A PNG file contains a single image in an extensible structure of chunks, encoding the basic pixels and other information such as textual comments and integrity checks documented in RFC 2083. [7] PNG files have the ".png" file extension and the "image/png" MIME media type. [8] PNG was published as an informational RFC 2083 in March 1997 and as ...

Including proprietary types, there are hundreds of image file types. The PNG, JPEG, and GIF formats are most often used to display images on the Internet. Some of these graphic formats are listed and briefly described below, separated into the two main families of graphics: raster and vector.
JPEG. JPEG ( / ˈdʒeɪpɛɡ / JAY-peg, short for Joint Photographic Experts Group) [2] is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality.
If you do not have an original file but only a JPEG that really should be a PNG, do not simply save the JPEG as PNG because this will result in an even larger file. There is a nice tutorial at Wikipedia:How to reduce colors for saving a JPEG as PNG. Use SVG over PNG
JPEG XL – an image file format developed since 2019 (standardization completed since 2022) and based on Google PIK [Wikidata] and Cloudinary FLIF (itself based upon FUIF [Wikidata]) claiming to outperform PNG, WebP, BPG and JPEG 2000 for lossless encoding at least
Format conversion: convert an image from one format to another (e.g. PNG to JPEG). Transform: resize, rotate, crop, flip or trim an image. (Applies these without generation loss on JPEG files, where possible.) Transparency: render portions of an image invisible. Draw: add shapes or text to an image. Decorate: add a border or frame to an image.

The JPEG File Interchange Format (JFIF) is an image file format standard published as ITU-T Recommendation T.871 and ISO/IEC 10918-5. It defines supplementary specifications for the container format that contains the image data encoded with the JPEG algorithm.
Once it looks correct, save the image as a PNG. Then, to reduce file size, run it through a program like ImageMagick that supports 8-bit PNGs with alpha transparency, in order to remove any unnecessary colors. (This may or may not be done automatically by a PNG optimizer, as well.)
