The Fundamental Difference
DeckEdit is a free, browser-only slide editor built for one job: turning finished decks, exported PDFs, and slide images back into fully editable slides. Everything runs on your device. No account, no upload, no subscription. Canva is a broad cloud design suite covering social graphics, documents, and presentations, edited in their web app after you sign in.
Choose DeckEdit when you already have a deck, PDF, or image and need to edit the text and layout without re-uploading to the cloud. Choose Canva when you want a large template and asset library across many design formats and a cloud account is acceptable.
