Refbox
Core Concepts

Assets

Everything about Assets - the files and content you store in Boxes.

Assets are the media, files, Notes, Sketches, and Palettes stored inside a Box. You can view them in the Box, in Gallery View, or open them as Frames on your workspace.

Supported Asset Types

Image

Static images and animated GIF, WebP, and AVIF files for visual reference and annotation.

Video

Motion reference, tutorials, and video clips.

Text Note

Quick notes and text-based information.

Sketch

Lightweight drawing canvases created directly inside Refbox.

Palette

One or more editable colors with saved display and copy formats.

Link

Web URLs for online references.

PDF

Documents, guides, and paginated references.

3D Model

Three-dimensional models for spatial reference.

Audio

Sound effects, music, and voice notes.
Sketch and Palette Assets are created inside Refbox rather than imported from a file format.

Supported File Formats

Standard: png, jpg, jpeg, gif, webp, avif, bmp, svg, tiff, tif, heic, heif

RAW: cr2, nef, arw, dng, rw2, pef, orf, raf, x3f, srw

Adding Assets

Refbox offers multiple ways to add Assets to your Boxes, giving you flexibility based on your workflow.

Add File Button

Use the Toolbar button to browse your computer:

  1. Click the Add File button in the Toolbar
  2. Select one or more files
  3. Click Open to import them into the current Box

If a Section is selected in the Box, imported files from are added to that Section automatically.

Import .txt and .md files to create note Assets from existing text files.

Paste from Clipboard

Perfect for screenshots and copied content:

  1. Copy an image, file, text, or URL to your clipboard
  2. Use one of these methods:
    • Click the Paste from Clipboard button in the Toolbar
    • Focus Refbox and use v . This does not run while a text input has focus.
    • Enable the global Paste From Clipboard shortcut in Settings > Controls to paste while another app has focus.
Clipboard text can be imported as plain text or preserved as formatted/markdown. Configure this in Settings > Behavior > Assets.

When Paste as Palette is on, clipboard text made entirely of supported HEX, RGB(A), or HSL(A) values becomes one Palette instead of a Note. Values can be separated by commas or new lines. Hold Shift while you click the Toolbar's Paste From Clipboard action to force a plain Note for one paste. Configure the default in Settings > Behavior > Colors.

If a Section is selected in the Box, pasted Assets are added to that Section automatically.

Drag and Drop

The quickest method for adding files:

  1. Drag files from your file manager or your browser
  2. Drop them directly onto the Box sidebar or onto a specific Section
  3. Files are instantly imported
    Certain image and video files are converted to more compressed formats upon import. Resolution may also be downscaled for efficiency.

The Behavior > Assets > Drop Location setting controls whether dropped Assets are inserted at the mouse position or added to the bottom of the Box or Section.

Add Notes

Create a text-based Asset:

  1. Click the Add Note button in the Toolbar
  2. Enter your note text
  3. The note is saved to your current Box

If a Section is selected in the Box, the note is saved there.

Add Sketches

Create a blank drawing Asset:

  1. Click the Add Sketch button in the Toolbar
  2. Refbox creates a new Sketch Asset
  3. The Sketch opens immediately in a Frame so you can start drawing

If a Section is selected in the Box, the Sketch is saved there.

Add Palettes

Create a color collection inside Refbox:

  1. Click Add Palette in the Toolbar.
  2. Refbox creates an empty Palette and opens it in a Frame.
  3. Click Add a color, use the screen picker, or paste color values into the Frame.

If a Section is selected, the Palette is saved there. You can also create a filled Palette by pasting one or more color values with Paste From Clipboard.

See Palette Frames for color formats, alpha, editing, copying, and reordering.

Add URLs

To add web references, copy a URL and use the Paste from Clipboard method above.

Refbox will ask whether to save it as a Link or take a Screenshot of the webpage. You can set a default behavior in Settings.

Interacting with Assets In A Box

Refbox provides multiple ways to interact with Assets in the Box sidebar. Most actions support various input methods for mouse, trackpad, and tablet users.

Select Multiple Assets

Bulk selection lets you run one action on several Assets in the current Box.

Start a selection

  • Hover over a large enough Asset and click the circular control in its top-left corner.
  • Or right-click any Asset and choose Select.

The Toolbar is replaced by a bulk-action menu, and the Box stays open while selection is active.

Change the selection

  • Click an Asset to select or deselect only that Asset.
  • Shift-click an Asset to add the range from the last clicked Asset. The range follows saved Box order and can cross expanded Section boundaries.
  • Click Cancel in the bulk-action menu to clear the selection.

If you deselect the last Asset or press the Escape key, bulk selection ends.

You can expand or collapse Sections while selecting. Collapsing a Section keeps its selected Assets in the selection and in the selected count. Shift-click does not add other hidden Assets from a collapsed Section.

