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.
