If you've ever subscribed to a creator who had hundreds of posts and thought to yourself, "I wish I could just get all of this without going through every single one" — that's what a bulk downloader does.

This guide covers how to download OnlyFans content in bulk using a Chrome extension, what you can actually save, and a few things worth knowing before you start.

---

## What "Bulk Download" Actually Means on OnlyFans

OnlyFans doesn't include a built-in download feature. Every photo and video sits behind their player, and the platform doesn't make it easy to save content locally.

A bulk downloader works differently from trying to right-click and save. It accesses your account's media library through your active browser session — the content you've already paid for — and downloads it to your computer in one go, organized and labeled.

You're not bypassing any paywall. The content needs an active subscription (or purchase history) to show up. Think of it less like a download hack and more like an offline backup tool for things you've already bought.

---

## What You Can Download in Bulk

With **Mass.Downloader** (the Chrome extension at hotfansdownload.com), there are three content sources:

**Posts** — everything a creator has published on their feed that you have access to. This includes photos and videos from free posts, paid unlocks, and your subscription tier.

**Purchased** — media you've bought individually, like PPV messages and unlocked content. This one's useful because it stays available even after you cancel your subscription. If a creator deletes their account tomorrow, your purchased content is still downloadable today — as long as you haven't cancelled yet.

**Chats** — photos, videos, and audio files sent to you in direct messages. Easy to overlook, but often where the most exclusive content ends up.

---

## How to Set It Up

### Step 1: Install the Extension

Mass.Downloader isn't on the Chrome Web Store — it was removed due to platform policies, which is common for this type of tool. You download the ZIP file from [hotfansdownload.com](https://www.hotfansdownload.com), extract it, and load it manually.

Here's how:
1. Go to `chrome://extensions` in your browser
2. Toggle on **Developer mode** (top right corner)
3. Click **Load unpacked**
4. Select the extracted folder

The extension icon will appear in your toolbar.

### Step 2: Log Into OnlyFans

Open OnlyFans in the same browser and make sure you're logged in. The extension reads your active session — it doesn't ask for your password or store your credentials.

### Step 3: Open the Extension and Choose What to Download

Click the extension icon. You'll see your subscribed creators listed. Select one (or all), pick your content source — Posts, Purchased, or Chats — and hit download.

## Tips for Large Downloads

**Turn off "Package downloaded files" for big libraries.** The default setting bundles everything into a ZIP, which works fine for small batches. But downloading 50+ videos this way can crash your browser tab due to memory limits. Switch to sequential mode instead — files download one at a time directly to your downloads folder.

**Use Fast Scan once you've done an initial backup.** Full Scan checks every post from the beginning. Fast Scan only picks up new content since your last download. After you've archived everything once, Fast Scan is what you'll use going forward.

**Downloads can be paused and resumed.** OnlyFans session tokens expire after a while — that's just how the platform works. If a download stalls halfway through, hit Resume. You don't have to start over.

---

## Free vs Pro

The free version caps you at 10 photos and 2 videos per task — good for testing but not practical for real archiving. The Pro plan ($12/month or $14 as a one-time payment) removes those limits and raises the ceiling to 10,000 photos per task.

There's a 7-day refund window if something doesn't work as expected.

---

## A Few Common Questions

**Will OnlyFans know I'm downloading?**
The extension operates through your normal browser session — the same way you'd watch a video. There's no aggressive scraping behavior. That said, downloading thousands of files in a very short window is something to be sensible about.

**Does the downloaded content have a watermark?**
No. Files download as the original media without any added watermarks from the extension. OnlyFans itself sometimes bakes creator watermarks into the content — those are part of the original file and will be there regardless.

**Can I download from creators I'm not subscribed to?**
No. The extension only shows content your account has legitimate access to.

---

Bulk downloading sounds more complicated than it is. Once the extension is set up, the whole process takes maybe two minutes per creator. For anyone building a local archive of content they've paid for, it's a straightforward solution.

## I purchase Pro plan. How can I confirm that it is Pro?

Both on pages for fetching media list and downloading media, there is a tag indicating whether the current version is "Pro" or "Free".

The free version only allows downloading 10 photos and 2 videos. The pro version can download up to 10,000 photos per download task. If you have more than 10,000 photos, you can use incremental download multiple times to complete the download of all media.

![Alt Text](/guide/pro_tag.png)

Second way to confirm that is you could find an "unsubscribe" button on the pro page.  As shown below, once you get subscribed, the "Subscribe" button will be replaced by "Unsubscribe" button which guides you to the unsubscribe page.

## Three options of download from

Before starting the download, you need to choose where to get the media list from. There are two options: "posts" and "purchased." Below, we will explain their differences in detail.

## Downloading from posts

Downloading from "posts" is relatively easy to understand. It means downloading the media from posts that a specified creator has previously published.

## Downloading from purchased

Downloading from "purchased" refers to bulk downloading all the media you have previously bought. This media could have been purchased from posts or during chats with the creator.

Unlike subscriptions, when a subscription expires, you can no longer view the creator's posts. However, the media you purchased remains in your purchased list.

If you purchased media during a chat with the creator and later cleared the chat history, don’t worry. You can still find it in your purchased list.

## Downloading from chats

Downloading from "chats" refers to the process of retrieving all the media sent from creators. Not only can you download photos and videos from chats, but you can also download audio files.

