To convert JPG images to a PDF, open a browser-based image-to-PDF tool, add your images, drag them into order — each image becomes one page — and download the PDF. It runs on your device, so the images are never uploaded. PNGs are embedded losslessly and JPGs are embedded as-is, so images are not re-compressed, with no sign-up and no watermark.
Turning photos or scans into a single PDF is how you send a set of receipts, assemble an ID’s front and back, or bundle a photographed document into one shareable file. Here is how to do it privately, and what happens to image quality.
The images are read and combined on your device, so nothing is uploaded.
No. PNGs are embedded losslessly and JPGs are embedded as-is, so images are not re-compressed or degraded. Each PDF page is sized to its image, which means mixed image sizes produce mixed page sizes. Inputs are JPG and PNG; other formats such as HEIC, TIFF, or GIF need converting first.

Large or numerous images are limited only by your device’s memory, since nothing is uploaded. If the images are photos of documents that you want to be searchable, create the PDF here first, then run OCR to add a selectable text layer.
