Image Upscaler

Upscale images smoothly up to 4x using browser interpolation. Great for small icons, thumbnails, or low-res photos that need a boost.

Drag & drop an image, or click to choose

Scale

Higher scale = larger file. Use 2x for icons, 4x for small prints.

Your image is processed entirely in your browser. It is never uploaded to our servers and never leaves your device.

  2. Select a scale factor: 2x, 3x, or 4x.
  3. Press Upscale to apply smooth interpolation.

About this tool

Upscaling is done using canvas interpolation, which blends nearby pixels to create a smoother, larger image. It works best on illustrations, screenshots, icons, and clean photos — not heavily compressed JPEGs with block artifacts.

When to use it: make small logos printable, enlarge thumbnails for presentations, or prepare icons for high-resolution displays.

Frequently asked questions

Will this make a blurry photo sharp?
No — upscaling enlarges pixels smoothly but cannot recover lost detail. It is best for images that are already clear but too small.
Can I edit after upscaling?
Yes — press Reset anytime to return to the original. You can also upload a new image at any time.
What is the maximum file size?
There is no hard server limit because everything runs locally. Very large images may take a moment to process depending on your device.

How to use Image Upscaler

Upload your image to the Image Upscaler canvas by dragging or clicking. Configure settings such as quality, dimensions, or filter options as needed, then start processing. The output renders in the same tab and can be saved directly.
