Understanding Image Interpolation
What is Image Upscaler?
Image upscaling is the process of increasing the resolution of a digital image. Since expanding the pixel matrix leaves gaps, interpolation algorithms are required to compute the color properties of new pixels based on surrounding pixels.
How to use the Image Upscaler tool?
- Upload Image: Select or drag and drop your image file (PNG, JPG, WebP) into the upload area.
- Configure Settings: Use the sliders, buttons, or select menus to rotate, adjust, or compress your image as desired.
- Live Preview: View the real-time visual changes instantly in the high-fidelity preview panel.
- Export: Click the export button to download the processed image at full resolution locally to your device.
