Turn PNG graphics — including designs with transparency — into PDF pages without sending files to a server.
The converter aims to preserve PNG detail and color. Some PDF viewers composite transparent regions against white; check the preview in your preferred reader if exact alpha matters.
Prefer PNG for screenshots, UI mockups, and graphics with sharp edges or transparency. Prefer JPG for large photographic sets when smaller file size matters more than lossless detail.
Very large PNGs can stress mobile memory. Try fewer files at once, or downscale oversized images in the Image Converter before building the PDF.
