What is the difference between lossy and lossless images? After compression, lossy files are smaller in size than lossless ones. However, the quality is usually lower than it would be if you’d used lossless compression. That said, it may not be too noticeable, depending on how you are vie...
To ensure you’re optimizing your images correctly, it helps to understand the difference between lossy vs lossless compression.In this post, we’ll start by explaining both lossy and lossless compression. Then we’ll discuss when to use lossy vs lossless compression on your WordPress site....
Lossy compression algorithms often result ingreater reductionsin file size. It’s often the case that the human eye cannot distinguish between lossless and lossy compression. Lossy image compression offers the best compression ratios with good enough approximations. On the other hand, lossless compressio...

As previously mentioned, one of the main benefits of Lossless compression is being able to keep and restore every single bit of data that was within the file after it is uncompressed.This is in contrast to Lossy compression, where metadata is not saved during the compression process and results...
After trying every possible maneuver to squeeze it though, it becomes clear that it’s better to disassemble it and move the pieces through the door. Once inside the room we can reassemble the bed and get comfy. And this is how lossless compression works! Using another part of same the ...
The first instructions generate a binary bitmap indicating a high or low density of the solid regions and a binary bitmask indicating whether recorder elements belong to a solid or screened region. The bitmap and bitmask are preferentially compressed by a lossless compression method. The second ...

Image compression may be lossy or lossless. Lossless compression is preferred for archival purpose & often used for medical imaging, technical drawings, clipart or comics. Lossy compression methods especially used at bit rate i.e. suitable for natural images such as photographs. The lossy ...
Modern applications, in addition to high compression ratio, also demand for efficient encoding and decoding processes, so that computational constraint of many real-time applications is satisfied. Two widely used spatial domain compression techniques are discrete wavelet transform and multilevel block ...
