You don't need special software to turn JPG or PNG images into a PDF on Linux. FernPDF runs entirely in Firefox or Chrome on Linux: open the tool, drop your file, download the result. Photos of IDs, receipts and forms stay on your device, the safest way to PDF anything personal.
No hunting for the right CLI flags or building tools from source. A browser is the only dependency, on any distribution.
