About AI Image Upscaler — Free Online Tool
Image Upscaler enlarges a picture by a factor you choose, from 1.1x up to 8x, by interpolating new pixels between the ones already there.
The enlargement runs in doublings so the resampler works over a short distance each time instead of one long stretch, which avoids the mush a single big jump produces, and a light unsharp mask afterwards restores some of the edge contrast interpolation always costs. This is resampling, not super-resolution: no model is involved, no texture is synthesised, and a soft or low-detail source comes out bigger and exactly as soft. Reconstructing detail that is not in the file needs a trained network, which this site does not run.
The resampling and the sharpening pass both happen on your device; nothing is sent to an upscaling API.
Meeting a minimum pixel dimension a form or a print service insists on, scaling simple artwork up for a banner, enlarging a crop so it fills a layout, and getting a flat graphic to a bigger size without redrawing it.

When to use it
The honest use for it is dimensional: clearing a pixel minimum that an upload form or a print shop will not budge on, filling a wider layout from a crop, or taking a flat graphic up to banner size.
How it works
The scale factor is reached in stages. The canvas is redrawn at double its size as many times as fit, then one final draw lands on the exact target, so each interpolation step stays short. One unsharp mask pass runs over the enlarged pixels at the end, so edges do not read as soft as plain interpolation leaves them.
What Enlarging Can And Cannot Do
Because every new pixel is a weighted average of its neighbours, a logo or a line drawing stays clean at a larger size — and a photograph that was already soft comes out just as soft, only bigger. Getting back detail the camera never captured needs a trained super-resolution network, and there is no such model on this site.
