Image to PDF takes multiple pictures and stitches them into one PDF, in the order you add them, so you end up with a single file to attach or archive. You choose how each picture becomes a page. Fit to A4 page, the default, scales every image down to fit a standard portrait or landscape sheet and centers it, which suits anything you might print. Match image size keeps each page exactly the pixel dimensions of its source photo, useful when you care about the image staying at its native resolution rather than a fixed paper size. A tall photo naturally becomes a portrait page and a wide one a landscape page under the fit option, so rotation is rarely needed first. Formats accepted include jpg, png, webp, gif, bmp, and tiff, and you can add as many images as the document needs. Transparent backgrounds are filled in white rather than left blank, since a PDF page has no concept of transparency, so check a logo with a see-through background before relying on this. Uploaded files sit on the servers only briefly and are cleared automatically within the hour. ## How to use the Image to PDF tool 1. Add your JPG, JPEG, PNG, WEBP, GIF, BMP, TIFF files: drag & drop or click to browse; you can add several. 2. Set your options: Page size. 3.
