What this page counts
The inventory has 31 matching rows for this operation. 11 products have confirmed evidence and 14 have partly confirmed evidence; unresolved rows are excluded. A product appears only when the inventory names this exact operation. A vendor that bundles several conversions into one unspecified tool is not counted here.
The tiers describe commercial access at the record level. A free choice may still have usage limits, and an offline choice may require a paid licence. Check the linked product record before relying on a feature. The inventory was last checked 2026-10-23; the source and date for each product are on its record.
