Telegram post preview

See a channel post the way subscribers will: the bubble, the link card, the photo caption, and the limit you are about to hit.

Your post

240 / 4,096

A text message holds 4,096 characters. Add a photo and the text becomes a caption, which holds 1,024.

What the preview shows

The same Telegram renderer Postacio’s composer uses: the channel’s message bubble with its photo, the link card Telegram builds from your first link, and the view from a phone or a desktop.

The card comes from the page’s own tags, the way Telegram reads them: the site name, the title, two lines of description and the image, drawn large when the image is wide enough and as a square beside the text when it is not.

Telegram limits that cut posts short

  • 4,096 characters in a text message.
  • 1,024 characters in a caption, once the post carries a photo, video or file.
  • 10 photos or videos in one album.
  • 12 options in a poll.

Formatting Telegram supports

Bold, italic, underline, strikethrough, inline code and links, plus custom emoji. Line breaks are kept exactly as you type them.

Formatting does not change the count: the limit is measured on the words, not the markup.

Questions before you start.

Why does my Telegram caption get cut off?

A photo or video caption holds 1,024 characters, a quarter of what a text message holds. Bots, and so every scheduler that posts through one, are held to that limit. Postacio sends the rest as its own message right after the photo, so nothing is lost.

What is the difference between the message limit and the caption limit?

A text message holds up to 4,096 characters. As soon as the post carries a photo, video or file, the text becomes a caption, and a caption holds 1,024. Add a photo above and watch the limit change.

Does Telegram show a link preview for every URL?

Telegram draws a card for the first link in a message when that page offers a title, a description or an image, usually from its Open Graph tags. A page that offers none gets no card, or just its address. The preview above fetches the same tags Telegram reads.

Which formatting does Telegram support?

Bold, italic, underline, strikethrough, inline code and links, plus custom emoji for channels that have them. Postacio's composer writes all of these and sends them as Telegram's own formatting.

Can I schedule a Telegram channel post?

Yes. In Postacio you connect a channel or group through a bot you create with @BotFather, then write the post, pick a time, and it goes out on its own with its photos, formatting and link card. See the Telegram scheduler page for how it works.

Is my photo uploaded?

No. The photo is shown from your own browser and never leaves it. The only thing the page asks our server for is the link card, and only for the address of the link.
