Image Compressor

The tool accepts JPEG, PNG, and WebP images and targets a user-specified size cap, commonly 40 KB, for fast web delivery. It is intended for web publishers, developers, designers, and marketers who must balance file size with visual quality.

Conceptually, the system analyzes image content using per-format encoding strategies and iteratively compresses while monitoring the resulting size. It applies perceptual optimization to preserve key visual features, adjusts subsampling and quality factors, and may convert to WebP when advantageous. The process continues until the target size is achieved or until further compression would degrade perceptual quality beyond an acceptable threshold.

Core features include multi-format input support, target size constraint, an optional target format, a quality slider, metadata stripping, and a downloadable compressed file. It provides size estimates and savings metrics to help decision making and asset planning.

Use cases cover hero images on PDPs, product galleries, social media previews, newsletter assets, and mobile-delivered graphics. The unique value lies in enforcing a predictable target size while maintaining perceptual quality, together with a simple, file-based workflow that integrates into content pipelines.
