Sample ICDL Image Editing Practice Questions

Try these sample questions to test your ICDL Image Editing exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 120+ question experience with AI tutoring.

1A Transition Year student in Cork exports a school poster from GIMP. The file is built from a fixed grid of coloured squares that blur when enlarged. Which term describes this image type?

A.Raster (bitmap) graphic

B.Vector graphic

C.Procedural texture map

D.Lossless audio waveform

Explanation: Raster images store colour in a pixel grid. Enlarging them spreads the same pixels over a larger area, which causes visible blockiness or blur. ICDL syllabus task 1.2.1 distinguishes raster from vector formats.

2Your ICS Skills trainer asks you to prepare a county crest that must print sharply from a business card to a GAA banner. Which format family is most appropriate for the master artwork?

A.JPEG photograph of a hand-drawn sketch

B.SVG or EPS vector artwork

C.Animated GIF with 256 colours

D.Uncompressed BMP screenshot

Explanation: Vector formats such as SVG and EPS describe shapes mathematically, so they scale to any size without losing edge sharpness. The syllabus lists SVG and EPS as common vector formats suitable for logos and line art.

3In ICDL Image Editing, what does resolution measure?

A.The brightness range between black and white

B.The total number of layers in a project file

C.How many pixels fit within a given unit of length

D.The number of undo steps stored in memory

Explanation: Resolution expresses pixel density, typically in pixels per inch (ppi) or pixels per centimetre. Higher resolution packs more pixels into the same physical area, preserving detail when printed.

4A photo for the school yearbook must print at 15 cm wide. The image is 1800 pixels wide. What is the effective resolution in pixels per centimetre?

A.60 ppcm

B.300 ppcm

C.180 ppcm

D.120 ppcm

Explanation: Divide pixel width by physical width: 1800 ÷ 15 = 120 pixels per centimetre. Understanding this relationship helps you judge whether an image will look sharp at a given print size.

5Which statement best describes lossy compression?

A.Some image data is permanently discarded to reduce file size

B.File size shrinks while every original pixel value is preserved exactly

C.Only the canvas border pixels are removed

D.The image is converted to a vector path automatically

Explanation: Lossy algorithms such as JPEG compression remove data the eye is less likely to notice. Each re-save can compound quality loss, which is why ICDL guidance favours lossless working formats during editing.

6You archive a master scan at an Irish community centre before any retouching. Which format preserves all pixel data without compression artefacts?

A.JPEG at quality 60

B.TIFF with lossless settings

C.GIF with dithering

D.JPEG at quality 10

Explanation: TIFF supports lossless storage, making it suitable for archival masters. JPEG and heavily optimised GIF introduce or accentuate compression artefacts unsuitable for a pristine archive.

7A web designer in Dublin needs a logo with a transparent background for a parish website. Which format is the best standard choice?

A.BMP uncompressed

B.JPEG baseline

C.PNG with alpha transparency

D.RAW camera file

Explanation: PNG supports alpha-channel transparency and lossless compression, so the logo can sit over any page background without a white box. JPEG does not support transparency.

8Before sitting the ICDL Image Editing test, you save ongoing work with editable layers in GIMP. Which native format should you choose?

A.Plain text CSV

B.JPEG

C.GIF animation

D.XCF

Explanation: XCF is GIMP's native layered format. The syllabus recognises proprietary editing formats such as XCF, PSD, and PSP that preserve layers for continued work.

9Which colour model combines red, green, and blue light for screens and monitors?

A.RGB

B.CMYK

C.Grayscale only

D.Indexed 16-colour palette

Explanation: RGB is an additive model: red, green, and blue light combine to produce on-screen colours. ICDL syllabus task 1.3.1 lists RGB among common colour models.

10A brochure for a Limerick print shop will be output on a four-colour press. Which colour model should the final flattened image use?

A.RGB

B.CMYK

C.HSB only

D.Bitmap 1-bit

Explanation: Commercial offset printing mixes cyan, magenta, yellow, and black inks (CMYK). Converting RGB screen colours to CMYK before print reduces unexpected colour shifts.

ICDL Image Editing Study Tips from Top Performers

1Download the official Image Editing Syllabus 2.0 PDF from icdl.org and tick off each task item as you practise in GIMP, Photoshop, or your centre's application.

2Work through ICDL sample part-tests to see how theory MCQs are phrased, then use this bank for broader category coverage.

3Practise the difference between canvas size (adds workspace) and image size (scales pixel content) before your test.

4Master selection modifiers: Shift to add to a selection, Alt/Option to subtract, and experiment with feathering for smooth cut-outs.

5Build a three-layer composite — background, subject, text — to practise layer order, opacity, and flattening before JPEG export.

6Take timed 45-minute practice sessions with 36 questions to simulate the official test length and pace.
