I’m looking for a developer who can build a lightweight, self-contained upscaling script that runs entirely in PHP. Users will mostly upload photos, then choose how large they want the result—any custom resolution, well beyond 8 K if the server memory allows—and receive a high-quality JPEG back. No AI engines, no third-party APIs, no Python dependencies; it must work on ordinary shared hosting or a small VPS using standard PHP extensions such as GD or Imagick. Here’s what I need delivered: • A single-folder PHP application (plus any helper assets) that I can drop onto a server and start using from a browser. • Front-end form for image upload, percentage or absolute-pixel scaling, and a quality slider for the JPEG output. • Back-end logic that preserves sharpness and minimizes artifacts when enlarging photographs, employing best-practice resampling techniques available in native PHP. • Clear setup notes and a brief README explaining any memory limits, php.ini tweaks, or extension requirements. I’ll consider the job complete when I can load the tool on my test shared host, upscale a sample photo to a custom resolution, and receive a crisp JPEG without errors or external calls in the logs.
