image data is inserted at the cursor position. File picker and clipboard paste are also supported.

No Paths, No Broken Links

Image data is stored directly inside the Markdown file, so there is no need to manage relative or absolute paths. Moving folders will never break your images.

Live Markdown Preview

Changes are reflected in the preview pane in real time, so you can check image rendering and overall layout as you type.

Runs Entirely in the Browser

From image loading to Base64 conversion, every step happens locally in your browser. No data is sent to any server, making it safe for confidential specs and internal manuals.

Ideal For

Manage Image-Rich Docs in a Single File

End Broken Image Links for Good

Eliminate path-related link breakage at its root. Images always display regardless of the PC or folder structure.

Create Manuals for Offline Viewing

With images embedded as Base64 inside the file, documents display correctly even without an internet connection.

FAQ
Which image formats are supported?
JPEG, PNG, GIF, WebP, and other common formats that modern browsers can display are supported.
Are images saved on the server?
No. All processing, including image loading and Base64 conversion, is completed within the browser. No data is sent externally.
What is the difference between Base64 embedding and image path references?
Path references (relative, absolute, or URL) require separate image file management and can break when files are moved. Base64 embedding stores image data directly inside the Markdown file, keeping everything in one place with no risk of broken links.
How does Base64 affect the file size?
Converting image data to a text string increases the data volume by roughly 33% compared to the original file. If you embed many large images, consider resizing them beforehand to keep the file manageable.
Can I change the display size of an embedded image?
Standard Markdown syntax does not support image sizing, but you can switch to an HTML img tag (e.g., <img src="data:..." width="300">) to control width and height freely.
