Step-by-Step Optimization

1. Start with High Quality

Always begin with the highest quality source image available.

2. Resize Correctly

Resize to exact platform dimensions to avoid cropping issues.

3. Choose the Right Format

• Photos → JPG
• Graphics → PNG
• Animations → GIF or MP4

4. Optimize File Size

Compress without visible quality loss:

• JPG: 80-85% quality
• PNG: Use PNG-8 when possible

5. Check Color Profile

Use sRGB for consistent colors across devices.

Common Mistakes to Avoid

Low Resolution Images

Uploading images smaller than recommended dimensions results in pixelation when scaled up.

Wrong Aspect Ratio

Images get awkwardly cropped if aspect ratios don't match platform requirements.

Over-Compression

Visible artifacts and blurry text hurt your brand perception.

Ignoring Mobile Preview

Most social media is consumed on mobile - always check how images appear on smaller screens.
