Scaling means resizing an image — making it larger or smaller.
Why is it important that every pixel is visible?
Because visible pixels preserve the photo’s sharpness and detail, making the image look clear and professional.
Why might someone prefer lossy compression even if it reduces image quality?
Because lossy compression creates smaller files, which are faster to upload, download, or send by email.
What is a “thumbnail-sized photo”?
A very small image, like a preview picture or icon version of a larger photo.
What’s the difference between a “vector graphic” and a “raster graphic”?

Which type of compression keeps the full quality of a photo?
Lossless compression keeps the full quality of a photo.
What type of compression can make photos blurry?
Lossy compression can make photos blurry because it removes some data from the image.
What does it mean to “sharpen” a photo?
It means using a tool to increase the contrast and clarity of edges in the image to make it look clearer.
How do you think resizing affects image quality in design projects?
If you enlarge an image too much, it becomes pixelated or blurry; reducing it too much can make details hard to see.
