What is the Image Optimization Lab?

The Image Optimization Lab is a single-image analysis tool that automatically generates multiple compressed versions of your uploaded file — WebP at 90%, 80%, and 60% quality, plus JPEG at 80% — all processed locally in your browser using HTML5 Canvas. No image data ever leaves your device.

Unlike batch conversion tools that process many files at once, the Lab focuses on giving you fine-grained insight: exact byte sizes, percentage savings, visual star ratings, and a live before/after drag slider so you can make an informed decision before downloading.

When should you use the Lab vs. batch tools?

🔬 Optimization Lab

  • Evaluating a hero image for your website
  • Comparing quality trade-offs before committing
  • Learning how different formats affect a specific image
  • Finding the optimal preset for a single critical asset

⚡ Batch Tools

  • Converting dozens of product photos at once
  • Processing a full image directory with one click
  • You already know your target format and quality setting
  • Exporting a ZIP archive of all converted files

Understanding the Quality Ratings

Star ratings in the comparison table reflect the typical visual impact of each preset:

  • ★★★★★ WebP 90% — Near-lossless. Virtually indistinguishable from original. Ideal for print-quality web assets.
  • ★★★★☆ WebP 80% — The sweet spot. Perceptually identical to most viewers while delivering 40%–60% size reduction. Best for general web use.
  • ★★★☆☆ WebP 60% — Aggressive compression. Some softness on high-detail areas. Best for thumbnails and social previews where download speed is critical.
  • ★★★★☆ JPEG 80% — Excellent compatibility fallback. Larger than WebP equivalent but universally supported including legacy browsers and email clients.
