Peer product comparison across shared task edges
Matched by overlapping tested task edges; compare site-wide billing models alongside per-task benchmark scoresThe official pricing page and credit table state that guests get 5 free runs and registered Free accounts receive 10 one-time Nero Credits (Standard/Photo/Anime 2× costs 1 credit/image, 4× costs 2 credits/image, paid-only 8× costs 4 credits/image). Standard monthly is USD 21.95/month promotional (regular USD 24.99/month, 300 credits/month). The yearly promo banner displays only "7.66 USD per month" (3,000 credits/year) without printing the annual invoice total before login, so the annual total is marked unverified.

Optimizilla (imagecompressor.com) shines with its interactive Before/After comparison canvas and 'Colors: 224' fine-tuning slider, shrinking our 4.14 MB anchor by 57.64% to 1.75 MB at PSNR=38.98 dB; however, users must watch out for two green 'DOWNLOAD EXTENSION' fake download ad banners directly above and below the workspace (01_landing.png, 02_workspace.png).
