Common questions
Is this a different account from MD Converter?
No. Sign in once. Credits, checkout, and your profile are shared. MD Publisher is a separate product URL with the same account.
Does generating a preview spend a credit?
No. Filling SEO fields and the watermarked OG preview are free. Downloading merged Markdown or a clean PNG spends one credit each.
Will this overwrite my front matter?
Only matching keys are replaced. Author, date, and other fields you already have stay in the file.
Is my Markdown stored?
Uploads are temporary, the same as MD Converter. We do not keep a library of your posts.
