Saving & Projects

Your work is saved automatically in your browser. For portable backups and cross-device transfer, use .gwall files.

• Auto-SaveChanges are persisted to your browser's local storage automatically. Your layout, frames, photos, and analysis data survive browser restarts — but not clearing browser data.
• Import / Export Project (.gwall)Export Project saves a portable .gwall file containing your entire project: every wall, frame inventory, photos, and analysis data. Import Project opens it on any device or browser. The current version opens .gwall files from any older version, but files exported by the current version may not open in older versions of the app.
• Export All ProjectsProBack up everything in one step — every project is saved as its own .gwall file. On desktop, open the Project menu → Export All Projects; on mobile, tap your project's name at the top of the screen, then Export All Projects.
• Import ProjectsProRestore a full backup or move to a new device: import several .gwall files at once and each one becomes its own project. On desktop, open the Project menu → Import Projects; on mobile, tap your project's name, then Import Projects.
• Backup RemindersYour projects live on this device — never on our servers. So GalleryPlanner reminds you from time to time to save a backup, and you can export right from the reminder: Export Project, or Back Up Projects with Pro to export everything at once.
• Undo & RedoUp to 50 levels of undo/redo per project. Use Ctrl+Z to undo and Ctrl+Shift+Z to redo. History is kept for the duration of your browser session.
• Multi-Project EditingProGalleryPlanner Pro unlocks full editing across multiple projects, so you can keep separate spaces — or competing ideas — going at once. Planning several walls in one space? That's Multi-Wall Projects, below.
• Multi-Wall ProjectsProKeep a whole room in one plan: every wall in a project shares one photo library, undo covers them all, and exports include every wall — the Hanging Guide gets a section per wall. Your first wall is always free; adding a second wall and beyond requires Pro.
• Duplicate ProjectProWant to try a different direction without losing what you have? Duplicate makes a complete copy of your current project. On desktop, open the Project menu → Duplicate Project; on mobile, tap your project's name at the top of the screen, then Duplicate.
