Share Guide
Share mind maps via URL
Overview
Share any mind map with a single URL. No server upload or account required. The recipient opens the link and sees the mind map immediately.
How It Works
Click the Share button in the toolbar. TextMapIt compresses your markdown content using LZ-string encoding and embeds it in the URL hash fragment. The share URL is copied to your clipboard automatically.
URL Structure
The share URL format: https://textmapit.com/markmap#<compressed_data>. The hash fragment contains the LZ-string compressed base64-encoded markdown. The compression is reversible — anyone with the URL can decompress and view the full content.
Opening a Shared Link
Recipients simply open the URL in any browser. TextMapIt detects the hash fragment, decompresses the data, and loads the mind map. No account, no installation, no sign-up needed.
Limitations
URLs have practical length limits. If compressed content exceeds approximately 4000 characters, sharing is disabled with a "Content too large for URL sharing" message. To reduce size, simplify your markdown or remove unnecessary detail.
Privacy
Shared URLs contain the full markdown content encoded in the URL. Anyone with the URL can decode and read it. Do not share URLs containing sensitive or private information.
