file compression
Making files smaller
File compression is reducing the size of digital files by encoding their data more efficiently.
This saves storage space and speeds up file transfers.
Compression may be lossless, preserving all original data when decompressed, or lossy, discarding some data permanently—acceptable for images and audio where slight quality loss goes unnoticed.
