Telegram 视频下载器 - ExtStack 作者： Justin

Telegram Video Downloader - ExtStack is a Chrome extension for saving media, images, and audio from Web straight to your device. The downloader works entirely in your browser, making it simple to archive conversations, back up photos from groups, or collect audio messages without switching apps. Whether you are collecting resources from tg channels or backing up personal memories, this tool handles every step so you can save exactly what you need.

📋 Features

1. Automatic Media Scanning — The downloader scans open chats on web.telegram.org and surfaces all downloadable files including photos, voice notes, and audio clips automatically. Medias appear in the gallery as you scroll, keeping the list current with no manual refresh required. New items are detected continuously, so nothing gets missed even in active tg conversations with hundreds of messages.
2. Smart Category Filtering — Use All, Video, Image, and Audio tabs to filter your gallery by type. Count badges update live so you can instantly see how many items belong to each category before initiating any save. Images and audio are labeled clearly, letting you isolate exactly what you want from your tg chat history.
3. Flexible Batch Selection — Click rows to select specific files or use Select All to grab everything visible. The downloader remembers selections across filter changes, so you can build a custom list from multiple categories. You can mix photos, clips, and audio into one selection and save them all together in a single batch.
4. Download and ZIP Modes — Download Selected delivers files individually to your browser folder. For bulk saves, Download as ZIP bundles your entire selection into one archive. Both modes show live progress bars with file counts, byte progress, and ETA so you can track exactly what is being saved and when it will finish.
5. Daily Quota with Upgrade Path — Free accounts get 5 downloads per day, tracked in the side panel counter. When the limit is reached, downloads pause and an upgrade prompt appears. Pro removes all restrictions for truly unlimited export from any tg chat or channel.

🎯 How to Use

1. Add the downloader to Chrome from the Web Store and pin the icon to your toolbar for quick access whenever you visit web.telegram.org.
2. Open any chat, group, or channel on Web containing videos, images, or audio. The side panel activates automatically and begins detecting all available files, populating the gallery as content loads in the conversation.
3. Apply the filter tabs to narrow the view by type. Each category shows its own count badge so you can assess what is available before saving files from this particular chat or channel.
4. Check the boxes next to files you want, or click Select All to grab everything visible. Choose Download Selected for individual delivery or Download as ZIP to bundle everything into one archive.
5. Watch the quota counter at the top of the panel. Free users get 5 saves per day; upgrade to Pro at any time through the in-panel prompt for unlimited access.

💰 Pricing

Pro subscribers enjoy unlimited downloads and unlimited ZIP exports. The upgrade is a one-time purchase processed through ExtensionPay, a trusted third-party payment platform. Pro status links to your ExtensionPay account and works across all your Chrome profiles.

Click the upgrade button whenever you hit your free limit, or choose the in-panel promotional banner at any time for instant activation with no re-verification needed on future sessions.

❓ FAQ

Can the downloader access private chats?
No. The tool only works with media already visible in your active Web session and cannot bypass privacy settings or access any content you are not authorized to view.

Can I save images from video clips?
Yes. Video clips sent as files are detected by the scanner and appear in the gallery alongside standard photos. You can save them individually or bundle them with other images into a ZIP archive for easy sharing.

What formats does the tool support?
The save system handles common video, image, and audio formats detected in your chats. All detected medias appear in the gallery with type labels and file sizes for easy verification before saving. The gallery also surfaces medias stored as file attachments within the tg chat history, making it easy to find video clips, photos, and other media sent as files.

Are there size limits for ZIP export?
ZIP bundles have practical per-file limits. Files exceeding the threshold are excluded and noted in a _failed.txt inside the archive so you know exactly which items did not make it into the package. For very large batches of tg media spanning hundreds of files, consider splitting into multiple smaller archives to ensure every video and image is properly bundled and the process remains stable.

How is the free daily quota calculated?
Free accounts receive 5 export slots per calendar day, resetting at midnight in your local timezone. Each file counts as one slot regardless of its file size. Pro accounts have unlimited downloads with no daily reset, which makes them ideal for heavy users who manage large volumes of tg media regularly without interruption.

Do selections survive filter changes?
Yes. Selected files persist when switching between categories, so you can build a mixed selection across All, Video, Image, and Audio views without losing your progress. Closing the tab or starting a new session clears the selection.

Can I cancel a ZIP export mid-process?
Yes. Click the X button in the ZIP progress card to cancel at any time during the export. The tool stops after the current item finishes downloading and discards the incomplete archive. No partial ZIP file will be saved to your disk.

Does it work on mobile browsers?
No. This extension only works in the Chrome desktop browser at web.telegram.org. Mobile Chrome, other browsers, and desktop or mobile apps are not supported.

Why does the side panel sometimes show fewer medias than I expect?
The downloader only detects medias that have been loaded into the DOM by Web. If a chat contains hundreds of older messages, you may need to scroll up to trigger the interface to render additional media. The scanner works continuously as you scroll, gradually building the complete list of available items. For very active tg channels with thousands of medias, allow a few seconds of scrolling to let the scan catch up. Some older medias may also be stored on Telegram servers rather than loaded in the DOM, and those will appear once you scroll into view.
