Project overview
A connected product, built around the real workflow
Users often need several separate applications to remove a background, resize an identity photo, scan documents, compress images or rearrange PDF pages. Moving files between tools adds friction and increases privacy concerns, especially when a simple edit unexpectedly uploads a personal image to a server.
The application also needed consistent editing and export behaviour across Android, iOS and web while acknowledging platform-specific limitations honestly.
Solution strategy
We built a React Native and Expo application with a shared workspace for AI cut-outs, replacement backgrounds, text, stickers, adjustments, preview and export. The default segmentation engine runs on-device through an off-screen WebView and cached ONNX model, allowing photos to remain on the device; an optional remote provider can be configured by the user.
The broader toolkit includes document scanning, image-to-PDF, PDF-to-image, merge, split and reorder workflows, photo compression and multi-image resizing with document presets. Zustand manages persisted settings and projects, while platform-specific services provide safe web fallbacks for galleries, sharing, ads and segmentation.

Key journey
How the workflow moves
- 1
User selects an image or document
- 2
DocuKit opens the relevant focused tool
- 3
Processing and adjustments are previewed
- 4
The result is exported or shared using supported platform options
Technical architecture
Clear boundaries between each layer
Application layer
Expo and React Native experience with platform-specific capability handling
AI layer
Cached ONNX background-removal model running inside an off-screen WebView
Optional service
remove.bg can be selected when a remote processing engine is preferred
Device layer
Local projects, preferences and native export or sharing capabilities
Engineering decisions
Details that protect the experience
On-device first
The primary background-removal path keeps processing close to the user and caches the model for reuse.
Progressive capability
Native and web builds use explicit fallbacks instead of pretending every device supports identical output.
Focused tool journeys
Each utility has a short select, configure, preview and export flow rather than a crowded all-in-one editor.
Delivered scope
What was brought together
- Mobile application
- Document tools
- Image editor
- On-device AI
Quality and safeguards
Operational details that matter
- MP4 export is not presented as a completed capability
- Some social sharing options depend on operating-system support
- WEBP export and some image adjustments have platform-version limitations
The result
A purpose-built digital product—not a disconnected set of screens
DocuKit brings common image and document tasks into one mobile-first product and keeps the main background-removal path local to the device. The implementation includes explicit fallbacks and disclosures for web, older operating systems, media export and provider-dependent features rather than hiding unsupported behaviour.
No download, retention or monetisation figures are claimed because verified production analytics were not supplied.
