Image Compressor — Reduce File Size, Keep Visual Quality
Compress large images for faster page loads without sacrificing visual quality. Use the compressor above to process JPG, PNG, WebP, AVIF and HEIC files quickly in your browser.
How compression helps SEO and UX
Page speed is a critical ranking signal and a user expectation. Large images are one of the most common causes of slow pages. Compressing images reduces bandwidth use, accelerates page load, and improves Core Web Vitals metrics like Largest Contentful Paint (LCP). Faster pages keep visitors engaged and increase the likelihood of conversions.
What this compressor does
- Lossy and lossless compression modes for JPEG, PNG, WebP, and AVIF.
- Adjustable quality slider to balance size and fidelity.
- Batch processing to optimize entire folders or product catalogs.
- Preview and compare before downloading compressed files.
Recommended workflow
For best results, resize images to the maximum display size you need (for example, 1200px wide for article images), crop as required, then compress. This sequence preserves important detail while removing unnecessary data. Use lossless compression for graphics with sharp edges and transparency, and lossy compression for photographs to achieve smaller sizes with minimal visual impact.
Tips for different formats
- JPEG: Great for photos. Use progressive JPEGs for perceived speed.
- PNG: Use for graphics and images with transparency; consider converting to WebP for smaller sizes.
- WebP/AVIF: Modern formats that often yield much smaller files; keep fallback JPG/PNG for older browsers when needed.
Accessibility & SEO best practices
- Name files descriptively (e.g., blue-sneakers-sale-800x600.jpg).
- Use generated alt text to improve discoverability and accessibility.
- Serve responsive images with
srcsetand modern formats when supported.
