Supported Google Models

EraseMark is purpose-built to recognize the specific visible watermark alpha masks and corner geometries deployed across Google's generative AI ecosystem:

Nano Banana & Gemini 2.5

Full support for experimental Gemini 2.5 Flash and Pro image outputs carrying the signature bottom-corner sparkle overlay.

Google Imagen 3

Standard 1024x1024, 2048x2048, and widescreen generations produced by Google's flagship text-to-image foundation model.

Google Veo 2 & Veo 3

720p and 1080p high-definition video clips generated via Google Veo, processed frame-by-frame entirely inside your browser.

Google Flow Workspace

Media created through Google's experimental creative interfaces and web workspaces with semi-transparent corner badges.

How EraseMark Removes Watermarks Without Blurring

Unlike generic online watermark removers that use blurry AI inpainting to smudge or paint an artificial patch over your image, EraseMark uses mathematical reverse alpha unblending.

When Google embeds a visible watermark, it blends a semi-transparent white logo over your background pixels using standard alpha compositing: C_blend = (1 - α) × C_original + α × C_watermark.

Because the exact pixel coordinates, logo color, and alpha channel (α) of Google's watermark are mathematically known, EraseMark calculates the exact inverse: C_original = (C_blend - α × C_watermark) / (1 - α). This restores the original underlying pixels with zero blur, zero halo, and pixel-perfect fidelity.

Privacy, SynthID & Ethical Disclosure

100% Client-Side Privacy

Your photos and videos are never transmitted to any external server or cloud database. All decoding, pixel math, and file rendering happen locally in your browser memory.

SynthID & Invisible Metadata

EraseMark removes only the visible human-readable corner overlay. It does NOT remove or modify Google DeepMind SynthID frequency-domain watermarks or C2PA provenance metadata.

Frequently Asked Questions

Is EraseMark completely free to use?

Yes. EraseMark is 100% free with no account creation, no subscriptions, and no hidden file export limits. Processing runs on your device, requiring zero expensive cloud server resources.

Are my images or videos uploaded to any server?

No. Your files never leave your device. All image and video processing takes place entirely inside your web browser using HTML5 Canvas and client-side WebAssembly.

Will watermark removal make my images blurry?

No. EraseMark does not use blurry inpainting or generative smudging. It uses exact mathematical reverse alpha unblending to calculate and restore the original pixel values directly.

Does EraseMark remove Google DeepMind SynthID?

No. EraseMark only removes the visible corner sparkle watermark. SynthID is an imperceptible, cryptographic watermark embedded in the frequency spectrum of the media and remains intact.

Does it work on images and videos I previously downloaded?

Yes. Any Gemini, Nano Banana, or Google Veo file with the default corner watermark can be dropped into EraseMark at any time to remove the overlay.

What file formats are supported?

For images, we support PNG, JPEG, WebP, and AVIF up to 4K resolution. For videos, we support MP4 and WebM formats with full audio stream preservation.
