Upscaling Image 1.5x Online: Precise Image Enlargement with AI at UpscaleIMG.AI


Upscaling by 1.5x means increasing your image’s width and height by 50%—resulting in 1.5 times the original pixel count. For example:
Original Size | 1.5x Upscaled Size |
800 × 600 px | 1,200 × 900 px |
1,000 × 500 px | 1,500 × 750 px |
400 × 300 px | 600 × 450 px |
Upscaling to 1.5x strikes the perfect balance between too small and unnecessarily large images, providing crisp detail without excessive file sizes.
- Responsive design needs: Many devices or webpage grid systems require sizes between 1x and 2x for ideal display.
- Exact print dimensions: Avoid awkward cropping by matching design specs exactly.
- Optimized file size: A 1.5x image avoids the bloat of 2x or 4x images, which can slow websites.
- Sharper visuals: AI-powered upscaling creates new detail, avoiding pixelation common in simple resize tools.
- Better user experience: Faster page loads and sharp visuals contribute to higher engagement and SEO benefits.
Unlike traditional resizing methods that stretch existing pixels leading to blur and artifacts, AI upscaling at UpscaleIMG.AI uses deep learning:
- Trained AI models analyze millions of images to learn how to generate new pixels realistically.
- Content-aware enhancement restores texture, edges, and details based on context.
- You get images larger and crisper, not merely “bigger.”
This technology allows perfectly clear 1.5x scaling with smooth surfaces and sharp edges intact.
