Basic Image Upscaler
Increase the pixel dimensions of an image using your browser's built-in high-quality image smoothing.
About this basic image upscaler
Need an image a bit larger for a specific use? This tool enlarges your image using smooth, high-quality interpolation, right in your browser.
How basic image upscaler works
The image is redrawn at a larger size (1.5x, 2x, or 3x) using your browser's high-quality image smoothing, which softens the enlargement compared to a plain nearest-neighbor resize.
Common uses
- Modestly enlarging a small image for a slightly larger display size
- Scaling up a graphic before placing it in a layout
- Increasing image dimensions for a specific minimum-size requirement
How to use this tool

- Click Upscale.
- Download the enlarged image.
What to know before using it
This performs a basic smoothed resize, not AI super-resolution, so fine detail that is not already present in the original image will not be invented. It is best for modest size increases rather than dramatic enlargements of low-resolution source images.
Privacy and browser-first processing
Your image is processed entirely inside your browser tab and is never uploaded to this server or any AI image service.
Frequently asked questions
Will this make a blurry, low-resolution photo sharp?
No, it smooths the enlargement but cannot invent detail that was not in the original image. For a genuinely low-resolution source, enlarging it will still look soft, just less blocky than a basic resize.
Is this the same as AI upscaling tools?
No, those use machine learning models to generate plausible new detail. This tool uses your browser's built-in smooth scaling, which is faster and fully private but more limited.
