Image Optimizer — Free, Fast & Private
Image optimization means reducing file size while keeping images looking good. MiniPx does this by combining smart compression with optional dimension reduction — the two most effective techniques for shrinking images.
For websites, optimized images load faster, improve Core Web Vitals scores, and reduce bandwidth costs. A typical unoptimized hero image at 2-5MB can be reduced to 100-300KB with no visible difference on screen.
The Smart preset in MiniPx is designed for this exact use case. It applies moderate compression that preserves visual quality while cutting file size by 60-80%. For more aggressive optimization, the Tiny preset pushes compression further.
MiniPx processes images entirely in your browser. Unlike cloud-based optimizers, your images are never uploaded to any server. This makes it safe for optimizing product photos, client assets, and sensitive documents.
Batch optimization handles multiple images at once — upload an entire folder of product photos and optimize them all with consistent settings. Each file shows its original and optimized size so you can verify the results.
