What is image compression:
Minimising the size in bytes of a graphic file with out degrading the quality of image to unacceptable level.
Minimising the size in bytes of a graphic file with out degrading the quality of image to unacceptable level.
Types of image file compression:
Lossless:
Lossless:
Allows original data to be perfectly reconstructed from the compressed data.
Lossy:
Lossy:
Irreversible compresssion.
Reduced data size for storage, handling and transmitting content.
Why do we compress images:
Fairly small file size for the quality that it displays.
How do compressed file work:
No information is lost.
Win zip are based on lossless compression.
Redundant information compress (zip) file.
Restores it uncompress (unzip) file.
When to use which format:
Use JPG for photos.
Use GIF for simple drawings, an image and transparent background.
Use PNG for screenshots automatically computers save it as PNG.
