Extension for Chrome

Hello! I have experience in automating Telegram parsing and writing user bots. I will do everything quickly and without using browser extensions.

As you rightly noted in the update, Chrome extensions handle large files (videos of several GB) poorly and heavily load the system. I will implement this through a standalone Python script.

Hello.

Yes, it is possible to implement such a task. I would like to note right away: if a stable result is important, then for exporting a closed Telegram channel with large files, sorting by hashtags, and organizing into folders, it is more reliable to create a separate tool/script that works through your authorized access rather than a regular Chrome extension. This way, the solution will be more stable and better handle large volumes of files without constant interruptions.

What can be implemented:
downloading the entire channel or individual posts, exporting files based on your access, sorting into folders by hashtags and date, processing large files, as well as a more convenient batch upload logic.

If a Chrome option is fundamentally necessary, that can also be discussed, but in terms of reliability, I would recommend a separate solution.

… Cost estimate: 300 USD
Deadline: 6 days

I am ready to clarify details regarding the volume of the channel, types of files, and the desired format of the result.

Good day!
I represent the company Devoxen.
We can help with the development of a solution for mass downloading of files from Telegram with convenient sorting by hashtags, dates, and individual posts. If the option with a Chrome Extension turns out to be unstable for large volumes of data, we can offer a more reliable implementation using an alternative method to ensure stable downloads without session interruptions and with proper handling of large files.
We have experience in developing custom automation tools and solutions for specific business tasks, so we can select the optimal implementation format specifically for your scenario and required result.
On our part, we will prepare a commercial proposal with implementation options and work stages.
We also provide a guarantee: if errors or shortcomings are identified after launch, we will promptly fix everything.
Let's discuss the details in private messages.

Good day, Igor!
In general, the task is clear, but for an accurate response regarding deadlines and price, I would like to clarify some questions that arose after analyzing your task.
Please write in private messages — we will discuss the details and your wishes.

Hello.

Straight to the point: for your task, I would recommend not a Chrome extension, but a separate local tool. The reason is simple - when exporting a large closed channel with heavy files in bulk, it will be noticeably more stable and convenient to operate.

I can implement an MVP with the following functionality:
* export of the entire channel
* export of a single post
* saving to a selected folder
* automatic creation of folders in the format "date + hashtag"
… * processing of large files with retries and normal continuation of the process

In other words, the method of implementation will be chosen for reliability, rather than being tied specifically to Chrome, which is more important in your case.

If you are interested, I will write right away about how to better organize the work format and what needs to be clarified before starting.

Good evening
My name is Angelina, representing the company King Kong Lab
The task is clear, we can implement a turnkey solution. We have done similar work with Telegram Web and content extraction, so we understand the limitations and nuances
I will say right away that the option through a Chrome Extension is possible, but it is really not the most stable for large volumes. It is more reliable to create a separate script/application through the Telegram API, which will work faster, more stably, and without overloading the browser
What we can implement
extraction of the entire channel or individual posts
working with large files without interruptions with resuming
distribution of files into folders by hashtags and date
automatic creation of folder structure
… the ability to start extraction with one button
It is also possible to provide logic so that the system correctly processes large channels and does not lose data during failures
We will be able to say more precisely after clarifying the nuances of access and the format of work
We are ready to offer an optimal architecture and implement a stable solution
I look forward to collaborating

Hello!

We are a team that has been developing bots for over five years. Our main tools are NodeJS and Python. We also work with any databases (MongoDB, SQL, Postgres, etc.), integration with payment systems, API services, and plugins.

Downloading gigabytes of video through a browser extension (parsing Telegram Web) is an extremely unstable method. The browser will consume a huge amount of RAM, the tab will eventually freeze, and at the slightest interruption in the connection, the download will stop without the possibility of normal recovery. The ideal, most reliable, and fastest alternative method for your task is to write a small Python script (UserBot) using the Telethon or Pyrogram library.

After completing the development, we guarantee to provide technical support and consultations for 10 days.

You can find examples of already implemented and working products on our website - https://vaysed.me/ or in the freelance profile.
…
We look forward to your response!

Good evening! I have a similar code that performs your functionality, it will just need to be written so that it works as an extension. Or I will make any wrapper that will be convenient for you.

Hello! You are absolutely right: downloading gigabytes through a Chrome Extension is a way to freeze the browser and interrupt downloads. Browsers are not designed for such data streams.

I propose a reliable engineering approach: a local script in Python that works directly through the official Telegram API (MTProto) on behalf of your account.

How this solves all your tasks:

No crashes and load: The script downloads files in a streaming manner directly to the hard drive. Memory consumption will be minimal (about 50-100 MB), and the session will not be interrupted even with files of 5-10 GB.

Accurate sorting: The script instantly reads the text of the post, finds the hashtag (for example, #bear) and the publication date. The creation of the folder structure [Date] [Hashtag] happens automatically.
…
Any channels: Since the script authorizes through your phone number/session, it has access to all closed channels you belong to.

Download flexibility: I will create a convenient management menu.

My background (high-energy physics) has trained me to create reliable systems for processing large data without packet loss. The script will work like Swiss clockwork.

Good evening! I carefully studied the technical specifications. The logic with folders, hashtags, and dates is clear - we can do this without any problems. However, there is one critical technical point regarding the Chrome Extension, which is why I suggest slightly changing the approach to ensure everything works stably.

The main problem is point 2 (downloading 100% of files of a couple of GB without interruption). The thing is that Telegram Web collects large media files in chunks directly in the browser's RAM. If we try to download even a few gigabyte videos through the Chrome extension, the tab will simply freeze and crash due to lack of memory. The browser physically cannot handle the "bulk" download of a heavy channel; the session will constantly crash.

How to do this reliably: I suggest writing desktop software (a script in Python) that will work through the Telegram API from your account.

How this will cover all your tasks:
1 - Easily reads the closed channel to which you have access.
2 - Files are downloaded directly to the PC's hard drive, bypassing the browser. RAM is not filled up; you can download gigabyte archives for days on end - nothing will be interrupted or freeze.
… 3 - You can start downloading the entire channel "in bulk."
4 - You can download selectively (for example, simply by pasting the link to the desired post).
5 - The program will automatically read the publication date, find the necessary hashtag (for example, #bear), and neatly organize the files into folders like "01.01.2001 bear."

As a result, you get exactly the outcome you need, only the program will work like a tank, without browser crashes.

Greetings. I have done something similar, but not as an extension. I will implement it. I will refine it.

Included:
- downloading the entire channel or individual posts
- working with large files
- sorting by folders (date + hashtag)

Additionally, we can discuss resilience (continuation of downloads after stopping) and advanced filters.
