Why do we need a tool to increase image resolution? Practical applications

In many situations, you need a higher resolution image than the original image. When printing large-format photos (posters, banners, backdrops), low-resolution photos will be grainy, blurry, and not beautiful. When cropping a small part of an image to make an avatar or thumbnail, the crop is often too small and needs to be enlarged. When restoring old photos, scans from film, photos taken from old phones with low resolution, they need to be upscaled for use. In graphic design, many times clients send low-quality images but require large-format printing. In e-commerce, product images need high resolution for customers to zoom in to see details. This tool uses an interpolation algorithm combined with unsharp mask - suitable for basic needs. For photos that require higher AI quality (Real-ESRGAN, GFPGAN for portraits), you can try professional services like Replicate or Upscale.media.
