Reviewing creative work often means gathering input from several people and keeping track of changes before approval. Online proofing software offers different ways to manage that process. Compare approval workflows, guest reviewers, and version history; video proofing is a relevant distinction when feedback concerns moving images. Custom branding and storage limits also help you assess how an option accommodates review work. Ziflow, Frame.io, and Krock.io are among the products to consider. Check free-plan availability and paid-from pricing, and weigh the listed details against who needs to review each version and how your team moves feedback toward a decision.
27 online proofing software ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
