they are lossless...
Lossless. Compression techniques do not remove detail from the image.

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.

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.

GIF is a lossless compression introduced by CompuServe in 1987 using Lempel-Ziv-Welch (LZW) lossless data compression.
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.
No, PDF (Portable Document Format) is not inherently lossy. It is a versatile file format that can contain text, images, and vector graphics, and it supports both lossless and lossy compression methods depending on how the content is encoded. For example, images within a PDF can be saved in a lossy format (like JPEG) or a lossless format (like PNG). The overall quality depends on the settings chosen during the PDF creation process.
