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.
Tiffs typically produce larger files because their compression format maintains all the image data. Jpegs are "lossy," meaning their compression format works by discarding some of the data, reducing the number of colors stored in the image.
The amount of minutes in a video file cannot be determined by it's file size. The file size of the video is determined not only by it's length, but also by the size of its resolution, the audio bitrate, the type and amount of compression amount used for audio and video, the type of format it's rendered as, and possibly other factors.
a mp3 play*s music files and a* mp4 plays music and video only some companies can say mp4 but others say mp3 with videomp3 is an audio file while mp4 is both audio and video.
I don't know a lot about how this works, but compressing a file is saving a file in a way that makes it smaller in size. This is useful for saving space on your computer or storage device, and for sending files. As far as I know, there are two types of compression, lossy & lossless. Lossy compression removes "unnecessary" information as it compresses the file, which can be fine, but can also create problems depending on the type of file & how you will be using it. With some files, such as graphic files, you need to be careful especially if you are going to be making changes and saving it again. For example, if you use photo editing software and save as a low quality jpeg (aka jpg) file, then repeatedly open the file, make changes & save it each time in the same format, you will see a reduction in the quality of the image. On the other hand, if you aren't going to be making changes to the file and you are only going to be viewing the image on screen, low quality jpg format is fine. Lossless compression does not remove information from the file, so you can safely save and re-edit your file as much as you like, but you can't reduce the file as small as lossy compression.

Any type of compression will ideally reduce the size of an image. There are two types of compression which describe how they affect images:"Lossy" compressionThis type of compression reduces the size of the image by removing some data from it. This generally cause, effect the quality of the image, which mean it will reduce your image quality."Lossless" compressionThis type of compression reduces the size of the image by changing the way in which the data is stored. Therefore this type of compression will make no changes in your image.

Microsoft's audio file type is .wma (Windows Media Audio). However most Microsoft platforms will support other popular types of audio files.

Which compression type using in BMP image file? The BMP image file normally doesn't use any compression at all. This is why usually they are large files and are not used on the web.
Compression ratio simply means the difference in size of the original vs compressed unit. Compression ratio is a commonly used term for internal combustion engine piston/cylinder compression and file compression. Ratios differ depending on the type of engine or the type of file being compressed. In file compression, 7zip has the highest compression ratio.
