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.

- Fixture findings
Local processing reduced this fixture by about 56% with adjustable quantisation; useful if you want parameter control.
- Original historical observation
RedKetchup is one of the few tools that lets users manually pick 8-bit quantization dithering algorithms (Atkinson) and inspect pixels side-by-side in a full-screen viewer: it shrinks our 4.14 MB anchor PNG by 56.31% to 1.77 MB locally at PSNR=39.35 dB and SSIM=0.9984 (02_workspace.png, 03_download.png).
- Suitable uses · historical assessment
Developers and UI designers who want fine-grained control over PNG color depth (8/24/32-bit) and dithering algorithms with 100% local browser privacy
