Image Upscaler
This lesson is part of Web Developer Tools · All levels
Summary
Image upscalers magnify image resolution, both with classical interpolation and artificial intelligence models. AI-based tools try to add details that seem reasonable, but those details remain estimated and can create artifacts. Upscaling is useful for old or small images, but it's not a way to recover completely lost information.
Key points
- Upscale adds the number of pixels to a factor like 2x or 4x
- The interpolation method produces a more subtle image but does not add to the original detail
- AI models can create textures and faces that don't exist at the source.
- Check the artifacts on the edges, text, and fine-textured areas
- Always compare the results to the original image at 100% scale.
