Why do images that get repeatedly copy get have their quality degrade over time?
In: 1
Just copying a file locally on a computer won’t degrade it. However when uploading to photo sites/youtube/etc, the sites usually will re-encode the image/video (to save space). JPEG is called ‘lossy’ encoding where it throws information about the image away. Normally you don’t notice this for a new image, but if you keep loading/saving a JPEG file repeatedly it loses more information and gets blocky looking.
