About Image Upscaler
Create a larger image with careful browser-based resampling for display and layout work.
Upscaling creates more pixels but cannot recover detail that was never captured. Multi-step resampling and gentle sharpening can make enlarged graphics and photographs look cleaner than a basic stretch.
What the result contains
A separate result that enlarge images with high-quality resampling and sharpening. The source remains unchanged in the current browser session.
Supported formats
- JPG
- PNG
- WebP
How to use Image Upscaler
- Choose a source file in a supported format (JPG, PNG, WebP) and confirm the displayed file details.
- Prepare the available controls for this practical goal: Enlarge a small image for a layout mockup
- Run Image Upscaler and confirm that the new result matches the stated outcome before saving it.
- Check this known constraint before download: Upscaling cannot recover real detail that is absent from the source If needed, revise the settings and create another version from the retained source.
Practical example
Enlarge a small image for a layout mockup. Use a representative source, compare the output with the original, and keep the version that meets the destination's requirements.
When to use Image Upscaler
- Enlarge a small image for a layout mockup
- Create a higher-pixel export for screens
- Resize an asset while keeping proportions
Important limitations
- Upscaling cannot recover real detail that is absent from the source
- Large scale factors can make blur or compression artifacts more visible
Troubleshooting Image Upscaler
The result is different from what you expected
Upscaling cannot recover real detail that is absent from the source Return to the retained source, adjust the relevant setting and create a fresh result rather than repeatedly processing the output.
