Discovered product capabilities (pending fixture test / edge incubation)
Recorded capability · Not yet scoredThese capabilities have been identified on the product but have not yet undergone fixed-fixture testing. When an emerging capability co-occurs across multiple products, it incubates a new task edge.
Tested task edges (with scores and native artifacts) are strictly separated from discovered untested capabilities (unscored).

- PDF compression：PDF Resizer 75/100 vs TinyWow 93/100
The official tool page states free, unlimited conversion. Numeric size and page limits are not published; the claim is not a guarantee for arbitrary files.
- PDF compression：PDF Resizer 75/100 vs 11zon 75/100
The official pricing page offers a Free tier (2 actions per 6 hours, 128 MB file limit) and an annual AvePDF Premium tier billed once at USD 55/year, with no standalone monthly plan.
- PDF compression：PDF Resizer 75/100 vs avepdf.com 95/100
Confirmed 75 package and 73 monthly subscription capacities; subscriptions start at 1,000 credits. The table says 10 free credits/day while the footer says 10 conversions/day; this conflict does not establish 10 PDFs. PDF-to-Office has a 4-credit base and longer processing incurs more, replacing the historical mixed minutes/count description.
