Compress Images for Website — Faster Loading
Optimize images for web performance. Reduce file sizes for faster loading and better Core Web Vitals scores. Free tool.

Images are typically the largest assets on any web page — accounting for 50–80% of total page weight. Google's Core Web Vitals directly penalize slow-loading images through the Largest Contentful Paint (LCP) metric. Compressing your website images by 60–80% without visible quality loss is one of the easiest wins for SEO and user experience. This tool optimizes images using WebP format (25–50% smaller than JPEG at equivalent quality) or high-efficiency JPEG encoding. All processing runs in your browser — ideal for batch-optimizing hero images, product photos, blog thumbnails, and background images.

Why Compress Images to 200KB
Images are typically the largest assets on any web page — accounting for 50–80% of total page weight. Google's Core Web Vitals directly penalize slow-loading images through the Largest Contentful Paint (LCP) metric. Whether it is web performance optimization or sharing files on messaging apps, keeping your images under 200KB ensures faster delivery and trouble-free uploads. Our browser-based compressor adjusts WebP quality to 80% and optimizes encoding — all without uploading your image to any server.
Best Settings for Web performance optimization
For web performance optimization, WebP at 80% quality gives the best balance of file size and visual clarity. At this quality level, differences from the original are virtually invisible to the naked eye — text remains sharp and colours stay accurate. If the result is still above the target size, try resizing to smaller pixel dimensions first using our Image Resizer.
Complete Privacy — No Server Uploads
Every step of the compression happens in your browser using the Canvas API and modern image codecs — your image is decoded, quality-adjusted, and re-encoded entirely on your device. This makes it safe to compress personal photographs, identity documents, medical records, and confidential certificates. No data leaves your computer, there are no daily usage limits, and you can process as many images as needed.

Frequently Asked Questions
What size should website images be?
Aim for under 200KB per image for general web use. Hero images can be 100–300KB. Thumbnails should be under 50KB. Total page weight from images should ideally stay under 1MB.
Should I use JPEG or WebP for website images?
WebP is recommended — it delivers 25–50% smaller files than JPEG at equal quality. All modern browsers support WebP (97%+ global coverage). Use JPEG as a fallback for legacy support.
Does image compression affect SEO?
Yes, positively. Faster page loads improve Core Web Vitals (LCP), reduce bounce rate, and Google explicitly uses page speed as a ranking signal.
