What Gets Lost During .MP3 And .MP4 Compression: The Difference Between Lossy and Lossless Formats

.AVI - Audio Video InterleavedAVI is a multimedia container format introduced by Microsoft. When video data is not compressed, the video size is large. You need a codec (coding and decoding) to compresses the video.Most video codecs are lossy. When used, some image details are lost, like Microsoft Video 1(MSVC) or H264. On the other hand, Wisdom-Soft Lossless Codec (WIS1) is a zero-loss codec, by which no image detail is lost during the compression..MP4 - MPEG-4MP4 is a commonly used video format for downloading and streaming videos from the internet. It is compatible with most online video platforms. However, the video quality is not the highest..GIF - Animated GIFA GIF is a 256 color format for image files that supports both static and animated images. AutoScreenRecorer 5 can convert your video to an animated GIF file..MKV - Matroska VideoMKV supports unlimited video, audio, and subtitle tracks. They're similar to MOV and AVI files..MOV - Apple QuickTime MovieMOV is an MPEG-4 video container file format used in Apple's Quicktime program and iPhones..FLV - Flash Video FLV file extension is a file that uses Adobe Flash Player over the internet..OGG - OGG formatOpen standard container format maintained by the Xiph.org..MPG - VCD MPEG-2 formatIt offers small files, easy to download and transfer. In conversion to a VCD, NTSC is mainly used in North America. PAL is mainly used in Europe, Asia, and Australia..MP3 - MPEG-1 Audio Layer 3A data compression format for encoding digital audio, most commonly music..WAV - Waveform AudioAn audio file format standard, developed by IBM and Microsoft, for storing an audio bitstream on PCs.

Download Zip

The JPEG (Joint Photographic Experts Group) format is a compressed image file that is commonly used to store digital photos. The JPEG format uses lossy compression, which means that some of the data from each image are lost during compression.

For example, ZIP files can use either lossless or lossy compression on the data that is stored in the ZIP file. This means that the size of the ZIP file can be reduced, but the quality of the data within the ZIP file will not be affected. RAR files use a lossless compression format, which means that no data is lost during compression. This results in a smaller file size, but the images and other files within the RAR file will not be blurred or pixeled.

Lossy file formats are those where the data is compressed, or lost, during the encoding process. Lossless file formats do not lose data during encoding. For this reason, lossless formats are often larger and more expensive to store. However, for the purposes of long-term retention and preservation, lossless formats are preferred. Lossy file formats are more suitable for short-term access purposes. TIFF is an example of a lossless image format, whereas JPEG is a lossy image format, because image data is irretrievably lost due to compression.
