Why Compress Web & Photo Images?
Uncompressed photos and screenshots slow down website load speeds and exceed email attachment limits. Compressing images removes bloat, optimizes color quantization, and speeds up web delivery.
PNG Compression Trade-Offs & Scaling
Because PNG is a lossless format without standard quality sliders, PNG compression at higher tiers applies a subtle dimension scale (95% scale for Recommended, 85% scale for High) to achieve meaningful size savings while maintaining sharp, legible text.
Frequently Asked Questions
Everything you need to know about compressing images locally.
How does in-browser image compression work?
Our tool processes your JPG, PNG, and WebP images directly inside your browser RAM using the HTML5 Canvas API. It re-encodes pixel matrices and strips redundant metadata headers without sending your photos to any remote server.
How does PNG compression handle file size savings?
Because PNG is a lossless format without floating-point quality settings, our Recommended and High compression tiers apply a subtle dimension scale (95% scale for Recommended, 85% for High) alongside metadata stripping. This achieves 40% to 70% file size savings while keeping text and graphics completely crisp.
Will my original image file format be preserved?
Yes! JPG photos output as JPG, WebP images output as WebP, and PNG graphics output as PNG by default. Your original image format is preserved 100% throughout the process.
Are my private photos and graphics secure?
100% secure. Because all processing is calculated locally in your device RAM, zero bytes of your confidential graphics, screenshots, or personal photos ever leave your machine.
Can I compress multiple images simultaneously?
Yes! You can drop single or multiple JPG, PNG, and WebP images at once. Compress them all in parallel and download them individually or as a single combined ZIP file.
