How It Works

Compressing an image to 150KB gives you the best of both worlds: a lightweight file that loads instantly, and excellent high-definition visual clarity. Unlike extreme compression, a 150KB allowance means you don't have to sacrifice much resolution. By default, our tool keeps the maximum width at a generous 1200 pixels and maintains a high-quality setting of 75%. This is the perfect sweet spot for modern retina displays and high-res scanned documents. As always, your files are processed securely right in your web browser, ensuring lightning-fast performance and total privacy without any server uploads.

What You Get

Optimized images that balance quality and file size for faster uploads — with exact target sizes, AVIF/WebP/MozJPEG codecs, and unlimited batch ZIP export.

Frequently Asked Questions

Everything you need to know about compressing images online.

Not at all! 150KB provides plenty of data to keep images looking sharp and professional. Unless you are printing massive posters, the compression will be practically invisible to the human eye.
It depends on your original file. Modern smartphones take 4K photos that are 4000+ pixels wide. Our tool automatically scales these down to 1200px (standard HD width for web) which easily brings the file size down to 150KB while keeping it crisp.
Yes, it is highly recommended! Keeping your blog post and product images under 150KB is an SEO best practice. It ensures your website loads incredibly fast, which improves user experience and Google search rankings.
100% safe. All image processing happens locally on your computer or phone. We do not store, view, or upload your photos to external servers.
