What does an image's pixel width and height describe?
A Aspect ratio only
B File ownership
C Pixel dimensions
D Color temperature
Answer: C. Pixel dimensions. Pixel dimensions count the image's horizontal and vertical pixels; they do not by themselves guarantee visual quality.
How is an image's aspect ratio calculated?
A Width divided by height
B Pixels divided by file size
C Height divided by color depth
D File size divided by width
Answer: A. Width divided by height. Aspect ratio compares width with height and describes the image's shape, such as landscape or portrait.
What may happen when an image is stretched beyond its proportions?
A Colors become licensed
B Metadata becomes public
C Text gains citations
D Objects can look distorted
Answer: D. Objects can look distorted. Changing width and height unequally can distort shapes; preserving proportions avoids that effect.
Which operation removes unwanted edges while keeping the remaining pixels?
A Upscaling
B Cropping
C Color grading
D Metadata tagging
Answer: B. Cropping. Cropping trims the canvas to emphasize a subject or fit a target composition.
When preparing artwork for a square profile tile, what should be checked first?
A Square crop and safe margins
B Audio sample rate
C Document line spacing
D Database row count
Answer: A. Square crop and safe margins. A square crop should keep important subjects within safe margins so platform cropping does not cut them off.
What does image upscaling attempt to change?
A Create source permissions
B Remove every artifact
C Increase displayed pixel dimensions
D Guarantee original detail
Answer: C. Increase displayed pixel dimensions. Upscaling increases pixel dimensions, but it may synthesize or interpolate detail that was not present in the original.
Can upscaling reliably recover detail that was never captured?
A Yes, every pixel returns
B No, added detail is estimated
C Only from JPEG files
D Only when printing
Answer: B. No, added detail is estimated. Upscaling can estimate plausible detail, but it cannot guarantee recovery of information absent from the source.
Which image type stores shapes as scalable paths rather than a fixed pixel grid?
A Raster graphics
B JPEG photographs
C Bitmap scans
D Vector graphics
Answer: D. Vector graphics. Vector graphics describe shapes mathematically, so they can scale without the same pixelation as raster images.
What usually happens when a small raster icon is enlarged too far?
A It converts to vector
B It gains real detail
C Its license changes
D Edges become pixelated
Answer: D. Edges become pixelated. A raster image contains a finite pixel grid; enlarging it substantially can make edges look blocky or soft.
Which format commonly supports transparent pixels?
A PNG
B JPEG
C BMP only
D Plain text
Answer: A. PNG. PNG supports an alpha channel for transparency and is commonly used for graphics needing a transparent background.
What happens to image data when a JPEG is repeatedly saved with lossy compression?
A The file becomes vector
B Transparency is guaranteed
C Some detail may be lost
D Metadata becomes a license
Answer: C. Some detail may be lost. JPEG uses lossy compression, so repeated editing and saving can add compression artifacts or reduce detail.
Which choice best preserves a transparent background for an exported graphic?
A Flatten onto white
B Use a transparency-capable format
C Export as plain text
D Add a screenshot border
Answer: B. Use a transparency-capable format. Transparent pixels require a format and export settings that preserve alpha rather than flattening the background.
For a lightweight web image, what should an editor balance?

How does a layer mask commonly control an edit?
A Change copyright terms
B Resize the whole screen
C Generate citations
D Hide or reveal selected areas
Answer: D. Hide or reveal selected areas. A mask controls where a layer or adjustment is visible without permanently erasing the underlying pixels.
Which editing method is safer when removing a small object from a photo?
A Work on a separate layer
B Overwrite the only original
C Flatten before checking
D Delete surrounding context
Answer: A. Work on a separate layer. Using a separate layer or duplicate keeps the original available if the removal needs correction.
When a generated edit changes unintended nearby areas, what should the user inspect?
A The file name
B The selection boundary
C The browser's bookmarks
D The page footer
Answer: B. The selection boundary. Selections guide localized edits, but some tools may alter beyond the marked region; inspect the full image afterward.
Why keep an editable project file before exporting a final image?
A Guarantee model ownership
B Increase image pixels
C Remove all metadata
D Preserve layers and settings
Answer: D. Preserve layers and settings. A project file can retain layers and editable settings that a flattened export may not preserve.
Which output is most appropriate for a logo that must scale across sizes?
