Independent compression check

Test a specific page in PageSpeed Insights and inspect the files

The automatic audit counts unique images for which PSI identifies savings from better encoding or compression. Reusing one URL does not multiply the price.

A page is analysed for image opportunities before comparing original and compressed files with the same format and dimensions
PSI provides an estimate; comparing the actual files confirms available savings.

PageSpeed Insights check

  1. Open PageSpeed Insights.
  2. Enter the exact page URL rather than only the domain.
  3. Run the mobile test and open Performance.
  4. Find the insight about efficient encoding or improved image delivery.
  5. Save the listed file URLs and estimated savings.

Evidence and limitations

Save the page URL, PSI link or screenshot, unique-file list and estimated savings. A specialist still checks originals before batch replacement because some may already be close to optimal compression.

The base price covers up to 1,000 images. Above that amount, the formula increases the total while reducing the per-file cost.
