Why convert Image to PDF?
Real-life documents rarely come in one format. A phone photo of a receipt is HEIC, a screenshot is PNG, an image saved from a website is WebP. This converter accepts them all and puts them into a single PDF.
Every image is decoded and placed on its own page directly in your browser. You choose the page size and margins, and the order is the order you added the files.
