GIF is a lossless compression introduced by CompuServe in 1987 using Lempel-Ziv-Welch (LZW) lossless data compression.
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.
The areas of compression are lossless compression and lossy compression. Lossless compression reduces the file size without sacrificing any data quality, while lossy compression reduces the file size by discarding some data, which may lead to a decrease in quality.
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.
