Telegram Scraper & Chat Export: Members, Media, Video Downloader by Mastros

Description

Telegram scraper and chat export. Export group members, chats, contacts, messages & media to Excel, CSV, JSON. No API key. Scrape and export structured data from Telegram Web and download media in original quality, all client-side in your browser. No API key, no phone login, no setup — it works through the Telegram Web session you're already signed into. ━━━━━━━━━━━━━━━━━━━━━━━━ 🧩 FIVE SCRAPING MODES ━━━━━━━━━━━━━━━━━━━━━━━━ • Group Members — export a group or channel member list with names, @usernames, IDs and status. When the member list is locked, it gathers everyone who has posted instead (see below). • Chat Messages — export messages from any conversation with sender name, @username, timestamp and text. • Recent Contacts — export the people in your direct messages: real people only, with groups, channels and bots filtered out automatically. • Mutual Groups — find the groups you share with a given user, then extract any of them. • Media Downloader — download photos, videos, documents and voice notes from a chat in original quality. ━━━━━━━━━━━━━━━━━━━━━━━━ ⚡ NO SETUP, ONE ENGINE ━━━━━━━━━━━━━━━━━━━━━━━━ There is nothing to connect. No API ID, no API hash, no phone number, no verification code. Install it, open Telegram Web, and every mode works immediately using the session you're already logged into. Because it reads Telegram's own structured data instead of the text painted on screen, it returns @usernames that the interface never displays — and it behaves identically in every language Telegram ships in. ━━━━━━━━━━━━━━━━━━━━━━━━ 🔓 WHEN THE MEMBER LIST IS LOCKED ━━━━━━━━━━━━━━━━━━━━━━━━ Most large groups hide their member list from non-admins, which is where other tools stop and return only the handful of admins. Mastros tells you the list is locked, then gathers everyone who has actually posted in the chat — the people you can genuinely reach — and resolves their @usernames. Rows without a public username are still kept and flagged, so nothing is silently dropped. Broadcast channels where only the owner posts are detected up front and skipped, instead of being scanned pointlessly. ━━━━━━━━━━━━━━━━━━━━━━━━ 🛡️ BUILT TO RUN IN BURSTS ━━━━━━━━━━━━━━━━━━━━━━━━ Extraction is deliberately bounded: you choose how many messages a run reads, it pauses when it gets there, and asks before continuing. Sustained bulk activity is what puts a Telegram account at risk, so the tool is built to work in controlled bursts rather than one endless scan. ━━━━━━━━━━━━━━━━━━━━━━━━ 📦 EXPORT YOUR WAY ━━━━━━━━━━━━━━━━━━━━━━━━ • Excel / CSV: open directly in Excel, Google Sheets, or any spreadsheet tool. • JSON / JSONL: ready for scripts, pipelines and data tools. • Media: saved to your machine in original quality. Every run is saved as a session, so partial results are never lost — if a run stops early, the file is still there to download. ━━━━━━━━━━━━━━━━━━━━━━━━ 🔒 PRIVACY FIRST ━━━━━━━━━━━━━━━━━━━━━━━━ ✓ Read-only — no messages sent, no members added, no automation. ✓ Client-side — scraping and export happen in your browser; your data isn't shipped to us. ✓ You only ever access chats you're already a member of, and only data Telegram already shows your account. ✓ No credentials to store: there is no API key or password to hand over in the first place. ━━━━━━━━━━━━━━━━━━━━━━━━ 👤 WHO IS THIS FOR ━━━━━━━━━━━━━━━━━━━━━━━━ Growth, community and GTM teams who need to scrape Telegram groups for outreach lists, back up their own communities, migrate member data, or analyze conversations — without copy-pasting by hand. ━━━━━━━━━━━━━━━━━━━━━━━━ 💳 PLANS ━━━━━━━━━━━━━━━━━━━━━━━━ Free to start with monthly export limits. Every mode is unlocked on every plan — paid plans raise the monthly volume, not the feature set. See current pricing in the extension. ━━━━━━━━━━━━━━━━━━━━━━━━ 🚀 GETTING STARTED ━━━━━━━━━━━━━━━━━━━━━━━━ 1. Install and open Telegram Web (web.telegram.org). 2. Open the Mastros sidebar from the edge pill or the toolbar icon. 3. Pick what to extract, run it, and export to Excel, CSV or JSON. ━━━━━━━━━━━━━━━━━━━━━━━━ 🔑 AUTHENTICATION INFORMATION ━━━━━━━━━━━━━━━━━━━━━━━━ None required. Mastros does not ask for a Telegram API ID or hash, a phone number, a login code, or a password, and it has no account system of its own. It reads through the Telegram Web session already open in your browser, and only ever accesses what that session can already see. ━━━━━━━━━━━━━━━━━━━━━━━━ ⚖️ COMPLIANCE ━━━━━━━━━━━━━━━━━━━━━━━━ Not affiliated with, endorsed by, or connected to Telegram. You are responsible for lawful use of exported data and for complying with applicable privacy laws and Telegram's terms. No bulk messaging, no auto-adding, no automation — Mastros only reads and exports.
