Compress Image for Website

Google's Core Web Vitals score includes Largest Contentful Paint (LCP), which measures how quickly the main image on a page loads. Images over 200KB are one of the most common reasons a page fails LCP. Google PageSpeed Insights directly flags oversized images as an opportunity for improvement.

For every additional second of page load time, conversion rates drop by roughly 7% (Akamai research). Compressing images to under 200KB is one of the highest-ROI performance improvements available — it costs nothing, takes seconds, and directly affects your Google ranking.

Hero images (full-width banners): Aim for 150-300KB. These are the largest images on the page but they need to load fast. Compress to 200KB and use 1920x1080 dimensions.

Product images: 100-200KB. Customers scroll through many products, so each must load instantly. At 200KB and 1000x1000 pixels, product images look sharp and load fast.

Blog and article images: 50-150KB. These are secondary to the text and should load instantly. Most blog images look fine at 800x500 pixels compressed to under 100KB.

Thumbnails and icons: Under 30KB. Small images that appear in lists should be tiny. 400x300 at 50% quality hits this target easily.

1. Resize first: Use our Resize tool to set the correct pixel dimensions for each image's use case (see above). Sending a 4000x3000 camera photo to a 400x300 thumbnail slot wastes bandwidth on pixels no one sees.

2. Compress second: Use this tool to target under 200KB. JPG for photos, PNG for graphics.

3. Convert to WebP (optional but recommended): Use our WebP converter for a further 25-35% size reduction on modern browsers. Serve JPG as a fallback for email and legacy systems.

Following these three steps consistently will push your PageSpeed score from 60-70 into the 90+ range, which Google rewards with better rankings.
