# Delete SynthID

> Delete SynthID processes AI-generated images that the user owns. It targets supported visible AI marks and removable provenance metadata, and uses pixel regeneration to disrupt embedded watermark signals. Results vary; the service does not guarantee removal of every embedded signal.

## Product

- New users sign in with Google and receive one free image credit.
- One credit processes one image. Additional credits are one-time, non-refundable purchases with no subscription or renewal.
- A credit is returned if an accepted processing job fails permanently.
- Supported uploads are JPEG, PNG, WebP, AVIF, HEIC, and HEIF images up to 20 MB.
- Originals and results are stored as private Cloudflare R2 objects. They currently have no automatic expiry or deletion and remain stored until a deletion workflow is implemented.
- Processing runs on a remote isolated CPU worker. The processing command executes inside a Docker container with networking disabled; the host handles database and private object-storage access.

## Pricing

Users may choose any whole image quantity. The per-image price for the entire purchase changes when the quantity crosses a threshold:

- 1–9 images: $2.00 per image
- 10–99 images: $1.50 per image
- 100–499 images: $1.20 per image
- 500 or more images: $1.00 per image

These are quantity thresholds, not fixed packs. For example, 12 images cost 12 × $1.50. Purchases are one-time and non-refundable, and there is no subscription.

## How image processing works

1. The user uploads a supported image to private object storage.
2. A remote CPU worker claims the processing job and downloads the private input.
3. The host starts the processing command in a Docker container with networking disabled and preloaded models.
4. The host uploads the result to private object storage, where it becomes available through the user's authenticated account.

Processing may change fine details. It does not erase the original file, copies shared elsewhere, or a platform's server-side records. There is no local decoder for every proprietary embedded watermark, so a processed output is not a guarantee that every verifier will return a negative result.

## Responsible use

Delete SynthID is for images the user generated or otherwise has the right to modify. It is not intended to remove stock-photo, copyright, purchase-gating, or artist-protection watermarks.
