Frequently Asked Questions
How much can I compress images without quality loss?
JPEG images can typically be compressed 40-60% with no visible quality loss. PNG files can often be reduced 20-40% through lossless compression. The optimal setting depends on the image content and its intended use.
Which image format should I use for the web?
WebP offers the best compression-to-quality ratio for most web images. Use JPEG for photographs, PNG for images requiring transparency or sharp text, and SVG for icons and logos.
Does compression affect image dimensions?
No, compression reduces file size only - it does not change the width or height of your image. To resize dimensions, use our Image Resizer tool instead.
