One strong picture beats a paragraph, but a blurry clip-art image stretched across a slide does the opposite. A few techniques make images look intentional.

Find images

  • Insert › Pictures › Stock Images (Microsoft 365): free photos, icons, illustrations, no attribution worries.
  • Insert › Icons: simple line icons that recolour to match your theme.
  • Your own photos: real products and real office pictures beat stock for credibility.
⚠️ Images from a web search are usually copyrighted. Use stock libraries, your own photos, or images you have rights to.

Crop and fill

  • Picture Format › Crop: drag black handles to trim; drag the picture to reposition inside the crop.
  • Crop › Fill makes the picture fill a placeholder without stretching.
  • Crop › Crop to Shape for circles (team photos) and rounded rectangles.
  • Full-bleed: a photo covering the whole slide with a short title on a semi-transparent shape is the most striking layout there is.

Remove background

Picture Format › Remove Background cuts out a product from a plain background. Mark areas to keep or remove, then Keep Changes.

Designer

Design › Designer (Microsoft 365) suggests layouts when you add pictures or lists. Pick one that fits, or close the pane. Good for quick starts; still check text size and that it matches your other slides.

Line things up

  • Smart guides (red dashed lines) appear as you drag; snap to them.
  • Select several objects › Shape Format › Align › Align Top / Distribute Horizontally.
  • Group (Ctrl+G) keeps icons and labels together.
💡 Icons in one style and one colour look professional; a mix of photo, cartoon and 3D clip art looks amateur.

Keep file size small

Picture Format › Compress Pictures, untick “Apply only to this picture”, choose Web (150 ppi), tick Delete cropped areas. Decks often shrink from 80 MB to 8 MB.

Alt text

Right-click › View Alt Text: a one-line description for screen readers. Mark purely decorative images as decorative.

Where beginners go wrong

Mistake Fix
Stretched, distorted pictures Resize from corners; Crop › Fill
Low-resolution images projected large Use larger originals
Text over a busy photo Add a dark semi-transparent shape behind the text
Huge deck that won’t email Compress Pictures
