Embed Watermark

What is Watermark Embedding?

Watermark embedding is a technology that hides information invisible to the human eye within an image's pixel data. truvis uses Adobe TrustMark technology, allowing you to embed up to 8 ASCII characters into an image. The embedded information can be detected with high accuracy even after common image processing such as JPEG compression and resizing.

Embedding Tips

• For payloads, we recommend strings that can identify the copyright holder (such as initials or management numbers).
• Higher resolution images allow for more stable embedding. A minimum size of 256×256 pixels is recommended.
• Saving in PNG format maintains the highest fidelity. JPEG format also offers sufficient robustness, but avoid extremely low quality settings.

How Watermark Embedding Works

Adobe TrustMark, the technology behind truvis, is a state-of-the-art digital watermarking system powered by neural networks. Unlike traditional frequency-domain embedding methods, a deep learning model analyzes the image's features and embeds information while preserving visual quality. Specifically, an encoder network takes the input image and payload (watermark text) and transforms the image at a level indistinguishable to the human eye. This approach achieves high robustness against various image processing operations, including recompression during social media uploads, resizing, and screenshots.

Use Cases for Watermark Embedding

How to Use (3 Steps)

1. Step 1: Upload an image — Drag and drop or select an image file in PNG, JPEG, or WEBP format. A minimum resolution of 256×256 pixels is recommended.
2. Step 2: Enter a payload — Enter up to 8 ASCII characters. Use a string that helps with identification, such as the author's initials or a management number. You can also generate a random string using the "Random" button.
3. Step 3: Encode and download — Click the "Encode" button to start processing. After completion, review the preview and download the result in PNG format.

Frequently Asked Questions

Is the embedded watermark visible?

No, the watermark embedded by truvis is invisible to the human eye. Since it works by making subtle changes to the image's pixel data, there is virtually no visible difference from the original image. This allows copyright protection without compromising image quality.

What image formats are supported?

PNG, JPEG, and WEBP formats are supported. Regardless of the input image format, the watermarked image is downloaded in PNG format. This minimizes degradation of watermark information due to compression.

Does the watermark survive social media uploads?

Most social media platforms resize and recompress images, but TrustMark technology has high robustness against these operations. However, extreme cropping or significant size reduction may reduce detection accuracy. See our SNS Watermark Durability Guide for details.

Can I change the payload after embedding?

Once embedded, the payload cannot be changed afterward. If you want to use a different payload, re-encode from the original image (without watermark). Re-encoding an already watermarked image will overwrite the previous watermark.
