- Downscale large images to your target display width.
Image compressor: faster pages, lower bandwidth bills
Heavy images are the top cause of slow LCP on marketing sites. Compressing intelligently reduces bytes while preserving acceptable visual quality for the intended viewport size.
Prefer responsive `srcset` in production, not one giant image for all devices.
Practical tips
- Pick quality by inspecting text edges and gradients separately.
- Strip metadata when not legally required to shrink further.
- Try modern formats after checking CDN support.
- Do not recompress JPEGs repeatedly—generational loss adds up.
Common questions
- Lossless vs lossy?
- Lossless preserves pixels but saves less; lossy targets perceptual quality.
- Transparency?
- PNG and WebP handle alpha; JPEG does not.
- Print workflows?
- Use high-quality sources; web compression is not for fine art printing.
