Remove the Doubao (豆包) watermark from your images.

ByteDance's Doubao (豆包) image generator stamps a small white “豆包AI生成” text strip into the bottom-right corner of every output. The strip is partially transparent and scales roughly proportionally with the image dimensions: a few hundred pixels wide on a typical Doubao output. Because it covers actual image pixels with semi-transparent text, a Doubao watermark remover has to reconstruct the area underneath rather than just reverse a clean overlay.

That reconstruction is what makes the problem hard. A naïve column-fill blurs the area; a generic AI inpainting tool works but treats every Doubao image like an unknown blob. This Doubao Watermark Remover targets the specific watermark and runs the right algorithm — designed for one job and tuned for it.

The pipeline begins with a luminance-based detection step. It searches a tight region near the bottom-right corner for white-ish pixels (R, G and B all above 220 with low colour spread) and computes the bounding box of the “豆包AI生成” text. This adapts automatically to whatever size Doubao chose for the watermark in your specific output, so the algorithm doesn't depend on an outdated fixed-position table.

On desktop, the Doubao Watermark Remover then crops the watermark region plus 40 pixels of context, builds a binary mask, and runs MI-GAN — a 27 MB ICCV 2023 inpainting model — locally in your browser via onnxruntime-web. The model reconstructs the underlying pixels from the surrounding context. The reconstructed crop is composited back into the original image at full resolution.

On mobile, the tool automatically swaps to a lightweight column-median fallback that doesn't load a model. Quality is lower than the AI inpainting on desktop, but it avoids the iOS Safari memory-pressure crash that would otherwise kill the tab.

Reach for the Doubao watermark remover when you need a clean Doubao output for a content workflow — a social post, a thumbnail, a banner, a personal archive. The tool is fast, free and unlimited: drop one image or a folder, and download single results or the whole batch as a ZIP.

We provide it for personal, research and creative use. Removing the “豆包AI生成” strip does not change the licensing of the underlying content — you remain responsible for respecting ByteDance's Doubao terms of service.

Several other sites marketed as a “Doubao watermark remover” require you to upload your image to their server. We don't. The tool runs the entire detect-and-inpaint pipeline locally in your browser. The MI-GAN model is downloaded directly to your device on first use and cached there; your image data never leaves the browser sandbox.

You can audit this in the browser's network panel: drop a Doubao image in and watch — the only outbound traffic is the static page assets and (on desktop) the one-time MI-GAN download. No request ever carries the bytes of your image.

It works best on the original PNG, JPEG or WebP that Doubao produced. Screenshots, recompressed exports, or images that have been edited in a third-party tool may have the watermark pixel values shifted, which can reduce detection accuracy. If detection fails, the tool returns your image unchanged with a clear message.

On busy backgrounds (lots of fine texture), the inpainted region can show subtle differences from the rest of the image even with MI-GAN. For uniform backgrounds — the most common Doubao output style — the result is usually visually seamless.
