# Images To Pdf — MCP tool `findutils:images_to_pdf`

Combine JPG and PNG images into a single PDF, one image per page, in the order given. Choose a fixed A4 or Letter sheet with the image fitted inside it and centred, or "fit" for a page exactly the size of each image. Images are embedded as they are and never re-encoded, so nothing is lost. Input images and the output PDF are base64.
