Picture compression is the practice of utilizing certain encoding techniques to encode digital image information using fewer bits than an unencoded representation would need.
JPEG, the most prevalent compression technique, has a tendency to blur lines, especially at low resolutions. Lossless image compression algorithms, on the other hand, keep the image's original quality while compressing it less efficiently. TIFF, GIF, and PNG are some examples.
While JPEG compression can substantially decrease the size of an image file, it can also degrade the image's quality - and there may be no way to recover if you're not cautious. As a result, we recommend that you save your photos in a lossless format like TIFF.
Lossless and lossy image compression algorithms are the two types of picture compression algorithms. Lossless compression methods shrink files while keeping an exact duplicate of the uncompressed picture. Lossless compression produces bigger files than lossy compression in most cases, but not always.
Lossless compression is a type of data compression in which the original data may be completely reconstructed from the compressed data. Some image file formats, such as PNG and GIF, solely employ lossless compression, but others, such as TIFF and MNG, can use both lossless and lossy compression.
