Thus, a representation that compresses the storage size of a file from 10 MB to 2 MB yields a space saving of 1 - 2/10 = 0.8, often notated as a percentage, 80%. For signals of indefinite size, such as streaming audio and video, the compression ratio is defined in terms of uncompressed and compressed data rates instead of data sizes:
OneDrive can use geo-location data for photos uploaded to the service, and will automatically display a map of the tagged location. OneDrive also allows users to tag people in photos uploaded via the web interface or via Windows Photo Gallery. OneDrive also has support for the UWP app, Microsoft Photos.
The compression ratio (that is, the size of the compressed file compared to that of the uncompressed file) of lossy video codecs is nearly always far superior to that of the audio and still-image equivalents. Video can be compressed immensely (e.g., 100:1) with little visible quality loss
Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission. Algorithms may take advantage of visual perception and the statistical properties of image data to provide superior results compared with generic data compression methods which are used for other digital data.

The service allows you to share files and also have audio or video calls with its secure chat. ... OneDrive, Google Drive and Google Photos to back up files. The free version comes with a robust ...
Images, audio and video files must be uploaded into Wikipedia using the "Upload file" link on the left-hand navigation bar. Only logged in users can upload files. Once a file is uploaded, other pages can include or link to the file. Uploaded files are given the "File:" prefix by the system, and each one has an image description page.
JPEG greatly reduces the amount of data required to represent an image at the cost of a relatively small reduction in image quality and has become the most widely used image file format. [36] [37] Its highly efficient DCT-based compression algorithm was largely responsible for the wide proliferation of digital images and digital photos. [38]
File size is a measure of how much data a computer file contains or how much storage space it is allocated. Typically, file size is expressed in units based on byte. A large value is often expressed with a metric prefix (as in megabyte and gigabyte) or a binary prefix (as in mebibyte and gibibyte). [1]
