Why photos lose quality when sent via WhatsApp or social media

The article explains why photos lose quality when sent through messaging apps or uploaded to social networks, primarily due to compression processes applied by these platforms.

The article addresses a common issue experienced by smartphone users: the loss of photo quality when transferring images through messaging applications or uploading them to social networks. Initially, images appear vibrant and sharp on the device's gallery, but upon sharing, they often appear washed out and less detailed. While users typically blame the quality of their phone's camera, the problem usually lies in the processes that images undergo after being taken.

Images viewed on smartphones are not raw files but rather undergo an automatic processing sequence that enhances their appearance. This includes High Dynamic Range (HDR), tone adjustment, noise reduction, sharpening, white balance, and color management. These optimizations are specifically tailored for the display screen of the device, which means that the refined quality does not necessarily transfer when the image leaves that specific environment.

The primary culprit for quality degradation is the compression algorithms applied by messaging apps and social media platforms. These applications compress images to facilitate quicker sharing and reduce data usage, which often results in a noticeable loss of quality. Understanding this process can help users manage their image expectations better when sharing photos digitally and adjust their settings or methods for sharing high-quality images.
