DESCRIPTION
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
▌ ABOUT THIS WORKFLOW
─────────────────────
Every other "8K upscaler" on CivitAI requires SUPIR, RestoreFormer,
and ControlNet — a nightmare of custom node installations, broken
dependencies, and out-of-memory crashes.
This workflow uses ONLY native ComfyUI nodes.
Drop the JSON file in, hit Queue, get 8K. That's it.
★ No custom nodes to install
★ No OOM / VRAM crashes
★ Original colors & lighting 100% preserved
★ Full image — no stretching, no cropping (v5 mode)
★ Works on NVIDIA / AMD / Apple Silicon
▌ THE SECRET
─────────────
ESRGAN ×4 upscales your image from 1024px → 4096px, recovering
every fine detail. ImageScaleBy ×2 then scales proportionally to
~8192px — no stretching, no cropping, no color shifts.
Original lighting and colors are 100% untouched.

PRO TIPS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
★ Best input: start with at least 512×512px. Higher input
= better 8K output detail.
★ Portrait photos: use v5 (Original) — ScaleBy preserves
the full portrait without any face cropping.
★ Wallpapers & landscapes: use v4 (Fill) — crops to a
perfect 16:9 8K for your display.
★ Low VRAM (4GB)? Downscale your input to 512px before
running. ESRGAN still outputs beautiful 8K results.
