# Apply a new theme, or reset your customizations

Go to **Online Store → Themes**, click **Apply** on a theme and choose **Import demo & apply** or **Start clean**. To reset a theme you customised under *My themes*, use **Sync theme**, which erases all your customisations and restores the original.

## Steps

1. Open **Online Store → Themes** and browse the pre-made themes; use the preview to look at one before applying.
2. Click **Apply**. In the **Import demo data?** dialog choose **Import demo & apply** (adds the theme's sample products, reviews and categories) or **Start clean** (keeps your existing content only).
3. The active theme card now shows **Customize**, which opens the store editor (same as **Online Store → Theme Settings**). Edit, then click **Save**.
4. To build your own theme, click **Create my own theme**, give it a name and description, then open it from *My themes* with **Customize theme** (the editor shows a **Theme Mode** badge). From the same card you can **Edit information** (name, description, cover image up to 5 MB), duplicate, **Delete** or **Share Theme** with another store by subdomain.
5. To reset a customised theme: on its card click **Sync theme** and confirm; "This action will erase all your customizations and restore the original version of this theme."
6. Changes made in the editor are stored with **Save**; page visibility is controlled by the **Published / Unpublished** toggle.

## Common problems

- Sample products appeared after applying → you chose **Import demo & apply**. Remove them from **Products → Manage Products**, **Collections** and **Reviews**.
- I want a fresh copy but keep my work → duplicate the theme in *My themes* before you **Sync theme**.
- I can't find the Customize button → only the active theme shows **Customize**; themes in *My themes* use **Customize theme**.
- I want to upload a theme made outside Dropify → not supported; pick a built-in theme or generate one with AI.
- I received a theme from another store → accept it under **Online Store → Theme Invitations**.
