Why compression matters
Oversized hero images are a common reason for slow Largest Contentful Paint. Compressing and resizing before upload to your CMS keeps pages snappy and saves bandwidth.
A simple checklist
- Resize to the largest display width you actually need
- Use WebP (or AVIF) for photos when your stack supports it
- Keep JPG quality around 70–85% for most photos
- Prefer PNG/WebP for logos and UI with sharp edges or alpha
- Avoid recompressing the same lossy file many times
Do it privately
PixNest's compressor and resizer use canvas / createImageBitmap in your browser. Nothing is sent to a server — ideal for product shots, screenshots, and personal photos.
