Tile-Upscaler

What it does

Splits an image into tiles, enlarges each one and stitches them back together, which lets it handle pictures too large for single-pass upscalers and reach print resolution. The added detail is generated: patterns that were not there can appear, text turns into unreadable near-letters, and tile seams are sometimes faintly visible, so inspect the result at full size. Not suitable for records or evidence.
