Disclosure: this is a product guide from the ExtStack team.

Telegram chats can contain a mixture of videos, pictures, voice notes and audio files. When you want a personal backup of media you are permitted to save, selecting the right files matters as much as downloading them.

Telegram Video Downloader - ExtStack is a desktop Chrome extension that puts this workflow in a side panel beside Telegram Web. This guide explains the features described in its Chrome Web Store listing and the limits to keep in mind.

Start with the media already available to you

Open Telegram Web in desktop Chrome and navigate to the chat, group or channel containing your media. The extension scans the media that Telegram Web has loaded into the active conversation.

That last detail matters for long chats: older messages may not yet be loaded. Scroll back through the conversation to load more content before expecting its media to appear in the extension. A small gallery does not necessarily mean there are no older files.

The tool works with content you are already authorized to view in your current session. It cannot bypass privacy settings or retrieve inaccessible conversations.

Narrow the gallery before selecting files

The side panel provides All, Video, Image and Audio filters. Use a category when you only want one type of media, rather than selecting every visible file immediately.

You can choose individual items or use Select All for the visible selection. Selected items stay selected when you switch category filters, so a batch can contain both pictures and audio without rebuilding the selection each time.

For a practical backup workflow, review the category you need first, select the relevant files, then check another category if it belongs in the same archive. Keep the selection focused on content you need and have permission to save.

Choose individual downloads or a ZIP archive

There are two ways to export the selection:

  • Individual downloads save the selected files separately.
  • ZIP export groups the selected files into one archive.

The extension displays progress information while the export runs. ZIP export is useful when you want to keep related media together, while individual downloads suit a smaller selection you plan to organize separately.

Understand the free tier

The free tier includes five media saves per day. Pro is an optional one-time purchase through ExtensionPay that removes the download and ZIP-export limits. Check the current store listing before deciding whether the free tier covers your workflow.

Browser and privacy scope

According to the product listing, media processing takes place locally in the browser. This extension is intended for desktop Chrome at web.telegram.org; mobile Chrome and the standalone Telegram apps are outside its supported workflow.

ExtStack is an independent tool and is not affiliated with Telegram. Download only media you are authorized to access and permitted to save.

You can find the product information on the official ExtStack website and install the extension through its Chrome Web Store page.
