Microsoft Designer turns prompts into images, social posts and graphics, and pairs the results with templates for resizing and remixing across formats. It is free to use with a Microsoft account – a daily batch of boost credits speeds up generation – and sits naturally next to Microsoft 365 apps many offices already run.
Paid capacity arrives indirectly: Microsoft 365 Personal ($9.99 per month) and Family ($12.99) include larger Designer credit allowances alongside Word, Excel and Copilot, so households and workplaces that already subscribe effectively get premium Designer for nothing. Export options and template breadth make it the pragmatic free pick for social content, though fine art direction still belongs to Midjourney or Firefly.
