Adapts your own images only. No artwork is generated or invented — only cropped, scaled, rotated, repositioned, sampled for color, or paired with flat colors and type.

Ctrl+Z to undo, Ctrl+Y or Ctrl+Shift+Z to redo.

1. Images
Front cover image
No front image loaded
Finished flap/back image
No flap image loaded
Spine image optional
No spine image loaded

Upload finished front/flap images, then either use the front cover for the spine or upload a dedicated spine image.

No source images uploaded yet.

2. Assemble

Use the flap upload for a pre-composed back/flap image. For odd album layouts, make the flap externally and upload it here as one image.

3. Edit Panel

Upload artwork or choose a panel to edit.

4. Selected Panel Image

No panel image selected. Click Edit Front, Edit Spine, or Edit Flap.

Fit / Move / Rotate

Advanced crop from source image

Mostly for spine strips. For complicated flap collages, make a finished flap image externally and upload it in section 1.

Crop presets
Rotation presets

Drag the selected image on the canvas to reposition it. Arrow keys nudge 1px; Shift + arrow nudges 10px.

5. Text
Side 1: 0:00 · 0 lines
Side 2: 0:00 · 0 lines

Durations like “Track Name (3:42)” are totaled automatically. Leave generated flap text off when you upload a finished flap image.

6. Backgrounds

A panel override replaces the global background for that panel only.

7. Color Sampling

Useful when only part of a source (e.g. a tracklist crop) is placed — sample the full source's color and apply it to the whole panel so it looks continuous.

8. Guides
9. Project

Autosave keeps a local browser copy when storage allows. JSON export is still the safest backup.
