How to convert JPG or PNG images to PDF
Phone photos and screenshots are awkward to email as a dozen files. A single PDF is often what a form or a person actually wants.
Pick the matching converter
Use JPG to PDF for camera photos. Use PNG to PDF for screenshots and graphics with transparency. The PNG tool paints a white page first so transparent pixels do not become black in some readers.
How pages are built
Each image becomes one A4 page, centered and scaled to fit with a margin. Extremely wide images letterbox. This is a predictable print size, not a “page exactly as many pixels as the photo” mode.
Compress first if the PDF is huge
A 12-megapixel burst will make a heavy PDF. Run Image Compressor first if the recipient has a size cap. Compression is lossy JPEG — that is a quality trade, not a hidden watermark.
Questions
Can I mix JPG and PNG in one step?+
Convert each type, then merge the PDFs. The dedicated converters keep JPEG and PNG handling explicit.
