WebP Compression: Squeeze reduces WebP file weight entirely inside your browser using HTML5 Canvas and mathematical SSIM (Structural Similarity Index Measure) scoring. Files are never uploaded to remote servers or stored in third-party databases. By targeting an SSIM threshold ≥ 0.95, Squeeze removes invisible high-frequency pixel redundancy while retaining razor-sharp edges and color fidelity.
Compression Technical Matrix
| Technical Attribute | Specification |
|---|---|
| Execution Environment | Client-Side (HTML5 Canvas & Web Workers) |
| Privacy Standard | Zero Server Upload (0 bytes transmitted) |
| Target Format | WebP (.webp) |
| Quality Guard Metric | Mathematical SSIM (Perceptual Structural Similarity) |
| Transparency Preservation | Supported (Alpha channel preserved) |
| Batch Export | Multi-threaded queue with instant ZIP archive packaging |
| Cost & Rate Limits | 100% Free ($0) • No caps or subscriptions |
Standard compressors lower quality arbitrarily, resulting in blurry details and blocky artifacts. Squeeze calculates mathematical SSIM scores against your original image, discovering the optimal compression sweet spot where visual differences remain undetectable to the human eye.
Never upload personal photos, receipts, or confidential client artwork to remote servers. All image compression occurs locally in your device's memory via sandboxed Web Workers.
