Upscale Image

What is Image Upscaling?

Image upscaling enlarges low-resolution photos using AI or algorithms to produce higher-resolution images. It's used for printing or large-screen display.

PdfMetric's upscale tool can run in the browser or cloud. Check how your data is processed; security and privacy matter.

When Should You Use It?

  • Printing: Enlarge small images for posters or prints
  • Web: Increase resolution for Retina/4K displays
  • Archiving: Improve old low-res photos
  • E-commerce: Make product images large enough for zoom

Advantages

  • AI-based: Intelligently infers details
  • 2x–4x scaling: Size options available
  • Anti-aliasing: Reduces pixelation
  • Easy to use: One-click processing

Frequently Asked Questions

AI interpolation generates similar textures but details are inferred, not from the original. Usually sufficient for natural-looking results.

Pixel count increases 2x–4x; file size grows similarly. Can be controlled with compression settings.

How to Use

  1. Upload image: Select the low-resolution image to upscale.
  2. Choose scale factor: Pick 2x, 3x, or 4x.
  3. Process: Start the AI or algorithm process.
  4. Download: Download the upscaled image.

Tip: Very small source images (e.g. 100x100) may produce blurry results.
