   - **Documents & E-books**: DOCX, HWPX, EPUB, KEPUB, FB2, HTMLZ, TXTZ, MD, TXT, and HTML are translated in place, preserving document structure, headings, bold/italic runs, tables, lists, images, and notes.
   - **Kindle e-books**: MOBI, AZW, AZW3, and PRC formats are translated via EPUB, and can then be routed to any supported target format.
   - **PDF target**: When a document is translated with PDF as the target format, the route planner translates the document model first and then routes the translated document through Filee's standard document-to-PDF export pipeline.

+## Image Quality Models (Offline AI Upscaler)
+
+Filee upscales and restores images locally using an offline AI super-resolution engine based on Vulkan/NCNN (`upscayl-bin` / `upscayl-ncnn`) and curated open-source neural network models (`upscayl/custom-models`). All processing runs 100% offline on your computer; no image data is ever uploaded or sent to external servers.
+
+- **Offline privacy & local execution**: Like all Filee features, image upscaling processes every pixel locally on your machine via direct Vulkan GPU acceleration or CPU mode. No network connection is used during upscaling.
+- **Models catalog**: Curated selection of high-quality image models for photos, digital art, illustration, and restoration:
+  - Compact & fast models (optimized for CPU and integrated GPUs): `4xLSDIRCompactC3`, `RealESRGAN_General_x4_v3`, `RealESRGAN_General_WDN_x4_v3`.
+  - Detailed & high-fidelity models (recommended for dedicated GPUs): `4x_NMKD-Siax_200k`, `4x_NMKD-Superscale-SP_178000_G`, `4xLSDIR`, `4xLSDIRplusC`, `4xNomos8kSC`, `4xHFA2k`, `uniscale_restore`.
+- **Where it lives**:
+  - **Donut Menu**: When an image is dropped or opened in the donut wheel, the **Upscale** preset opens the interactive Upscale dialog to select models, scale factors (1x to 4x), preview output resolution, and upscale directly.
+  - **Settings → Presets**: The "Upscale Image" tool preset can be configured with preferred default models and scale factors.
+  - **Settings → Engines**: "Image Quality Models" engine card with a dedicated **Download Models** manager to browse, search, download, and delete local model files.
+- **Supported formats**: PNG, JPG, JPEG, WEBP, ICO, HEIC, AVIF, BMP, and TIFF.

Subject: [PATCH 2/5] Address review feedback on offline AI upscaler engine and
 UI

- Restore case 'model' to bin extraction in EngineInstaller to prevent Whisper regression
- Add unit test verifying kind 'model' component installation
- Add vcruntime to upscayl-bin on Windows and ensure VCOMP140.DLL is copied next to binary
- Add Upscale flag to ConversionEdge, RoutePlanner, and route jobs via JobQueue
- Use FormatRegistry.Detect and UpscaleTool.TargetFor to avoid raw extensions as format IDs
- Remove 'jpeg' from upscaler supported format IDs
- Safely handle model deletion with try/catch and error dialog
- Add Material trash icon StreamGeometry and fix delete button visibility for installed models
- Cancel token and dispose view model on window closing
- Use ImageEncoder to respect preset quality and icon constraints
- Show live progress percentage during model download in dialog
- Use dynamic theme brushes in UpscaleWindow instead of hardcoded hex values
- Update NMKD notices author to nmkd and clean up docs/ENGINES.md
- Remove 17 leftover keys across all 19 language files

 - **Offline privacy & local execution**: Like all Filee features, image upscaling processes every pixel locally on your machine via direct Vulkan GPU acceleration or CPU mode. No network connection is used during upscaling.
 - **Models catalog**: Curated selection of high-quality image models for photos, digital art, illustration, and restoration:
   - Compact & fast models (optimized for CPU and integrated GPUs): `4xLSDIRCompactC3`, `RealESRGAN_General_x4_v3`, `RealESRGAN_General_WDN_x4_v3`.
-  - Detailed & high-fidelity models (recommended for dedicated GPUs): `4x_NMKD-Siax_200k`, `4x_NMKD-Superscale-SP_178000_G`, `4xLSDIR`, `4xLSDIRplusC`, `4xNomos8kSC`, `4xHFA2k`, `uniscale_restore`.

Subject: [PATCH 4/5] Address second review feedback on offline AI upscaler

- Add vcomp14 conda package to upscayl-bin Windows components and copy OpenMP runtime in CopyRuntime
- Auto-orient frames before upscaling and preserve EXIF and ICC profiles on results
- Fall back unsupported writable target formats to PNG in UpscaleTool.TargetFor
- Connect UpscalerConverter edges from all readable image sources to supported target formats
- Close upscale dialog immediately upon job start and delegate progress/completion to conversion toast
- Retain shared package components (like vcruntime) during package uninstallation in EngineInstaller
- Check AppLocalRuntime for missing DLLs and refuse cleanly when Vulkan GPU is absent
- Replace fixed timeout with stall/inactivity timeout and use unique temp file names
- Set PresetEditorView scale slider minimum to 2 and use home.files localization key in UpscaleViewModel
- Remove unused GpuId property, remove unused upscale.processing key, and update schema 69 comments
- Clarify offline Vulkan requirement in docs/ENGINES.md and remove inaccurate CPU claims
- Add unit tests for shared component uninstallation, auto-orient, profile preservation, and format fallback
- Revert out-of-scope edits in ClipWindowTests, AppHost, EnginesPageViewModel, and EnginesPage

 Filee upscales and restores images locally using an offline AI super-resolution engine based on Vulkan/NCNN (`upscayl-bin` / `upscayl-ncnn`) and curated open-source neural network models (`upscayl/custom-models`). All processing runs 100% offline on your computer; no image data is ever uploaded or sent to external servers.
 
-- **Offline privacy & local execution**: Like all Filee features, image upscaling processes every pixel locally on your machine via direct Vulkan GPU acceleration or CPU mode. No network connection is used during upscaling.
+- **Offline privacy & local execution**: Like all Filee features, image upscaling processes every pixel locally on your machine via direct Vulkan GPU acceleration. No network connection is used during upscaling. Requires a Vulkan-compatible graphics device.
 - **Models catalog**: Curated selection of high-quality image models for photos, digital art, illustration, and restoration:
-  - Compact & fast models (optimized for CPU and integrated GPUs): `4xLSDIRCompactC3`, `RealESRGAN_General_x4_v3`, `RealESRGAN_General_WDN_x4_v3`.

+  - **Palette**: The **Upscale** preset opens the interactive Upscale dialog to select models, scale factors (2× to 4×), preview output resolution, and upscale directly.
   - **Settings → Presets**: The "Upscale Image" tool preset can be configured with preferred default models and scale factors.
   - **Settings → Engines**: "Upscayl (AI image upscaler)" engine package provides the local `upscayl-bin` binary, with models downloaded on demand with live progress and uninstall support in the Upscale dialog.
 - **Supported formats**: PNG, JPG, WEBP, ICO, HEIC, AVIF, BMP, and TIFF.
