ON1 Resize AI 2023.1 is a professional-grade image lossless enlargement software designed specifically for Mac users. Its core is based on artificial intelligence algorithms, capable of significantly increasing image resolution while intelligently preserving details, textures, and edge sharpness, effectively avoiding the blurriness and jagged edges caused by traditional interpolation enlargement. It can run as a standalone application or seamlessly integrate as a plugin into Adobe Photoshop and Lightroom, making it a powerful tool for photographers and designers handling large-format output (such as prints, posters, and art microspray).
I. Detailed Explanation of the Core Interface and Workspace
After launching ON1 Resize AI, the main interface layout is clear, primarily divided into the following functional areas:
- Top Menu Bar and Toolbar: Contains all file operations (open, save, export), editing tools (crop, rotate), view controls, and settings options.
- Left Panel – “Presets” Panel: Provides a rich set of predefined output size presets, such as common print sizes (4×6, 8×10), standard poster sizes, social media sizes, etc. Users can apply them with one click to quickly set target dimensions.
- Right Panel – “Adjust” Panel: This is the core control area of the software, including:
- Size Panel: Precisely set the output image’s width, height, resolution, and units. Aspect ratio can be locked.
- AI Model Selection: Offers a variety of AI upscaling models such as “Standard,” “Portrait,” and “Architecture & Landscape,” with algorithms optimized for different image content.
- Detail & Noise Reduction Sliders: After upscaling, you can fine-tune the sharpening level and suppress potential noise artifacts.
- Metadata & Watermark Settings: Manage EXIF information and add copyright watermarks.
- Central Viewing Area: Displays the image currently being edited. Offers multiple viewing modes, such as a “Original/Result Comparison” split-screen view, single-image view, and a “100% View” for pixel-level inspection.
- Bottom Status Bar: Shows the original and output dimensions of the current image, zoom ratio, and view zoom controls.
II. Complete Workflow: From Opening to Exporting
Step 1: Create/Open a Project
Method 1: Standalone Launch Click the ON1 Resize AI icon in the Dock or Applications folder to launch the software. On the welcome screen, click “Open Image,” or use the menu bar File > Open... (shortcut ⌘+O) to select one or multiple images.
Method 2: Launch as a Plugin from Other Applications In Photoshop, access it via Filter > ON1 > Resize AI 2023.1; in Lightroom Classic, right-click a photo and select Edit In > ON1 Resize AI 2023.1.
Step 2: Choose an AI upscaling model and adjust parameters
- In the “AI Model” drop-down menu in the “Adjustments” panel on the right, select the most suitable model based on the image content. For example, choose the “Portrait” model for portrait photos.
- Enter the target dimensions in the “Size” section. You can:
- Directly enter the width and height values and resolution (e.g., 300 PPI).
- Double-click a preset in the “Presets” panel on the left (e.g., “Print 16×20 inches”).
- Use the “Percentage” slider to scale proportionally (e.g., 200%).
- (Optional) Adjust the “Detail” slider to enhance edge sharpness, or use the “Reduce Noise” slider to smooth over-sharpened areas.
At this point, the central viewing area will display a real-time preview of the upscaling effect. It is highly recommended to use “Split View” (shortcut Y) or press the F key to quickly switch between the before and after effects to evaluate the AI processing quality.
Step 3: Make final adjustments and crop
If you need to recompose the image:
- Click the “Crop” tool in the toolbar (or press the
Ckey). - Drag on the image to create a crop box; you can constrain the aspect ratio. Press
Enterto apply the crop once confirmed.
Step 4: Export the final image
After completing all adjustments, click the bottom-right corner of the interface or go to File > Export... in the menu bar (shortcut ⌘+E).
- In the export dialog that appears, configure:
- Export location: Choose the destination folder.
- File format: Typically choose TIFF (lossless quality) or JPEG (for web sharing).
- Color space: Adobe RGB is recommended for printing, sRGB for web.
- Renaming and metadata options.
- Click the “Export” button to complete the process.
If launched from a Photoshop or Lightroom plugin, typically use the “Apply” or “Save” button to send the processed image directly back to the host application.
III. Advanced Tips for Common Features
- Batch processing workflow: In the standalone version, after opening multiple images, the settings in the right-side adjustment panel will automatically apply to all selected images. You can use the “Sync” button to ensure all photos have consistent parameters, then batch export via the “Export” dialog.
- Once you have configured a set of commonly used dimensions and AI parameters, you can click the “+” at the top of the right panel to save them as a custom preset for easy one-click access in the future.
- Extreme upscaling strategy: For cases requiring extreme enlargement (e.g., over 1000%), it is not recommended to do it in one step. You can adopt a “stepwise upscaling” strategy: first upscale by 200%-300%, export as TIFF, then re-import the TIFF file and upscale again, repeating this process—sometimes this yields better cumulative detail results.
- Integration with Photoshop Workflow: After completing AI upscaling in Resize AI, export as PSD or TIFF and refine in Photoshop (e.g., local retouching, color grading). This ensures detailed editing at the highest resolution.
IV. Common Issues and Solutions
| Symptom | Possible Cause | Solution |
|---|---|---|
| Halos or artifacts appear on image edges after processing | The AI model over-enhances edges, or the original image itself has high-contrast edges. | Try switching to a different AI model (e.g., from “Standard” to “Landscape”); moderately reduce the “Detail” slider value; increase the strength of the “Reduce Artifacts” slider. |
| Faces or textures look overly “plastic” after upscaling | The “Portrait” model may over-smooth skin textures in some cases. | Try using the “Standard” model; or after applying the “Portrait” model, slightly increase the “Detail” slider to recover some texture. |
| Software runs slowly or preview lags | Processing extremely high-resolution images (e.g., after upscaling medium-format files) places high demands on GPU/memory. | Ensure “Use GPU Acceleration” is enabled (check in “Settings”); close other large applications; try lowering preview quality to speed up response. |
| Exported image dimensions do not match settings | The “Crop” tool’s effect may have been overlooked, or there is an error in resolution unit (PPI) conversion. | Check whether an unintended crop was applied; confirm that the combination of dimension units (inches, centimeters) and resolution (PPI) meets your physical output requirements. |
