Sign PDF: upload a PDF, then draw your signature with a mouse or finger, or type your name in a handwriting font. Drag the signature to any position on the page, resize it, and it is stamped onto the file. Image to PDF: add JPG, PNG or WebP images, reorder the thumbnails, choose A4, Letter or fit-to-image pages, and get a single PDF back.
