How it works: Your browser upscales images using Canvas 2D with high-quality bicubic interpolation. Multi-step smoothing processes in 2x passes for large scale factors, reducing aliasing and giving cleaner results. No images are uploaded to any server.

Image Upscaler enlarges a small image while keeping it looking clear. Increase the size of a photo when you need a bigger version for printing or display, without the heavy blur you get from a plain stretch.

How to upscale an image

  1. Upload the small or low resolution image.
  2. Choose how much larger you want it.
  3. Start the upscaling.
  4. Download the enlarged image.

Why upscale a picture

Sometimes the only copy you have is small, but you need it bigger for a banner or a print. Upscaling adds size while working to keep edges and detail clean, so the larger image still looks good.

What to expect

Results depend on the starting image. A clear small photo upscales better than a blurry one. Upscaling improves the size and smoothness, but it cannot invent detail that was never captured.
