It really depends on the image.
JPEG is an excellent format to use for photographic images that include a full range of tones and colors. It is not at its best when used for simple line art.
SVG is good for line art but can't do photographic images other than being a container for a JPEG or PNG. It is a vector format (SVG = Small Vector Graphic) and not a bitmap format.
PNG is an extremely plastic format and as a result most (>90%) of the info you'll find on this site is inaccurate due to omissions in the discussion (generally, things are claimed for the PNG format overall when they only apply to a few of the many ways a PNG can be built). PNG can use a wide range of bit depths and can use a variety of compression methods (lossy JPEG-like, lossless, and none). As a result, if you use the right tool to create the PNG and make the right choices in generating the final PNG it can be as good as any other bitmat format for almost any use. At low bit depths and with a lossless or no compression it can deliver compact clean line art in much the same was as the GIF format can. At high bit depths (e.g. 24bit) it can do excellent photographic images which can be compressed rather well if you choose the compression settings wisely.
