JPEG vs TIFF
JPEG/JPG is the standard file format of most of consumer-quality
digital cameras and is supported by most imaging
software. JPEG offers efficient file sizes for uploading/posting
on websites or emailing as attachments.
JPEG uses lossy compression, meaning some image data is
lost when the file is compressed and then uncompressed.
The amount of compression can vary, with more
compression meaning more data loss but resulting in a smaller
file. JPEG, like TIFF, is a good bet for a long
term archival format.
Uncompressed (lossless) TIFF is the standard for most
commercial digital photo printing needs. TIFF is an
excellent choice for archiving images when file size is
not a consideration as uncompressed TIFF files are larger
