Guide
When an image attachment looks wrong, check dimensions, alpha and bytes separately. A smaller pixel count does not guarantee a smaller file, and JPEG cannot preserve transparency.
I maintain CELL FACTORY. This is a reproducible check of our existing browser-local image tool, not a customer result or a claim to outperform other converters.
Synthetic fixture (run this only in your own browser test page):
const c = document.createElement('canvas');
c.width = 640; c.height = 480;
const x = c.getContext('2d');
x.fillStyle = '#c00000';
x.fillRect(160, 120, 320, 240);
// The remaining pixels are transparent.
Save the canvas as PNG. In the converter, request width 320, JPEG output and quality 85.

Checks worth keeping in an acceptance test:
The tool uses local browser canvas processing; there is no image-upload step in this workflow. The site separately offers optional aggregate usage measurement. Browser and encoder versions can change bytes and lossy pixels, so repeat the test on the target device before delivery.

Limitations: still images only in this test; no animation-preservation, photographic-quality or cross-browser speed claim. Custom paid development is separate from using the free tool.
