★How to Batch Download Water, Watermark-Free Images and Videos from Doubao AI (2025 Working Method)★

If you’ve ever spent hours chatting with Doubao AI (doubao.com) and ended up with dozens or even hundreds of stunning AI-generated images and videos, you know the pain: the official site only lets you save them one by one, and every saved image comes with an ugly watermark.

There’s now an open-source tool that completely solves this — doubao-downloader. It works as either a browser extension or a Tampermonkey/Violentmonkey userscript and lets you download all images and videos from the current conversation in their original watermark-free quality with a single click.

Two Easy Ways to Install It (Tested November 2025)

Method 1: Tampermonkey / Violentmonkey Userscript (Recommended — takes 10 seconds)

Perfect if you already use Tampermonkey, Violentmonkey, or any other userscript manager.

Steps:

  1. Go to the Releases page:
    https://github.com/LauZzL/doubao-downloader/releases
  2. Download the latest doubao-downloader.user.js
  3. Open your userscript manager → “Create a new script” → paste or drag the file in
  4. Save and refresh doubao.com — done!

Method 2: Install as a Chrome/Edge/Brave Extension

  1. Download the .crx or .zip file from the same Releases page
  2. Open chrome://extensions/ (or the equivalent in your browser)
  3. Enable “Developer mode” in the top-right corner
  4. Drag the .crx file directly into the page, or unzip the .zip and click “Load unpacked”
Load unpacked extension

Once installed, a small floating window appears in the bottom-right corner of doubao.com showing every image in the conversation.

How to Download Watermark-Free Videos

Yes, videos work too — completely without watermark.

In short: when Doubao finishes generating a video, its thumbnail appears in the floating panel. Click the download button on the right and you get the original clean file.

Frequently Asked Questions (FAQ)

Q: I installed it but nothing shows up?
A: Make sure you’re on the official https://www.doubao.com (some mirror sites won’t work). Hard refresh the page (Ctrl + F5).

Q: Some images are missing from the panel?
A: Doubao loads images lazily. Scroll through the entire conversation so every image loads — the panel updates in real time.

Q: Downloaded images still have watermarks?
A: Extremely rare. The tool hooks JSON.parse and grabs the raw URLs before the watermark layer is added. If it ever happens, it means Doubao changed their API — open an issue on GitHub.

Q: Does it work in Firefox?
A: Yes, 100%. Just use the userscript version with Tampermonkey or Violentmonkey.

Q: Will I get banned for using this?
A: The tool only reads data your browser already receives. No extra requests are sent, so the risk is practically zero.

Q: Can I use it on other AI image platforms?
A: Currently it’s built specifically for Doubao’s unique API structure.

Q: I want to add dark mode / auto-folder by conversation — possible?
A: Absolutely. The project is fully open source. Feel free to submit a PR or open a feature request.

Why This Works So Well (The Clever Part)

Doubao’s web client already receives the clean, watermark-free image URLs from the backend. The watermark you see is just a CSS overlay added on the frontend. By overriding JSON.parse, the extension intercepts the original URLs before the page has a chance to add the watermark layer. That’s why you always get pristine files.

If you generate a lot of AI art or use Doubao professionally, this little tool will save you hours every week.
