Redundancy and Algorithms Searching for Patterns Lossy and Lossless Compression Compressing a File Compressing a file essentially involves using compression software to reduce its size. This process can help you save disk space and make the file easier to send over the Internet. Here’s a str...
The most common types of compression algorithms are lossless and lossy. Lossless algorithms do not diminish image or document quality in the reduction process and retain all original information. Lossy algorithms can reduce overall quality but create even smaller file sizes by further compressing the ...
challenge is choosing the appropriate algorithm for the type of data being compressed. Some algorithms work better for certain types of data, while others may not be suitable. Additionally, too much compression can result in loss of quality, making it important to balance compression with quality ...
GZIP can reduce the amount of data by up to 70%. Not bad, except tests comparing compressed file sizes across different compression algorithms have shown that alternativealgorithms like Brotli outperform GZIPfor text-based assets. If this is true, why do we still rely so much on GZIP? The m...
The most popular libraries for compressing text rely on two compression algorithms, using both at the same time to achieve very high compression ratios. These two algorithms are "LZ77" and "Huffman coding." Huffman coding is quite complicated, and we won't be going into detail on that one ...
This conversion is a compression mapping. Generally, the hash value space is far less than the input space. Different inputs may be converted into the same output, and a hash value cannot be used to uniquely identify an input value. Simply put, the hash algorithm compresses ...
Gzip compression uses compression algorithms that work on website files like HTML, CSS, JavaScript, and more. When a user requests a page from your website, the algorithm sends the output back in a compressed format. Depending on data size, the compression can reduce file sizes by up to 70...

but it still abuses the sensitivity of our ears to make compression optimizations. On the whole, results are quite good—but these algorithms have to complete very quickly. They, therefore, can’t squeeze file sizes down quite as far as psychoacoustic compression types do for the same given ...
We've taken a look at both lossy and lossless compression to see how they work. Now you know how it's possible to store a file at a smaller size than its original form, and how to choose the best method for your needs.Of course, the algorithms that decide what data gets thrown out...
