Local AI image upscaling

A local Real-ESRGAN wrapper with explicit scales, batch processing, formats and separate output folders.

Workflow and wrapper by Simon Lin; underlying tools and models belong to their upstream projects.

01 / REQUIREMENTS

Before you start

Separately installed Real-ESRGAN executable and models; JPEG conversion needs macOS sips.

  • 2/3/4x scales and model option
  • Separate output; refuses overwrites
  • PNG or JPEG output

02 / INSTALL

Install and use

unzip image-upscale-v1.1.0.zip -d ./skill-install
mkdir -p "$HOME/.agents/skills/image-upscale"
cp -R ./skill-install/image-upscale/. "$HOME/.agents/skills/image-upscale/"

For Claude Code, use .claude/skills instead of .agents/skills. For other clients, follow their loading convention. Keep commands consistent with your actual install path, then read SKILL.md and THIRD-PARTY.md.

Run upscale.sh as described in SKILL.md. Inspect text, textures and any final print requirements.

No dependencies, model weights, accounts, authentication or media are bundled. Upstream services may have their own costs and usage limits.