Bulk actions

The menu shows the selected count and these available actions in this order:

New Box
Open the Create Box dialog. Choose the icon and name, then create the Box to move the current selection into it. You can change the selection while the dialog is open.
New Section
Open the Create Section dialog and move the current selection into the new Section. You can change the selection while the dialog is open.
Move to Box
Move the selection to another Box without switching to that Box. This action is hidden when there is no other Box.
Move to Section
Move the selection to a Section in the current Box, or to No Section when applicable. This action is hidden when there is no valid destination.
Delete
Move the selected Assets to the Trash after confirmation. Restore them within 30 days from Settings > Data > Trash.
Cancel
Clear the selection without changing any Assets.
Moving Assets to another Box, creating a new Box from them, or deleting them removes their open Frames and Group memberships. Moving Assets between Sections in the same Box keeps them.

While bulk selection is active, Refbox disables Asset previews, Asset and Section reordering, context menus, native file drag, and external file or URL drops. Existing Frames may be hidden during selection but will return when you cancel, unless an action moved or deleted their Assets.

Preview Assets

Click Preview

Click any Asset to open it in a temporary Frame beside the Box. The Asset displays an "eye" icon while being previewed.

As a Frame, you have access to all Frame functionality like zooming, panning, and rotating (depending on the Asset type).

Dismiss the preview:

  • Click the X button on the Frame
  • Press Delete backspace while the Frame is focused

Make it permanent:

Drag the Frame away from the Box. After a certain distance, a pulse animation plays to indicate the Frame is now permanent and the "eye" icon is removed from the Asset.

Zoom Preview

Hold while hovering over an Asset for a quick zoomed preview. Release to dismiss.

Zoom Preview cannot be activated if a Click Preview is already active.

Reorder Assets

Click and drag any Asset within the Box to reorder your collection. Your custom order is preserved automatically.

Sections and Uncategorized

If your Box uses Sections, drag Assets between Sections to move them. Assets outside any Section appear under an Uncategorized divider. The divider is only visible when it contains Assets, or while you are dragging so you can move an Asset out of a Section.

Native File Drop

Export Assets from Refbox to your operating system:

  1. Hold Shift
  2. Drag an Asset from the Box
  3. Drop it into a folder, application, or desktop
Depending on your drop location, you will either create a copy of your Asset, or reference the Refbox Asset directly. Be careful not to overwrite or delete the Asset in the Refbox data folder or you may experience issues.

Creating Frames from Assets

To view an Asset in detail on your workspace, create a Frame:

  1. Click and drag an Asset from the Box sidebar
  2. Drop it onto the workspace area
  3. A Frame opens displaying the Asset

You can create multiple Frames from the same Asset to view it at different zoom levels or transformations.

Learn more about working with Frames in the Frames section.

Asset Context Menu

Right-click any Asset (in the Box or Gallery view) to access context-specific actions. Available options vary depending on the asset type.

Common Actions

Save As
Export a copy of the Asset to a location on your computer. This is not available for Link or Palette Assets.
Move to Box
Move the Asset to a different Box.
Move to Section
Move the Asset to a Section in the current Box, or to No Section. This is available in the Box context menu when there is a valid destination.
Get Info
Open the Asset Info modal to inspect source details and metadata for the selected Asset.
Delete
Move the Asset to the Trash. You can restore it for up to 30 days from Settings > Data > Trash.

Type-Specific Actions

Copy Image
Copy the image to your system clipboard. Animated images are copied as a static image.
Copy Annotated
Copy a version with annotations flattened into the image (shown only when the Asset has annotations).
Copy Text
Copy the note text to your clipboard (text notes only).
Copy Link
Copy the URL to your clipboard (link assets only).
Copy Color / Copy all
Copy one Palette swatch or all swatches in the Palette's saved format. A one-color Palette shows a direct copy action; a multi-color Palette uses a submenu.
Edit Image
Open the Image Editor for annotations, crop, rendering, background, source, and Asset Info (image and animated-image Assets only).
Save Annotated
Export a version with annotations flattened into the image (shown only when the Asset has annotations).
Open Link
Open the URL in your default browser (link assets only).

Asset Info

Use Get Info from an Asset's context menu to inspect where it came from and see type-specific metadata.

Source Details
View the original file path, web URL, or clipboard origin when that information is available.
Metadata
See details such as file size, dimensions, duration, codecs, page count, or 3D model stats depending on the Asset type.

Image Editor

For image and animated-image Assets, right-click and select Edit Image. The Image Editor lets you draw or place text annotations, crop, choose smooth or pixelated rendering, set a transparency background, open the original source, and view Asset Info.

Annotations remain editable and separate from the original file. When you need a flattened result, use Copy Annotated or Save Annotated from an Asset or Frame context menu. The ordinary Copy Image and Save As actions leave annotations out.

See Image Frames for the full annotation, crop, animated-image, copy, and export workflows.

Asset Import Quality

When importing large media files, Refbox offers quality options to balance file size and visual fidelity (currently limited to images only):

Low Quality
Setting
Smaller file size, faster imports, suitable for rough references.
Medium Quality
Setting
Balanced size and quality for most use cases. (Default)
High Quality
Setting
Maximum fidelity, larger file size, best for detailed references.

Configure the default import quality in Settings > Behavior > Assets.

Tips and Best Practices

Use the Temporary Zoom preview to quickly inspect details without opening a Frame.
Set a default URL behavior if you consistently prefer Links or Screenshots when saving URLs.
Use Edit Image to annotate a reference, adjust pixel-art rendering, or set an appropriate background for transparent media.
