AudioCommon audio formats include both lossless compression formats such as FLAC and lossy formats such as MP3. Lossy compression results in the loss of small amounts of information meaning a slight decline in audio quality.
ImagesDigital cameras typically store images as compressed files automatically. Some cameras also allow raw image files to be stored that are uncompressed or slightly compressed. Depending on the speed of storage media, this can slow a camera down because raw images are extremely large. As such, storage in a lossy format such as JPEG is far more common.
Disk CompressionIt is common for data to be compressed at the operating system level. For example, all data on a storage device can be automatically compressed by an operating system. With compression, there is a tradeoff between processing speed and disk usage whereby compressed files have slower access times.
CommunicationsCompressing messages sent over networks can improve performance of tools such as web browsers or mobile apps by efficiently using available bandwidth. Data compression can also lower a user's telecom bills if they are charged by data usage.
Archive FilesArchive files allow multiple directories and files to be placed in a single file. Common archive file formats such as ZIP also compress data. Archive files are commonly used for creating backups and sharing data.
The conversion of data to a format that requires less space as measured in bits.
Conserving resources such as data storage and bandwidth.
Compression consumes computing cycles. Generally speaking, it is slower to access compressed data.Lossy compression algorithms result in the loss of information and can reduce the quality of media such as audio files and images.
