JPEG is lossy because it takes away the gema blue and gema red.
Yet for our eyes it might look lossless because our eyes are not sensitive to the parts that JPEG takes away.
GIF is a lossless compression introduced by CompuServe in 1987 using Lempel-Ziv-Welch (LZW) lossless data compression.
PNGs are lossless, JPGs are not.

Lossless. Compression techniques do not remove detail from the image.

These are different file formats. jpeg uses a lossy compression algorithm. Tiff can use a lossless algorithm (the compression algorithithm can be defined for each image).TIFF is a flexible, adaptable file format for handling images and data within a single file, by including the header tags (size, definition, image-data arrangement, applied image compression) defining the image's geometry. For example, a TIFF file can be a container holding compressed (lossy) JPEG and (lossless) PackBits compressed images. A TIFF file also can include a vector-based Clipping path (outlines, croppings, image frames). The ability to store image data in a lossless format makes a TIFF file a useful image archive, because, unlike standard JPEG files, a TIFF file using lossless compression (or none) may be edited and re-saved without losing image quality. This is not the case when using the TIFF as a container holding compressed JPEG. Other TIFF options are layers and pages, neither are supported by JPEG.
Pict files can use 2 different forms of compression. 1- RLE Compression (the default) is lossless. 2- JPEG compression (only on some systems/graphics programmes) is lossy.
TIFF is a lossless compression. JPEG throws away data to reduce file sizes.
No, AVI is not a lossless format. AVI (Audio Video Interleave) is a container format that can contain audio and video data compressed using various codecs, some of which may be lossy.
