Frequently Asked Questions
Do I need to watermark GPT Image 2 outputs?
Ethically and often legally, yes. Platforms like X, Instagram, and Meta properties increasingly require disclosure when content is AI-generated. A small '#AI' or 'Generated with GPT Image 2' watermark on your OpenAI outputs keeps you compliant and transparent with your audience.
Will watermarking affect C2PA metadata from OpenAI?
Editing pixels breaks C2PA signatures because the file hash changes. This is expected behavior. If you need to preserve OpenAI's provenance signatures on GPT Image 2 output, keep a separate archival copy with the original C2PA intact.
Can I watermark multiple AI images at once?
Yes. Batch watermarking is supported. Upload a folder of GPT Image 2 or Midjourney outputs, configure the watermark once, and apply it across the entire batch. Processing runs locally in your browser.
