Telegram History Downloader

Export chat, group and channel history from Telegram Web (WebK) to JSON, HTML and Markdown.

Save the history of any Telegram chat, group or channel from Telegram Web to a file in a couple of clicks, right in your browser. Export to HTML, JSON and Markdown, with or without photos, videos, voice messages and files. Open a chat at web.telegram.org/k/, click the extension icon, choose what to save and hit Download. The file or ZIP archive lands in your Downloads folder. WHAT YOU CAN EXPORT • Private chats, bots, groups, channels and Saved Messages. • The entire history, the latest N messages, or messages from a date range. • Formatted text and links, reactions, views, polls, locations, contacts, link previews and service messages. FORMATS • HTML — a readable copy of the conversation that opens in any browser, offline. • JSON — structured data for analysis, search and import into other tools. • Markdown — plain text for notes, Obsidian, Notion and knowledge bases. Pick several formats at once. MEDIA • Photos, videos and GIFs, voice and audio, files, stickers — download only what you need. • A file size limit to skip large videos. • Messages and media are packed into one ZIP archive with links to the files. CONVENIENT • Runs in the background: close the popup and the export keeps going while the Telegram tab stays open. • Live progress, message and media counters, and a Stop button. • English and Russian interface, light and dark theme. PRIVACY • Everything runs locally in your browser through your existing Telegram Web session. • The extension doesn't send messages, files or account data to any third-party server, has no analytics and needs no separate login. • It only requests access to web.telegram.org. GREAT FOR • Backing up important conversations. • Archiving a work chat or channel before it's deleted. • Exporting chat history for analysis, search or research. • Moving notes and materials from Saved Messages to your knowledge base. LIMITATIONS • Works with Telegram Web K (web.telegram.org/k/). The /a/ version isn't supported. • The extension relies on Telegram Web internals and may temporarily stop working after Telegram Web updates. • Large archives with media are built in browser memory — for big channels, limit the date range and file size.
