FliFlik KleanOut for Photo is an intelligent image cleaning and optimization tool designed specifically for macOS. Its core function is to help users quickly and accurately remove unwanted objects, people, blemishes, or any distracting elements from photos, and intelligently fill in the removed areas through advanced algorithms, making the repaired image look natural and seamless. This guide will provide an in-depth analysis of its interface, workflow, and usage tips.

I. Detailed Explanation of the Core Interface and Workspace

After launching the software, you will see a clean, feature-focused single-window interface, mainly divided into four core areas.

Top Menu Bar and Toolbar: Contains all file operations (open, save, export), editing tools (brush, eraser, zoom), and processing parameter settings. The toolbar icons are intuitive, with tooltips appearing on mouse hover.
Left Tool Panel:
- Selection Tool: Used to precisely frame the objects to be removed.
- Brush Tool: The main masking tool, used to mark areas to be deleted (highlighted in red by default).
- Eraser Tool: Used to correct markings that cross boundaries or were made by mistake.
- Zoom and Hand Tools: Used to browse image details.
Central Canvas Workspace: This is the core area for image display and editing. You make masking marks here and preview the processing results in real time. Supports dual-view mode (before/after comparison).
Right-side Parameters & History Panel:
- Brush Size/Hardness: Adjust the stroke of the painting tool.
- Processing Strength/Algorithm Mode: Choose different repair algorithms to suit different scenarios (e.g., texture smoothing, complex backgrounds).
- History: Records every operation step, allowing you to roll back to any step at any time.

II. Complete Workflow: From Opening to Exporting

The following are the complete steps for processing a photo with KleanOut from scratch.

Step 1: Create/Open a Project

Method: After launching the software, click the “Open” button in the toolbar, or use the shortcut Command (⌘) + O to select the target image file from Finder (supports common formats such as JPG, PNG, TIFF, etc.). The image will automatically load into the central canvas.

Step 2: Mark the Objects to Be Removed

Select the “Brush Tool” in the left toolbar (or press the shortcut B).
In the right panel or the top toolbar, adjust the brush size (you can use the shortcuts [ to shrink and ] to enlarge) and hardness.
On the central canvas, carefully paint over the objects you want to remove. The painted area will be covered with semi-transparent red. For fine edges, it is recommended to reduce the brush hardness; for large areas, you can increase the brush size.
If you mark an area incorrectly, switch to the “Eraser Tool” (shortcut E) to erase and correct it.

Tip: For regular or large-area objects, you can first use the “Selection Tool” (such as Rectangle or Lasso) to make a selection, then click the “Fill Mark” button in the toolbar to quickly generate the inpainting area.

Step 3: Apply Smart Cleanup

After marking is complete, click the “Process” button in the top toolbar (the icon is a play button), or use the shortcut Command (⌘) + R. The software will begin analyzing the image, automatically removing the marked objects and intelligently filling in the background. Processing time depends on the image size and the complexity of the marked area.

Step 4: Review and Fine-Tune

After processing is complete, carefully inspect the repaired area on the canvas. The software usually provides a “before/after” comparison slider (located above the canvas); drag it to view the result.
If you are not satisfied with the result, you can use the “History” panel on the right to revert to the “before processing” state (shortcut Command (⌘) + Z allows step-by-step undo).
For localized blemishes, you can repeat Steps 2 and 3 to perform a second round of small-scale marking and cleanup.

Step 5: Export the Final Image

Once you’re satisfied with the result, click “File” -> “Export” in the menu bar, or use the shortcut Command (⌘) + E directly.

In the dialog that appears, choose the save location and file name for the exported file.
Select the desired image format (e.g., JPEG, PNG).
Adjust format-specific parameters as needed (e.g., JPEG quality).
Click the “Export” button to complete the operation.

III. Advanced Tips for Common Features

Non-destructive editing: All markings and processing steps are recorded in the history panel. You can go back to any step at any time to make changes without damaging the original image data.
Multi-region batch processing: You can mark multiple non-adjacent objects in an image at once, then execute a single processing command, and the software will process all marked regions simultaneously, boosting efficiency.
Strategies for complex backgrounds: For backgrounds with complex textures (e.g., grass, brick walls) or with a sense of perspective, if a single pass doesn’t produce good results, you can try:
- Switching between different “algorithm modes” in the right panel.
- Dividing a large region into multiple smaller regions and performing detailed marking and processing in multiple passes.
Keyboard shortcut workflow: Proficient use of keyboard shortcuts can greatly improve efficiency. For example: B (brush) -> paint -> Command+R (process) -> Command+S (save) or Command+E (export).

IV. Common Issues and Solutions

Symptom	Possible Cause	Solution
Blurry or distorted textures appear in the processed area	1. The marked area is too large or contains complex textures. 2. The selected algorithm mode does not match.	1. Reduce the processing area per operation and process in multiple passes. 2. Try different “repair algorithm” options in the right panel. 3. Use “History” to undo, and re-mark the object edges with a more precise brush.
The software responds slowly when painting	The resolution of the opened original image is too high.	For very large images, you can first use the zoom tool (`Z`) in the preview stage to zoom in to the local area you need to process, or consider reducing the resolution appropriately in external software before processing.
Unable to completely erase red markings	The eraser tool size is set improperly, or the hardness is too high.	Press `]` to increase the eraser size, and lower the eraser hardness in the right panel for gentle erasing.
Exported image quality degrades	A format with high compression was selected during export (such as low-quality JPEG).	Choose a lossless format such as PNG when exporting, or make sure the JPEG quality slider is adjusted to 90% or above.
