i2PDF uploads your files to build the PDF: its own page says files are uploaded and automatically deleted after 30 minutes. A browser-based image to PDF tool assembles the document on your own device, so the pictures are never uploaded at all.
i2PDF is a convenient image to PDF tool, and its own copy explains that your files are uploaded and are automatically deleted after 30 minutes. Combining photos into a PDF is something a browser can do entirely on its own, so a client-side converter reads your JPG and PNG images, packs them into a single PDF in the browser's memory, and hands you the finished file with no upload and nothing to delete.
Local assembly is the safer choice because photos turned into PDFs are so often sensitive: receipts, IDs, signed forms and medical paperwork. You add the images, drag them into the order you want, and download one clean PDF, with no watermark, no account, and the pictures never leaving your device.