## What is Incremental Download?

Firstly let explain full download. Full download will scan all posts and download all the photos and videos involved in those posts. However, incremental download will only add the medias that have not been previously downloaded to the download list.

## Full Scan and Fast Scan

In incremental download, there are two scanning modes: full scan and fast scan. Full scan will scan all the posts of the creator, while fast scan will only scan the posts that have not been previously scanned.

## Why We need Incremental Download?

Full download is used for target creator accounts that have not been archived before. After that, full download is no longer necessary. By performing incremental downloads periodically, you can ensure that the locally saved content stays synchronized with the online media. In incremental download, using fast scan is faster compared to full scan.

We recommend using full scan whenever possible. Let's consider a scenario: in the previous download, you only downloaded photos, but this time you want to download the latest photos as well as videos. By choosing full scan, not only can you obtain the latest medias, but you can also retrieve the videos that were not downloaded in the previous session.

## How to?

Before downloading, checking the "incremental download" checkbox will enable the use of incremental download.

In the settings page of the popup, you can switch between fast scan and full scan. The default setting is full scan.

## What is the problem

According to some users' reports, when opening the plugin, an infinite login situation occurs.

## Description of problem

According to his description, after clicking the Google login button, a Google third-party login window appears. After entering the Google account, the third-party login is successful, and the login window closes. However, when opening the plugin again, it still prompts for the need to log in with Google.

## Debug the problem

After debugging, we discovered that the issue lies in the fact that after logging in with Google, the plugin's popup should be open. In this scenario, however, the popup page of the plugin is closed. Consequently, this leads to an infinite login situation because the plugin detects a successful Google login and displays the dashboard button while the popup is closed.
This issue occurs on a small number of users' computers and appears to be specifically related to the user's region. Currently, there is no good solution available, but there is a workaround.

## Solution

Once the popup window appears, right-click and hover over the "Google login" button .
![Alt Text](/guide/google_login.png)
Click on the menu that appears and select the "Inspect" option. This will open the developer debugging mode, and a debug window will pop up at the bottom.
![Alt Text](/guide/debug_window.png)

At this point, click on the "Google login" button again and complete the login process. This workaround leverages the fact that the debug window remains open, allowing for a successful login.

Mass Downloader will remember the login state, so there is no need to log in again the next time.

## What is problem with large download job?

When downloading a large number of media files, it is common to experience freezing or getting stuck, indicated by the progress bar staying at a certain percentage without further progress. This typically suggests a failed download of a particular media file, causing the download process to halt.

## Why?

There are various reasons for download failures, such as unstable network connections or the computer entering sleep mode.

In the case of OnlyFans, each media file is associated with a unique token that is required to initiate the download from the current IP address. These tokens periodically change and are matched with the IP address at that time. During a large download job, if the token is updated, it can result in a download failure. Additionally, if you are connected to a cellular network, unlike office or home broadband networks where IP addresses remain relatively stable, the IP address on a cellular network can easily change, causing the token to become invalid and leading to download failures.

Furthermore, the OnlyFans website itself may experience instability, which can often result in the inability to browse media.

## Our Solution
Fortunately, we have developed a resumable download feature. When getting stuck, it allows us to resume the download from the point where it left off, without having to re-download the media that was already completed in the previous attempt.
[Click to Install](https://pub-6f94f4b4cdeb4b63b682e942191aff9e.r2.dev/Mass-Viewer-for-Onlyfans.zip)

## How to use it?

When on the download page, if you notice that the progress bar is not updating for an extended period, you can click the 'Get Stuck' button to return to the home page.

![Alt Text](/guide/resume_01.png)

On the home page, you will find a "Resume Download" button. Clicking on it will rebuild the download list and continue downloading from the last downloaded media file in the previous session.

![Alt Text](/guide/resume_02.png)

## One More Benefit

This functionality can also be used for pausing and resuming downloads. Suppose you need to shut down your computer to attend to something else while a download is still in progress. In that case, you can pause the task and resume it when you're ready to continue downloading.

## What is problem with downloading 50+ videos?

When downloading using the plugin, by default, all videos and images are downloaded and compressed into a single file. When attempting to download more than 50 videos at once, it's highly likely to exceed the available memory of the browser, resulting in a failed download.

## Our quick solution:

We just work out a temporary solution by providing a toggle switch for the option of downloading and package files as one zip file. When the "package the downloaded files" setting is turned off, the plugin will download the files one by one.
[Click to Install](https://pub-6f94f4b4cdeb4b63b682e942191aff9e.r2.dev/Mass-Viewer-for-Onlyfans.zip)

Even with this solution, it cannot guarantee smooth downloading of hundreds of videos at once. We design additional features such as on-demand downloading and automatic resuming of downloads from incomplete files.

## How to use it?

The entry to toggle this switch is located in the "Settings" page under the option "Package the downloaded files."
![Alt Text](/guide/over_20_videos.png)

## Suggestion:

If you're only downloading photos or a small amount of video, we recommend you turn on "Package the downloaded files."

## Important Notes:

1. To support automatic downloads, please turn off the following settings in Chrome.
![Alt Text](/guide/auto_download.png)

2. Please note that each file will automatically open after being downloaded, such as a video being opened in the default media player. Therefore, please be cautious and avoid using the plugin in public places or office environments.

As to DRM-protected videos, We are still researching it, so downloading such videos is currently not supported.
