Image Upscaler User Guide
The Image Upscaler feature in UltraPic is designed to increase the resolution of your images.
Beyond simple resizing, this feature automatically:
Enhances image clarity
Sharpens blurry photos
Reduces noise
Improves overall image quality
If you are looking to convert low-resolution images into high-definition assets while solving issues like blurriness and graininess, this feature is your best choice!
Use Cases
The Image Upscaler is perfect for the following scenarios:
Social Media Assets: Upscaling small preview images into clear, high-quality posts.
E-commerce Product Images: Enlarging product photos while reducing noise and sharpening details for product detail pages.
Printing & Display: Upscaling lower-resolution photos to sizes suitable for small posters, brochures, or screen displays.
Design Asset Pre-processing: Upscaling assets to the required working resolution and improving base image quality before further editing.
Digitizing Old Photos: Upscaling scanned photos while reducing noise caused by scanning or compression, and moderately sharpening edges.
How to Use
Step 1. Upload the Image
Open UltraPic and find the “Image Upscaler” entry on the homepage or in the tools menu. Then upload an image.
There are three ways to upload an image:
1. Drag & drop: Simply drag your image directly onto the UltraPic main page.
2. Open Image: Click the "Open Image" button to select and upload a file from your device.
3. Sample images: If you don't have an image ready, you can click on one of UltraPic's provided samples to test the features.
Step 2. Select Upscaling Method
The feature offers two upscaling methods. You can choose either one based on your needs. Then choose "Start Upscaling." Wait a few seconds to a minute (depending on image size and server load).
By Dimensions: Directly set the target dimensions (in pixels).
You can specify the length of the longer side in pixels. The system will automatically calculate the shorter side based on the aspect ratio and scale the image to the specified size (the longer side will not exceed 3840 pixels).
By Scale: Set a magnification multiplier: 2×, 3×, 4×, 8×
When selecting a multiplier, both the height and width of the image will be multiples of the original dimensions.
Step3. Contrast
Drag the center line left or right to compare the difference before and after upscaling.

Step 4. Download
Once processing is complete, compare the original image with the result. If satisfied, click Download to save it to your local device.
You have two options for downloading your final image:
1. Direct Download: Click the download icon in the top-right corner of the image in your "Image History." The image will be saved to your browser's default download folder.
2. Custom Download: Click the main "Download" button in the top-right corner of the software to specify the image file name, format, and quality ect. before saving it to your computer.
Notes
Size Limit: The long edge of the upscaled image must not exceed 3840 pixels (the short edge scales proportionally).
When upscaling By Dimensions, if the set value exceeds the limit, the system will automatically adjust it down to the limit.
When upscaling By Scale, if the resulting long edge exceeds the limit, the system will scale it down to fit the limit.
Effect Scope: This feature provides "Upscaling + Light Intelligent Enhancement (Clarity, Sharpening, Denoising)." For heavy restoration (e.g., severe blur recovery, large-area noise removal, or AI detail repainting), we recommend using other professional enhancement tools in UltraPic, like Photo Retouching function.
Source Quality: If the original image is extremely low resolution (e.g., 64×64) or heavily compressed, the enhancement effect will still be limited by the amount of original information available.
Format & File Size: The output format defaults to the same as the original. Please note that file size will increase after upscaling and optimization.
Network Requirements: A stable internet connection is required for online processing. Uploading large original images may take some time.
Fine-tuning: When processing human faces or complex textures, it is recommended to check the preview and adjust sharpening parameters (if available) appropriately for the most natural visual experience.
FAQ
Q1: What is the difference between the two scaling methods? How should I choose between them?
A: By Dimensions: Suitable for scenarios with specific resolution requirements (e.g., when the long edge needs to be exactly 3000px).
By Scale: Suitable for simple scaling by a multiple (e.g., when you only need to scale the image to twice or three times its original size).
Both methods are ultimately limited by the 3840px maximum long edge.
Q2: What should I do if the scaling ratio I set doesn’t match the original image when enlarging it?
A: The system will maintain the original image’s aspect ratio and automatically calculate the other dimension based on the longer side (or shorter side) you specify. The image will not be stretched or distorted.
Q3: What magnification scales are supported?
A: It typically supports common multipliers like 2×, 3×, 4×, and 8×. Specific options are subject to the interface display. If the upscaled long edge exceeds 3840px, the system will automatically adapt to the limit.
Q4: Does Image Upscaler automatically perform noise reduction and sharpening?
A: Yes. While upscaling, the feature automatically reduces common noise, sharpens blurry edges, and improves overall image clarity and quality. No extra settings are required from the user.
Q5: Will upscaling also magnify the noise?
A: No. The algorithm actively reduces noise while performing the upscaling. Therefore, the final image is typically much cleaner than a direct stretch of the original image.
