Image Compress

About Image Compression

Image compression reduces file size while preserving as much visual quality as possible. According to HTTP Archive 2024 data, images account for approximately 45% of the average web page's total weight — making image optimization the single most impactful step for improving page load speed. Effective compression typically reduces JPG file sizes by 60–80% and PNG files by 30–50%, with no perceptible loss of quality at standard quality settings.

This tool uses the browser's built-in HTML5 Canvas API to compress images. All processing happens on your device — your files never leave the browser, ensuring complete privacy.

Key Features

• Five formats supported: JPG, PNG, WebP, GIF, and BMP
• Quality slider: Adjust compression from 10% (maximum compression) to 100% (lossless). The default of 80% is imperceptible to the human eye in most cases
• PNG transparency preserved: PNG compression retains transparent backgrounds — essential for logos and design assets
• Live compression stats: Original size, compressed size, and percentage saved are shown immediately after compression
• Privacy-first: No uploads, no server — files stay on your device

Common Use Cases

Web developers use image compression before publishing assets to improve Core Web Vitals scores and Google search rankings. Social media creators compress images to meet platform upload limits (Instagram: 8MB, Twitter: 5MB) while maintaining quality. Photographers and designers compress preview files before client delivery. Email users compress attachments to stay within inbox size limits. E-commerce teams optimize product photos to speed up their stores.

How to Use

1. Drag and drop your image onto the upload area, or click to select a file (up to 20MB)
2. Adjust the quality slider (75–85 is recommended for the best balance of size and quality)
3. Review the compression results showing original size, compressed size, and savings
4. Click "Download" to save the compressed image
