Every tool here can be used without paying. Tools marked “Fully free” have no paid plan; tools with a free plan let you start for free and pay only for more usage or features.
“Fully free” means every feature is free. “Free plan” means there is a free tier with limits and a paid upgrade; the card shows the cheapest monthly upgrade when the tool publishes one.
Common limits are a daily or monthly usage quota, lower output quality or resolution, watermarks, and fewer advanced features. Check each tool’s pricing page for the exact terms.
