Sparkpix.ai routes detector uploads around its own WebP re-encoder to keep AI labels intact

Sparkpix.ai's detector stores uploads up to 10 MB byte-for-byte because its own WebP re-encoder strips the C2PA and IPTC labels it reads. Chat apps and screenshots lose the same labels, so a missing label clears nothing.

Chrome's canvas.toBlob writes byte-identical PNGs at quality 0.1 and 1.0

Headless Chrome 149 wrote the same 1,345,909-byte PNG via canvas.toBlob at quality 0.1 and at 1.0, one developer's measurements show. A PNG export slider only changes the file if the tool downscales, quantises colours or switches to WebP or AVIF.
