Compress Image for Website Free - Boost SEO & PageSpeed
Compress Images for Your Website — Faster Pages, Better Rankings
Images are typically the largest files on any web page. Large images slow down load times, hurt Core Web Vitals scores, and cost you search engine rankings. Our free website image compressor reduces your image file sizes by up to 90% without visible quality loss — all processed locally in your browser, nothing uploaded.
How Image Size Affects Your Website
Google measures Largest Contentful Paint (LCP) — the time it takes for the main image on a page to fully load. If your hero image is 2 MB, it takes several seconds to load on a mobile connection. The same image at 200 KB loads in under a second. This directly affects your Google rankings, especially on mobile searches.
Target File Sizes by Use Case
Hero images and banners: Under 300 KB. Blog post images: Under 150 KB each. Product thumbnails: Under 50 KB. Background images: Under 200 KB. For most websites, total page image weight should be under 1 MB for fast mobile load.
Format Recommendations
Use WebP for all web images — it is 25–35% smaller than JPG at the same quality. If you need maximum compatibility, JPG for photos and PNG for graphics with transparency. ImageXpo can convert to WebP from any format.
Private, Free, No Limits
All compression runs in your browser. Nothing is uploaded. No account required.
Frequently Asked Questions
What image file size should I aim for on my website?
Under 200 KB per image for most uses. Hero images can be up to 300 KB. Product thumbnails should be under 50 KB. The smaller the better for load speed, as long as visual quality is acceptable.
Will compressing images affect my Google rankings?
Yes, positively. Faster page load times improve Core Web Vitals scores, which are a Google ranking factor. LCP (Largest Contentful Paint) is directly affected by image file sizes.
Should I use JPG or WebP for my website?
WebP for modern websites. It is 25–35% smaller than JPG at equivalent quality and supported by all browsers since 2020. Keep JPG as a fallback for maximum compatibility with older systems.
