Why Image Compression is Essential for Website Speed & SEO

Updated: October 2, 2025 • 5–6 min read

Did you know that images make up over 60% of a website’s total page weight? Oversized JPGs and PNGs can slow your website dramatically, hurting both user experience and Google rankings. This is where image compression comes in—reducing file sizes without visible quality loss.

Why website speed matters for SEO

• Ranking factor: Google considers page speed a direct ranking signal.
• User experience: Slow sites see higher bounce rates and lower conversions.
• Mobile-first: On 4G/5G networks, compressed images load significantly faster.

How image compression helps

1. Reduces file size by 50–80% without losing quality.
2. Lowers bandwidth usage and hosting costs.
3. Delivers faster page loads → better SEO & engagement.

Best practices for web images

• Use JPG for photos, PNG/WebP for graphics and transparency.
• Keep images under 200KB whenever possible.
