Image Converter - Convert Images Online Free

Last updated March 22, 2026

Format Comparison Quick Reference

• JPEG — best for photos, no transparency, lossy, universal support
• PNG — best for graphics/logos, supports transparency, lossless, larger files
• WebP — best overall for web, supports transparency + animation, 25–35% smaller than JPEG/PNG, modern browsers only
• GIF — only for simple animations, limited to 256 colors, largely replaced by WebP/video
• BMP — uncompressed, very large files, avoid for web use
• SVG — vector format, infinitely scalable, best for logos and icons, not for photos

All conversions happen in your browser using the Canvas API. Your images are never uploaded to any server.

Common conversions and their use cases:

PNG → JPEG:
  When: Sharing photos that don't need transparency
  Result: Smaller file size (lossy compression)
  Example: screenshot.png (2.1 MB) → screenshot.jpg (180 KB, quality 85)

JPEG → PNG:
  When: Need to add transparency or edit without quality loss
  Result: Larger file, lossless quality
  Example: photo.jpg (450 KB) → photo.png (1.8 MB)

Any format → WebP:
  When: Optimizing for modern web browsers
  Result: 25–35% smaller than JPEG/PNG at equivalent quality
  Example: banner.jpg (890 KB) → banner.webp (210 KB)

PNG → SVG:
  When: Converting simple logos/icons to scalable format
  Note: Requires vector tracing — best for simple graphics

GIF → WebP:
  When: Replacing animated GIFs with smaller animated WebP
  Result: Up to 64% smaller than GIF
  Example: animation.gif (4.2 MB) → animation.webp (1.1 MB)

Converting PNG to JPEG with different quality levels:

Source: product-photo.png (transparent background, 1200×900px)

Step 1: Choose background color for transparency
  → White (#FFFFFF) for product on white background
  → Custom color to match your page background

Step 2: Select quality:
  Quality 95: product.jpg — 380 KB  (near-lossless, for print/archive)
  Quality 85: product.jpg — 165 KB  (recommended for web product photos)
  Quality 75: product.jpg — 95 KB   (good for thumbnails)
  Quality 60: product.jpg — 55 KB   (aggressive, visible artifacts on close inspection)

Step 3: Download and verify
  → Check for compression artifacts around text and sharp edges
  → Adjust quality if needed

Converting existing image library to WebP:

Before:
  hero.jpg        — 1.2 MB
  about-team.jpg  — 890 KB
  logo.png        — 145 KB
  icon-set.png    — 78 KB

After WebP conversion:
  hero.webp       — 285 KB  (76% smaller)
  about-team.webp — 198 KB  (78% smaller)
  logo.webp       — 42 KB   (71% smaller)
  icon-set.webp   — 22 KB   (72% smaller)

HTML with WebP + fallback for older browsers:
<picture>
  <source srcset="hero.webp" type="image/webp">
  <img src="hero.jpg" alt="Hero image">
</picture>
