TIFF (Tagged Image File Format) files are typically lossless, meaning they preserve all the original image data without any compression that would degrade quality. However, TIFF can also support lossy compression methods, depending on the settings used when saving the file. This flexibility allows TIFF files to be used in various applications, from high-quality print graphics to more space-efficient storage. Overall, the lossless nature of TIFF is one of its key advantages, especially in professional imaging workflows.

The main difference between JPG and TIFF file formats is the way they store image data. JPG files use lossy compression, which reduces file size but can result in some loss of image quality. TIFF files, on the other hand, use lossless compression, which preserves image quality but results in larger file sizes.
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.

PNG and TIFF are both image file formats, but they differ in terms of image quality and compression. PNG files are typically smaller in size and use lossless compression, meaning they retain high image quality without losing any data. On the other hand, TIFF files can support both lossless and lossy compression, allowing for higher quality images but also larger file sizes. Ultimately, PNG is better for web use and images with transparency, while TIFF is preferred for high-quality printing and professional photography.
File compression uses software algorithms to reduce file size by reducing the bit-rate of a file. Lossy compression takes it a bit further and lowers the quality of thr file to make it even smaller. Lossy compression is commonly used for media files, but would not be appropriate for other types of files.
