FAQ

Image to Prompt Questions

Can I convert any image to a prompt for free?

Yes. The converter is free without an account. Fair-use limits protect the shared service from automated abuse, but normal image-to-prompt work requires no credits or payment.

What image formats are supported?

Upload a JPG, PNG, or WebP image up to 10MB. A clear image with one main composition usually produces a more useful prompt.

Which AI model should I choose?

Choose General for portable visual language. Select a named model when you plan to paste the result into that model and want its typical wording.

Does Wenimg store the image I upload?

The converter sends the image for analysis and does not add it to your Wenimg files or public prompt library. Avoid uploading confidential or highly sensitive material.
