How to Optimize Images for Compose.page Without Losing Quality

High-quality images improve perception, but heavy images kill performance. This guide walks through an efficient image optimization workflow tailored for Compose.page so your pages look crisp and load quickly.

Understand formats and when to use them

• WebP: Best balance of quality and file size for modern browsers.
• JPEG: Good for photos where WebP isn't available; use progressive encoding.
• PNG: Best for images with transparency or simple graphics, but large for photos.
• SVG: Ideal for logos, icons, and illustrations — scalable without cost.

Step-by-step optimization workflow

1. Choose the right format: Convert photos to WebP with fallback JPEGs if needed.
2. Resize to display size: Don't upload a 4000px image if your hero displays at 1200px.
3. Compress: Use tools like Squoosh, ImageOptim, or command-line cwebp for automated pipelines.
4. Use srcset: Provide multiple resolutions so browsers pick the best fit for device DPR.
5. Lazy-load offscreen images: Compose.page supports lazy-loading; prioritize LCP images above the fold.

Automation and asset pipelines

For teams, automate image optimization in CI. A simple pipeline: upload raw assets, run a build step to generate resized WebP/JPEG versions, and output optimized filenames. Compose.page can then reference those generated assets for best performance.

Balance quality vs. size

Experiment with quality settings: web-quality 70–80 for photos often looks great while cutting file size dramatically. For illustrations and logos, keep vector SVGs or use lossless PNGs for tiny files.

“Optimized images are a speed and conversion win — they improve perceptions and reduce bounce.”

Accessibility and SEO considerations

• Always add descriptive alt text for images.
• Use meaningful file names (e.g., product-name-hero.webp) for improved discoverability.
• Define image dimensions to avoid layout shifts and improve Core Web Vitals.

Tools we recommend

• Squoosh — visual compression for designers.
• ImageOptim — batch resizing and compression on macOS.
• cwebp & libvips — CLI tools for CI automation.
• Cloud image services — imgix, Cloudinary for on-the-fly resizing and format delivery.

Quick checklist before publishing

• Hero and LCP image optimized and under 200 KB when possible.
• Responsive srcset in place.
• Alt text added to all images.
• Lazy-load non-critical images.
• Test Lighthouse and Core Web Vitals.

Optimizing images does add a step to publishing, but it's one of the highest ROI optimizations for user experience and SEO. With Compose.page's flexible asset management and a small CI pipeline, you can consistently ship fast, beautiful pages.
