Telegram message formatter
Format text for Telegram channels with bold, italic, monospace, and links (HTML/Markdown modes).
about the telegram message formatter
Telegram supports rich text — bold, italic, underline, strikethrough, spoilers, monospace code, and inline links — but getting it right depends on which parse mode you're using. Bots and the API accept two syntaxes, MarkdownV2 and HTML, and each has its own escaping rules; a single unescaped character in MarkdownV2 can make the entire message fail to send.
The practical limits matter too: a Telegram text message can be up to 4,096 characters, while media captions are capped at 1,024. In MarkdownV2 you write *bold* and _italic_ but must escape characters like . ! - ( ) with backslashes; in HTML you use <b> and <i> tags with no escaping headaches, which is why many channel admins prefer HTML mode for anything non-trivial.
Write your message in the formatter, apply bold, italic, monospace, and links visually, and copy out clean MarkdownV2 or HTML that Telegram will accept on the first try. Then drop the finished message into PostAI's scheduler to post to your channel at a consistent time without keeping Telegram open.
frequently asked questions
How do I make text bold or italic in Telegram?
In the app, select text and use the formatting menu, or type *bold* and _italic_ syntax. Via bots and the API, send the message with parse_mode set to MarkdownV2 (*bold*, _italic_) or HTML (<b>bold</b>, <i>italic</i>). HTML mode avoids MarkdownV2's strict character-escaping rules.
What is the Telegram message character limit?
Text messages can be up to 4,096 characters. Captions on photos, videos, and other media are limited to 1,024 characters. Longer content needs to be split across multiple messages.
Why does my Telegram bot message fail with a parse error?
Almost always unescaped special characters in MarkdownV2 mode. Characters like . ! - ( ) # + = must be escaped with a backslash or Telegram rejects the whole message. Switching to HTML parse mode, or using a formatter that escapes automatically, fixes it.
