Fixes App Store Connect ITMS-90717

Remove PNG alpha channel
for App Store Connect.

Fix App Store Connect ITMS-90717 transparency rejections locally. Inspect PNG alpha channels and export true 24-bit RGB opaque PNGs in your browser.

Why App Store Connect rejects opaque-looking PNGs.

Design tools like Figma, Sketch and macOS screenshots often export 32-bit RGBA PNGs (PNG header colorType = 6) even when every pixel has 100% opacity. Apple’s Media Manager inspects the PNG header itself and rejects any file containing an alpha channel. This tool re-encodes each image in your browser as a true 24-bit RGB PNG (colorType = 2) with zero upload.
