Google Ads Image Requirements: Sizes, Formats, Logos & Optimization Guide (2026)

What are the exact Google Ads image sizes, formats, and logo specifications? This is Step-by-step optimization guide with real use cases and conversion workflows.

Image assets are no longer optional in Google Ads. In Performance Max, Demand Gen, Display, and App campaigns, high-quality visuals directly influence:

  • Click-through rate (CTR)
  • Conversion rate
  • Ad strength score

Google’s internal documentation consistently shows that adding image assets can significantly improve engagement compared to text-only ads. More asset variety also increases eligibility across placements (Gmail, Discover, YouTube, Display Network).

From practical campaign experience, the biggest performance gains often come not from new keywords but from properly formatted image assets that unlock more inventory.

Google Ads Image Asset Format Requirements

According to official Google Ads asset specifications:

Supported formats

  • JPG
  • PNG

Maximum file size

  • 5 MB per image

Aspect ratios required

  • 1.91:1 (landscape)
  • 1:1 (square)

Recommended resolutions

  • Landscape: 1200 × 628 px
  • Square: 1200 × 1200 px

Minimum resolutions

  • Landscape: 600 × 314 px
  • Square: 300 × 300 px

These are not just technical constraints. Ads with the recommended 1200px sizes consistently look sharper on high-density mobile screens, which now account for well over 60% of Google Ads traffic globally.

If your original creative is the wrong size, you can resize it without quality loss using the appropriate tool at https://plomz.com/resize-image

Logo Size for Google Ads

Logos are separate from marketing images and must follow stricter rules.

Square logo

  • Recommended: 1200 × 1200 px
  • Minimum: 128 × 128 px
  • Aspect ratio: 1:1

Landscape logo

  • Recommended: 1200 × 300 px
  • Aspect ratio: 4:1

A transparent PNG is strongly recommended for logos. If your logo has a background, remove it before uploading using the background removal tool on https://plomz.com/remove-background

This ensures proper rendering across light and dark placements.

Image Sizes for Different Campaign Types

Performance Max

You should upload at least:

  • 1 square image
  • 1 landscape image
  • 1 square logo
  • 1 landscape logo

Advertisers who provide the full asset set typically achieve higher ad strength ratings, which correlates with better delivery.

Demand Gen & Discovery

These are highly visual placements. The most used sizes are:

  • 1200 × 1200
  • 1200 × 628
  • 960 × 1200 (portrait)

Portrait images are optional but increasingly valuable because they occupy more mobile screen space.

Display Ads (Responsive)

Responsive display ads automatically scale assets, but high-resolution source images are critical for maintaining clarity across formats.

When and Why You Need to Convert or Resize Images

Real-world workflows where conversion is required:

  • A designer exports in WebP or AVIF, but Google Ads accepts only JPG/PNG → Convert using https://plomz.com/webp-to-png

  • A product photo is 4000px wide and exceeds file size limits → Compress before upload

  • A square social media image must become 1.91:1 landscape → Resize without cropping important elements

  • A logo sits on a white background and disappears in dark mode → Remove the background and export as transparent PNG

These are daily operational tasks in live campaigns.

File Size Optimization and Load Speed

Smaller files improve:

  • Upload speed
  • Rendering speed in previews
  • Quality consistency across placements

Google recommends staying well below the 5 MB limit. In practice, high-quality ads are usually 150 KB – 500 KB.

You can compress images without visible quality loss using the image compression tools at https://plomz.com/compress-image

Image Content Best Practices (Policy + Performance)

To be approved and perform well:

  • No excessive text overlay
  • No misleading elements
  • Product must occupy at least 80% of the frame for shopping-style creatives
  • Safe margins to prevent auto-cropping

From campaign testing, images with:

  • Clear subject
  • High contrast
  • Minimal text consistently outperform text-heavy banners.

Practical Production Workflow

A reliable production workflow used in active campaigns:

  1. Export master creative at high resolution.
  2. Create square and landscape variants.
  3. Convert to JPG or PNG if needed.
  4. Compress to reduce file size.
  5. Prepare transparent logo versions.
  6. Upload the full asset set.

Common Mistakes That Reduce Ad Strength

  • Uploading only one image format
  • Using low-resolution assets
  • Incorrect logo proportions
  • Heavy text inside images
  • Not providing both square and landscape versions

These issues directly affect delivery and impression share.

Final Thoughts

Google Ads is now an asset-driven system. The advertisers who win are not just better at targeting — they are better at preparing compliant, high-quality, correctly sized visuals.

If your images are properly formatted, lightweight, and available in multiple aspect ratios, your campaigns gain access to more placements, better rendering, and stronger performance signals.
