ON1 Resize 2021.5 is a professional lossless image enlargement software designed specifically for macOS, built on the industry-leading Genuine Fractals technology. It can enlarge digital photos to massive sizes (such as poster or billboard scale) while maintaining excellent clarity and detail. This guide will provide a detailed introduction to its interface, complete workflow, and practical tips.
I. Detailed Overview of the Core Interface and Workspace
After launching ON1 Resize 2021.5, the main interface is divided into the following core areas:
- Top Menu Bar and Toolbar: Contains commonly used function buttons such as file operations, editing tools, and view controls.
- Left Panel Area: Displays the “Folders” browser by default, used for navigating and selecting local image files.
- Central Viewing Area: The main area for image preview and editing, where you can switch between “Before/After” comparison views.
- Right Panel Area: Core function modules are concentrated here, including:
- “Adjust” Panel: Provides parameters such as size settings, algorithm selection, sharpening, and noise reduction.
- “Presets” Panel: Built-in presets for various output sizes (such as “Poster Size,” “Social Media,” etc.).
- “Details” panel: used for fine-tuning sharpening, reducing noise, and restoring detail.
II. Complete Workflow: From Opening to Export
1. Create/Open a Project
Step 1: After launching the software, you can import an image in any of the following ways:
- Click the menu bar “File” → “Open” (shortcut
⌘+O) to select a single image. - In the “Folders” panel on the left, navigate to the target directory and double-click the image thumbnail.
- Drag an image file directly from Finder into the central viewing area.
Step 2: Once the image is loaded, the central viewing area will display the original image, and the right panel will automatically activate the “Adjust” options.
2. Set Output Dimensions and Algorithm
Step 1: In the “Dimensions” section of the “Adjust” panel on the right:
- Enter the target values in the “Width” and “Height” fields; units can be pixels, inches, centimeters, etc.
- Check “Lock Aspect Ratio” to keep the proportions unchanged.
Step 2: Select an upscaling technology from the “Algorithm” drop-down menu:
- “Genuine Fractals 6”: the default recommendation, suitable for most photos, preserving detail and texture.
- “Traditional Interpolation”: Offers traditional algorithms such as “Bilinear” and “Bicubic,” which are faster.
Step 3: If you need to quickly apply preset dimensions, click the target preset in the “Presets” panel (e.g., “24×36 inch Poster”).
3. Detail Optimization
Step 1: Switch to the “Detail” panel:
- Sharpening: Adjust the “Amount” and “Radius” sliders to enhance edge clarity (recommended to fine-tune after zooming in).
- Noise Reduction: If the original image has noise, use the “Luminance” and “Color” noise reduction sliders to control it.
Step 2: In the central view area, use the Zoom Tool (Z) to inspect local details, and press the Spacebar to temporarily switch to the Hand tool for panning the view.
4. Export the Final Image
Step 1: Click the menu bar “File” → “Export” (shortcut ⌘+E).
Step 2: Configure the settings in the export dialog:
- Format: Choose TIFF, JPEG, or PNG.
- Color Space: Typically keep sRGB, or select Adobe RGB based on your output requirements.
- Rename: Optionally add a prefix/suffix.
- Destination Folder: Specify the save location.
Step 3: Click the “Export” button, and the processing progress will be displayed in the status bar at the bottom.
III. Advanced Tips for Common Features
- Batch Processing: Select multiple images in the left panel (hold
⌘and click), adjust the parameters and apply them to all selected images, and batch export when exporting. - Create Custom Presets: After setting the parameters in the “Adjust” panel, click the “+” icon in the upper right corner of the “Presets” panel to save it as a personal preset for reuse.
- Non-Destructive Editing: All adjustments are non-destructive, and you can go back and modify them at any time. The history is located in the “Window” → “History” panel.
- Integration with the ON1 Ecosystem: You can send images to ON1 Photo RAW for further adjustment via the menu “File” → “Edit in ON1 Photo RAW”.
IV. Common Problems and Solutions
Problem 1: Blurry edges or halos appear after enlarging the image
Solution: Try switching the algorithm to “Genuine Fractals 6”, and appropriately reduce the sharpening radius in the “Details” panel (for example, set it to 0.8-1.2) to avoid over-sharpening.
Problem 2: Exported files are too large
Solution: If exporting as TIFF, try using LZW compression; if it is not for print use, you can switch to JPEG format and adjust the quality slider (85%-95% is recommended).
Problem 3: The software runs slowly or lags
Solution: Make sure your system meets the minimum requirements (macOS 10.13 or later). Try lowering the “Cache Size” or disabling “GPU Acceleration” in “Preferences” (⌘+,) → “Performance”.
Problem 4: Unable to open by dragging and dropping files
Solution: Check whether the file format is supported (such as JPEG, TIFF, RAW, etc.). Try restarting the software or importing via “File” → “Open”.
