PNG file format is better than JPEG for image quality because it supports lossless compression, which preserves image details without sacrificing quality. However, PNG files are larger in size compared to JPEG files, which use lossy compression.

The most common file extensions for image files are: GIF: Old, can be animated, 8-bit color JPEG/JPG: High compression rate, No transparency, lossy PNG: Can be transparent, lossless
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 main difference between using PNG and JPG formats for printing is the way they handle image compression. PNG files are lossless, meaning they retain all image data and quality, making them ideal for printing high-quality images. JPG files, on the other hand, are lossy and compress image data, which can result in a loss of quality when printed. Therefore, for printing purposes, it is generally recommended to use PNG files for better image quality.

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.
