Production checklist

Audit images before they become page-speed problems

Most image issues are easier to fix before publishing. Check hero images, blog graphics, ecommerce photos and thumbnails before they go live. This prevents oversized files from hurting mobile load time, LCP and perceived speed.

  • Keep large hero images intentional, not accidental.
  • Prefer WebP for web delivery when compatibility is safe.
  • Do not convert photos to PNG unless transparency is required.

Use the audit to decide whether the next step should be compression, WebP conversion or simply keeping the existing file because it is already efficient.

FAQ

Questions about the image audit tool

These answers explain what the audit checks and how to turn the results into practical optimization steps.

Does the image audit tool store my files?

No. The audit runs in the browser and is designed to inspect files locally without storing them.

Why can converting an image make it larger?

Some formats are built for different use cases. PNG can be larger than JPG for photos, while WebP is usually a better delivery target for web pages.

What should I do after finding a large image?

Try compression first if the format is correct. Try WebP conversion if the image is meant for a website and the smaller output keeps acceptable quality.

Can I audit a whole page URL?

This frontend version checks direct image files. Full page crawling is better handled later with backend support, because browsers can block cross-origin page scanning.
