Lossless compression recreates a compressed file as an identical match to its original form. While lossy compression can't be used to compress anything that needs to be reproduced exactly.

Difference between lossless and lossy compression?
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.
What is difference between lossy and lose less data comprasion?
Lossy= You lose somedata Lossless= You dont
Is a PICT a type of Lossy or Lossless compression file?
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.
What is one type of lossy audio compression file?
MP3
Are PNG files lossy or lossless?
Lossless. Compression techniques do not remove detail from the image.
What is it called when compression data some of the data is lost yet can represent the original close enough?
When compressed data that is subsequently decompressed does not exactly match the original, yet it is considered close enough to the original to be usable, that algorithm is called a lossy compression. Contrast that with lossless compression, where the decompressed version exactly matches the original. Lossy compression is useful in audio and video, where exactness is not critical, while lossless compression is useful in data streams that must be preserved exactly. The lossy compression algorithm often results in more compact compressed results.
What file formats use lossy compression?
There are a ton. Most things that use wavelets to encode the data fall into this category. Often the same file format and "extension" can have multiple actual encoding mechanisms on the inside, so it might sometimes have lossy compression and sometimes not. Examples of file formats with lossy compression include mp3,jpeg and mpeg. Container formats like avi, and wma sometimes do and sometimes don't.
What are the advantages and disadvantages of lossless and lossy compression?
Lossless compression results in a closer representation of the original media, and thus a higher quality end product. The disadvantage is that the resulting file will be larger than if you had used a lossy compression format. Lossy compression can give you a smaller file size, but the resulting end product may be in some ways inferior to the original.
Is GIF lossless or lossy?
GIF is a lossless compression introduced by CompuServe in 1987 using Lempel-Ziv-Welch (LZW) lossless data compression.
Why some bulk message sending software encountering spamming and sending failed problems?
Basically, mobile communication use compression techniques. Two types of compression techniques are there. they are: 1. lossy compression 2. lossless compression. While the user send an SMS, copmression technique is applied at the transmitter section and decompression technique is applied at the receiver. These compression techniques were takes place automatically. 1. In lossy compression, some data may lost at the receiver while performing decompression. 2. In lossless compression, the transmitted data is received without any loss at the receiver. Due to lossy compression only, u may have some problems at the receiver side such as "some text missing". etc.
Is TIFF lossy or lossless?
lossless
TIFF files can be edited and resaved without compression loss?
Yes, provided that they are not using a lossy compression like jpeg to store the image data. This should be configurable in the save dialogue.
