Canva Pro takes it, 8.7/10 against 8.3, on quality, value and range: it covers images, video and PDF where CapCut Pro is images and video, and Bulk Create stamps your own branding across hundreds of designs in a way CapCut has no answer to.
Neither is a watermark remover, and that is the point. Canva Pro licenses the premium asset so the tiles never render; CapCut Pro drops the end-card from every future export. Both fix the mark at source, which beats reconstructing it every time — but only for marks their own app created. Against a logo burned in elsewhere, both are useless.
