Image Compressor

About PIXORA Image Compressor

PIXORA compresses images entirely within your browser using the HTML5 Canvas API. Your images are never uploaded to any server, ensuring complete privacy. This tool supports JPEG, PNG, and WebP formats and allows batch compression of multiple images simultaneously.

How Image Compression Works

PIXORA uses lossy compression via the browser's Canvas toDataURL method. The quality parameter (0–100%) controls how much information is discarded during compression. At 75% quality, most images see a significant file size reduction with minimal visible quality loss — the sweet spot for web use.

When to Compress Images

• Website performance – Large images slow page load time; compressed images improve Core Web Vitals scores
• Email attachments – Reduce attachment size for faster delivery and compatibility
• Social media – Faster uploads and within platform size limits
• Storage optimization – Save disk space on phones and computers

Image Format Guide

• JPEG – Best for photographs; supports lossy compression; smallest file size
• PNG – Best for screenshots, graphics with text; supports transparency; lossless but larger
• WebP – Modern format by Google; 25–35% smaller than JPEG at same quality; excellent for web
