About Demarker
What we do
We show you what an image carries in three layers: visible marks, AI metadata, and hidden watermarks inferred from the metadata. Then, if you want, we remove known visible marks, strip AI provenance metadata and, with the GPU pass, regenerate the image to disrupt hidden watermarks.
What we keep
Creator and copyright fields stay in your file by default. We take out AI provenance fields only. We cannot check hidden watermarks.
What we will not do
We do not remove stock-photo or marketplace overlays, we do not remove tools like Glaze or Nightshade, and we refuse adult content. We do not claim the result is undetectable, because we cannot decode hidden watermarks to check. The service is not available in mainland China, and in India only the free scan is offered.
Your images
Originals are deleted 24 hours after the last run on them finishes, or after upload if you never process, and up to 72 hours while a job awaits payment. We never use your images for training. You can delete an image at any time.
Labelling duties
Some places require AI-generated or AI-edited content to be labelled, including the EU AI Act, China and India, and the places you publish may have their own rules. Removing a mark from a file does not remove that duty. Use this service on images you own or have the right to edit.
