Frequently Asked Questions

How to make an image exactly 300KB?

Our tool automatically adjusts compression level and dimensions to hit the precise 300KB target. For best results, start with high-quality images (1MB+) as they give our algorithm more data to work with while maintaining quality.

Is 300KB a good size for website images?

Yes! 300KB is ideal for most web images - large enough for good quality but small enough for fast loading. Google recommends keeping images under 500KB for optimal page speed.

What's the maximum resolution for a 300KB image?

It depends on content complexity, but typically:

  • JPG: 1200-1800px on the long side
  • PNG: 800-1200px for photos, more for simple graphics
  • WebP: 1500-2000px while maintaining quality

Can I batch compress multiple images to 300KB?

Yes! Upload multiple images and our tool will process them all to approximately 300KB each. Note that very small originals may not reach 300KB even at maximum quality.

Why choose 300KB instead of smaller sizes?

300KB offers the perfect balance - significantly smaller than original files (often 75-90% reduction) while maintaining enough quality for:

  • Website hero images
  • Product photos
  • Blog post featured images
  • Social media sharing
