Last updated March 22, 2026

How to Use

1. Click the upload area or drag and drop an image

4. Preview the compressed image to verify quality
5. Click "Download Compressed" to save the optimized image

Tips for Best Results

• Start with the highest quality source image available — compression from a compressed image degrades quality faster
• Resize images to their display dimensions before compressing — a 4000px image displayed at 800px wastes bandwidth
• Use WebP for new projects — it offers 25–35% better compression than JPEG at equivalent quality
• Strip EXIF metadata for web images — removes GPS coordinates, camera info, and reduces file size
• Use lossless PNG compression for logos and icons — lossy compression creates visible artifacts on sharp edges
• Enable lazy loading for below-fold images — reduces initial page load time regardless of compression

All compression happens in your browser using WebAssembly. Your images are never uploaded to any server.

Why Compress Images?

Large images slow down websites, increase bandwidth costs, and hurt SEO rankings. Compressed images load faster, improve user experience, and reduce hosting costs. Google considers page speed a ranking factor, making image optimization crucial for SEO.

• Faster Page Load: Compressed images load 50-80% faster, improving user experience
• Better SEO: Page speed is a Google ranking factor - faster sites rank higher
• Reduced Bandwidth: Save hosting costs and mobile data for users
• Improved Mobile Experience: Critical for users on slow connections
• Storage Savings: Reduce server storage requirements

Compression Examples

JPEG Photo Compression:
  Original:   hero-image.jpg    — 2.4 MB (4000×2667px)

  Quality 60: hero-image.jpg    — 180 KB  (93% reduction) ← aggressive
  Quality 40: hero-image.jpg    — 95 KB   (96% reduction) ← noticeable quality loss

PNG Graphic Compression:
  Original:   logo.png          — 145 KB  (800×600px, transparent)
  Compressed: logo.png          — 62 KB   (57% reduction, lossless)
  WebP:       logo.webp         — 38 KB   (74% reduction, near-lossless)

WebP Conversion:
  Original:   product-photo.jpg — 890 KB
  WebP Q80:   product-photo.webp — 210 KB (76% reduction)
  WebP Q60:   product-photo.webp — 95 KB  (89% reduction)

Quality 90–100 (minimal compression):
  Use for: Print-quality images, portfolio photography, product hero shots
  Result: Nearly identical to original, small size reduction
  File size: ~60–80% of original

Quality 70–85 (recommended for web):
  Use for: Blog images, product photos, background images
  Result: Visually identical to most viewers
  File size: ~20–40% of original

Quality 50–65 (aggressive compression):
  Use for: Thumbnails, preview images, social media previews
  Result: Slight quality loss visible on close inspection
  File size: ~10–20% of original

Quality below 50 (maximum compression):
  Use for: Tiny thumbnails, placeholder images
  Result: Visible compression artifacts
  File size: ~5–10% of original

Choose JPEG when:
  ✅ Compressing photographs
  ✅ Maximum browser compatibility needed
  ✅ No transparency required
  ✅ File size is the priority

Choose PNG when:
  ✅ Image has transparency (logos, icons, UI elements)
  ✅ Image has text or sharp edges (screenshots, diagrams)
  ✅ Lossless quality is required
  ✅ Image will be edited further

Choose WebP when:
  ✅ Targeting modern browsers (Chrome, Firefox, Safari 14+, Edge)
  ✅ Best compression ratio needed
  ✅ Both photos and graphics in one format
  ✅ Building a new website (not supporting IE)

Choose SVG when:
  ✅ Image is a logo, icon, or illustration
  ✅ Image needs to scale to any size
  ✅ File size must be minimal
