Frequently asked questions
- What is a social media safe zone?
- The safe zone is the part of a vertical video that isn't covered by the platform's buttons, captions, and username. Keeping key content inside it ensures nothing important gets hidden.
- Do these tools upload my images?
- No. Previews and resizing happen in your browser, so your images and thumbnails are never sent to a server.
- Are the creator tools free?
- Yes, all of them are free with no watermark and no account required.
