DIY Wallpaper - Photo Collage
Overview
DIY Wallpaper - Photo Collage, developed by iClick Education / SkyIT, is an on-device canvas editor designed for authoring custom wallpapers, photo grids, and digital scrapbooks. Rather than acting simply as an image distribution catalog, the application provides authoring tools that let users transform personal photo collections into customized home and lock screen layouts.
The application's feature set combines an image composition canvas, vector graphic overlays, and automated subject segmentation. Users can import multiple images, arrange them within structured grid templates or freeform scrapbooking layouts, and adjust border spacing, padding, and backdrop textures.
The automated segmentation tool isolates subjects, portraits, or objects from personal photos, allowing them to be placed over curated design templates such as soft pastel gradients, anime aesthetics, or minimalist collage frames. The editor formats compositions to match modern smartphone aspect ratios, preventing the awkward cropping issues that can occur when applying standard camera photos directly through default system galleries. Finished designs can be saved to local storage or applied directly to the device interface using the Android WallpaperManager API.

How does DIY Wallpaper ensure collages match specific device screen dimensions?
The editor queries display metrics from the operating system, providing canvas presets configured to the screen's native resolution and aspect ratio to prevent unintended cropping.
Does the subject cutout tool require manual path selection?
The application uses an automated edge-detection segmentation tool to identify and isolate subjects, while also offering manual brush controls for fine corrections.
Are exported wallpaper designs compressed or downsampled?
Compositions are rendered and exported at high-resolution raster settings matching the target screen dimensions, maintaining visual clarity on high-density displays.
Can the design canvas be used without an active internet connection?
Basic layouts, local image imports, and local sticker packages work offline, but downloading new decorative themes, cloud fonts, and graphic templates requires an active internet connection.
Can completed creations be exported for use outside of wallpaper settings?
Yes. Finished collages can be saved to the local device storage as standard JPEG or PNG files for sharing on social platforms or messaging apps.
