Why Compress Images?
Image file size directly impacts website load speed, Google PageSpeed score, storage costs, email attachment limits, and social media upload times. A typical unoptimized website image is 2–5MB. After compression, the same image can be 200–500KB with no visible quality loss.
Compression Results You Can Expect
JPG photos: 50–75% size reduction at quality level 80. PNG graphics: 40–60% reduction using lossless PNG optimization. WebP: 25–35% smaller than equivalent JPG at the same quality. Typical photo: 3MB → 400KB. PNG icon: 200KB → 60KB.
How to Compress Images — Step by Step
Upload one or multiple images (JPG, PNG, WebP, GIF), adjust the quality slider (85 is recommended for web, 70 for smaller size), preview the compressed result alongside the original, and download compressed files or ZIP.
Compression Modes
Lossy compression (JPG): adjustable quality slider, best size reduction. Lossless PNG optimization: no quality loss, smaller size through metadata removal and palette optimization. WebP conversion: convert JPG/PNG to WebP for additional 25–35% savings.
Image Compression and SEO
Google's Core Web Vitals measure Largest Contentful Paint (LCP) — largely determined by image load speed. Properly compressed images directly improve your LCP score and overall PageSpeed rating, which affects search rankings.
Batch Image Compression
Upload up to 50 images at once. Each is compressed with your chosen settings simultaneously. Download all compressed files in a ZIP archive. Massive time saver for compressing entire photo libraries or product image sets.
Frequently Asked Questions
Quality 85 is the sweet spot for web images — excellent quality at about 50% smaller file size. Use 70–75 for maximum compression where file size is critical. Use 90–95 for print-quality output.
Our tool compresses a copy of your image. Your original file is unchanged. We recommend keeping original files and using compressed versions for web/sharing.
Yes. PNG lossless optimization reduces file size by removing metadata, unused colors, and optimizing the compression algorithm without changing a single pixel.
Typically 50–75% reduction. A 3MB JPG becomes 600KB–1.5MB depending on the quality setting. Results vary by image content — photos with lots of detail compress less than simple images.
Yes. GIF compression reduces color palette and frame data to shrink animated GIF file sizes.
