ComfyUI-YCNodes

Rotate through 10 images — randomly, cyclically, or by index

A fixed lookup table that maps an input number to a CFG — know what you're getting

Pad an image to a target ratio — and get the mask that proves what's original

Pull one named image out of a batch — without counting frames

Drop a foreground onto a background by telling it WHERE — a mask does the locating

Place, scale, rotate, and blend one image onto another — with the mask to show it

Stitch two images into one canvas for in-context LoRA work

The in-context combiner with pixel-level control — overlay, XY placement, and the main image on its own

Load an image and its alpha mask in one shot — blur and strength built in

Mirror an image — yes, it's really that simple

Pixelate a face (or anything) without a trip to Photoshop

Scale an image and its mask as one unit — then hand the original size back so you can restore it

Pick the keeper out of an 8-image batch — stop upscaling the other seven

Pick a latent size that actually matches your image's aspect ratio

Tile upscale without nuking your VRAM

Turn a messy hand-drawn mask into a clean, regular shape

Load a whole folder of images — single, batch, random, or stepping through one by one

Staple two mask batches together — despite the name, it's concatenation, not blending

Duplicate a mask batch into two outputs — the splitter you didn't know you needed

Stamp one mask onto another at any position — with multiply, XOR, overlay, and friends

Fill in a line-art or outline mask so it becomes a solid region

Stitch a cropped, edited image back onto its background — the 'restore' half of crop-edit-stitch

Crop exactly around a mask — padding, multiple-of-8 sizing, and a live preview of the box

Keep the solid blobs, drop the fragments — filter masks by how convex they are

The mask slicer ComfyUI core forgot

Actually look at your mask — a preview node that doesn't fake it with black boxes

One mask, a batch of frames — repeat it to match

Pad your mask's content out to a clean aspect ratio — no canvas resize involved

Split a joined mask along its waist — where two blobs are fused, cut the valley

Explode a multi-object mask into one mask per object

Keep the N biggest blobs in a mask, delete the rest

Strip (parenthetical noise) out of your prompt — full-width brackets included

Grab everything before (or after) a keyword — for filenames, tags, and prompt surgery

Fit any batch of images inside max width/height — and know it's a list coming out

Pull the leading number out of a string — the tiny logic helper that saves a regex node

Five text boxes, one node — write your prompt in parts and get the join for free

Batch up every generation, then pick the winner after

A save node that actually names your files and writes captions too

Crop an image and get the map of where you cropped it

Pad a canvas and get a mask of the new border — your outpainting starts here

Split a big image into overlapping tiles — the cheap ticket to upscaling past VRAM

One image, repeated into a contact sheet — the node for 'show me all the variants' boards

Stitch tiles back into a full image — the other half of tiled upscaling

Feather your masks before they hit the sampler — the difference between a seam and a blend

Paint your mask onto the image — the fastest way to see (and abuse) what you're masking

Route between two masks based on a text match — a tiny switch for loop workflows

Grow a mask in one direction without wrecking the other

Center your subject in a ratio-perfect frame — pad, crop, and hand back every mask you need

Stretch a dim mask up (or pull a hot mask down) — simple range surgery for masks

Give every iteration of a loop its own seed — deterministic batch variety

Just a text box — the node you didn't know you wanted

A ten-slot LoRA switcher you can chain — and it only loads the LoRA you picked

Pick between two images based on a text match — the loop workflow's cheap branch

Render text to an image (and its mask) without ever leaving ComfyUI

Pick one of 12 prompts with an index — and only compute that one

Find-and-replace for your prompt, up to three swaps deep — dead simple, occasionally perfect

A pass-through gate for ANY data type, opened by a text condition — including a not-switch
