How does the client-side JavaScript background removal work?
The background removal tool inspects pixel colors along the boundary of the selected image. It performs a flood-fill algorithm that measures the Euclidean delta-E color distance between adjacent pixels and the detected background hue, replacing matched pixels with transparent alpha while softening edges with an anti-aliasing feathering step.

How do I save and restore my collage state using JSON?
Click the "Save JSON" button in the navigation header to export a serialized JSON document containing your canvas size, background settings, image layers, positions, scale, angles, and transparent cutouts. Use the "Load JSON" button anytime to re-hydrate the full workspace with all layers intact.

Are my uploaded photos sent to any server?
No. All photo ingestion, scaling, layout randomization, and background removal algorithms execute strictly client-side within your browser window using standard web technologies. Your private photos never leave your personal computer or mobile device.

Can I adjust layer order, bring items to front, or send backward?
Yes. The Layer Stack panel and Item Properties toolbar offer Up and Down layer reordering controls. You can also click directly on items in the visual layer list to focus any element, or use keyboard shortcuts to reorder elements and build complex dimensional collages.

How do I export my collage as a high-resolution image?
Click the "Export High-Res" button in the upper right. The application renders all collage elements at crisp full canvas resolution onto an off-screen buffer, captures all shadow and polaroid treatments, and generates a downloadable high-density PNG file.
help
Can I drag and drop images directly onto the canvas?
Yes. The entire canvas and upload dropzone accept drag-and-drop actions for standard image formats including PNG, JPEG, WEBP, and GIF. Multiple files can be dropped simultaneously to quickly populate your project.

How does the Magic Wand eyedropper mode function?
When you select the Wand Pick tool in the Background Removal Studio, tapping any point on the preview sampling canvas targets that specific color. It then isolates and erases matching continuous areas based on your chosen Color Tolerance and Feathering sliders.

What canvas aspect ratios are supported?
Image Collage Studio comes loaded with pre-configured aspect ratios including 1:1 Square (1080x1080), 4:3 Classic Art (1200x900), 16:9 Landscape Banner (1280x720), and 9:16 Story/Reel format (720x1280) with automatic layout fitting.

Can I use custom color presets or transparent backgrounds?
Yes. You can select solid colors using an RGB color picker, choose gradient backdrops like Sunset, Cyberpunk, or Deep Ocean, or select a transparent canvas back so exported collages can be used directly as stickers or composite overlays.
