Best Image Compression Practices
For website optimization, aim for images under 100KB. Use WebP format for modern browsers as it provides 25-35% better compression than JPEG. For photography portfolios, maintain quality above 80% to preserve detail. E-commerce product images should balance file size with visual clarity - typically 70-85% quality works best.
Our tool works similarly to professional software like Adobe Photoshop's Save for Web feature, but with the convenience of browser-based processing. No need for expensive software subscriptions or complex workflows.
Frequently Asked Questions
How much can I compress an image without losing quality?
For JPEG images, you can typically achieve 60-80% compression while maintaining good visual quality. PNG images can be compressed by 20-50% depending on content. WebP format offers the best compression ratios, often 25-35% smaller than equivalent JPEG files.
What's the difference between lossy and lossless compression?
Lossy compression (JPEG, WebP) reduces file size by removing some image data, which may slightly reduce quality. Lossless compression (PNG) maintains perfect image quality but achieves smaller file size reductions. Our tool supports both methods.
Is this tool better than Photoshop or Lightroom for image compression?
Our tool uses similar compression algorithms to professional software like Adobe Photoshop and Lightroom. While it may not have every advanced feature, it's perfect for web optimization and general use, plus it's completely free and works in your browser.
Can I compress images for social media platforms?
Yes! Our tool is perfect for optimizing images for Instagram, Facebook, Twitter, and other social platforms. Use the resize feature to match platform requirements and compress to reduce upload times while maintaining visual quality.
What image formats are supported?
We support JPEG, PNG, WebP, GIF (first frame), and BMP input formats. You can convert and compress to WebP, JPEG, or PNG output formats. WebP is recommended for web use due to superior compression efficiency.
