Use Cases (Student & Education)
Ways students and educators use the image merger for assignments, notes, and presentations.
Combine screenshots for assignment submission
Stitch multiple screenshots into one image so you can upload a single file to Canvas/Moodle/Blackboard. Recommended: Vertical layout, spacing 0–8px, PNG for text clarity; enable Retina 2x if the LMS allows larger files.
Stitch lecture notes vertically (long image)
Merge note photos or slide screenshots into a readable long image for studying or sharing with classmates. Recommended: Vertical mode, spacing 4–8px; use Retina 2x if labels or handwriting need to stay sharp.
Lab report steps in a grid (up to 9 images)
Create a clean 2×2, 3×2, or 3×3 grid to show experiment steps, results, or process photos on one page. Recommended: Grid mode, Keep full image (no crop), uniform cell size; light compression or PNG for thin lines and labels.
Side-by-side comparisons for reports
Place two images next to each other for before/after comparisons, chart comparisons, or "method A vs method B" visuals. Recommended: Horizontal layout, same height per image, add spacing (e.g. 12–24px) for a clear divide.
Portfolio or application image layout
Arrange project screenshots into a grid so admissions or scholarship reviewers can scan your work quickly. Recommended: Grid with uniform tile size (e.g. 800×800 or 1200×1200 per cell), or Vertical with same width for a consistent strip.
Worksheet / handout visuals
Merge diagrams and examples into one image before inserting into Google Docs or slides for class materials. Recommended: Vertical or grid, light spacing; PNG to keep diagrams and text sharp; Retina 2x if exporting for full-screen slides.
Group project slide building
Combine teammates' screenshots into one image so a slide deck stays consistent and easy to format. Recommended: Grid or horizontal layout, consistent spacing; set width to ~1920px or enable Retina 2x for crisp projection.
Study summaries and cheat sheets
Merge key formulas, definitions, and diagrams into one "quick review" image for exam prep. Recommended: Vertical long image or 2×2 grid, small spacing (4–8px), PNG to keep fine text readable; avoid heavy compression.
