# ComfyUI-SmartResize
|
|
|
|
Smart image resize nodes for ComfyUI — batch processing, LoRA prep & SeedVR support.
|
|
|
|
All nodes appear under the **Craftopia** category in the node menu.
|
|
|
|
---
|
|
|
|
## Nodes
|
|
|
|
### 📐 Smart Resize
|
|
Resize any image (or batch) so the **longest side** equals `max_pixels`, with aspect ratio preserved.
|
|
|
|
Use this as a **pipeline node** — IMAGE in, IMAGE out. No files are saved to disk.
|
|
|
|
**Typical usecases:**
|
|
- Downscale a SeedVR (or other upscaler) result back to your target training size — the upscaler adds fine detail, Smart Resize brings it to the right dimensions for LoRA training
|
|
- Any workflow step that needs a clean resize before the next node
|
|
- Normalize mixed-resolution batches to a consistent size
|
|
|
|
| Input | Type | Default | Description |
|
|
|---|---|---|---|
|
|
| image | IMAGE | — | Single image or batch |
|
|
| max_pixels | INT | 1536 | Target size for longest side |
|
|
| multiple_of | INT | 8 | Snap dimensions to this multiple (8 = SD/Flux compatible) |
|
|
| interpolation | ENUM | lanczos | lanczos / bicubic / bilinear / nearest |
|
|
| upscale_if_smaller | BOOLEAN | false | Also upscale images already smaller than max_pixels |
|
|
|
|
**Outputs:** `image`, `width`, `height`
|
|
|

|
|
|
|
### 📁 Smart Batch Resize
|
|
Load **all images from a folder**, resize each one by longest side, and save with the original filename + a suffix into a subfolder. Original filenames are always preserved.
|
|
|
|
Use this for **bulk preprocessing** — e.g. preparing a LoRA dataset from a folder of high-res images.
|
|
|
|
| Input | Type | Default | Description |
|
|
|---|---|---|---|
|
|
| input_folder | STRING | D:/images/input | Source folder path |
|
|
| max_pixels | INT | 1536 | Target size for longest side |
|
|
| filename_suffix | STRING | _Small | Appended to each output filename before the extension |
|
|
| output_subfolder | STRING | resized | Subfolder created inside input_folder |
|
|
| multiple_of | INT | 8 | Snap dimensions to this multiple |
|
|
| interpolation | ENUM | lanczos | lanczos / bicubic / bilinear / nearest |
|
|
| skip_if_exists | BOOLEAN | false | Skip files that already exist in output |
|
|
|
|
**Outputs:** `images` (list), `filenames` (list), `output_paths` (list), `count`
|

### 📏 Smart Size Multiplier
|
|
Multiply image dimensions by a factor and output the results as integers.
|
|
|
|
SeedVR takes a single `resolution` INT (the longest side) — not a width and height separately. Standard math nodes give you a FLOAT or require multiple steps to get there. This node does it cleanly in one step: give it your image and a multiplier, and it outputs `width`, `height`, and `resolution` (longest side) ready to connect directly to SeedVR's `max_resolution` input.
|
|
|
|
Also useful for LoRA dataset prep — using mixed resolutions in your training set generally produces better results than training on a single fixed size. Smart Size Multiplier makes it easy to dynamically calculate the right target size per image rather than hardcoding a value.
|
|
|
|
| Input | Type | Default | Description |
|
|
|---|---|---|---|
|
|
| image | IMAGE | — | Source image |
|
|
| multiplier | FLOAT | 2.0 | Multiply width and height by this factor |
|
|
| multiple_of | INT | 8 | Snap dimensions to this multiple |
|
|
|
|
**Outputs:** `width`, `height`, `resolution` (longest side as INT → directly into SeedVR)
|
|

## Why these nodes?
|
|
|
|
- ComfyUI's built-in `Resize Images by Longer Edge` [BETA] has no Lanczos and no `multiple_of` snapping
|
|
- `JWImageResizeByLongerSide` (comfyui-various) has no Lanczos in the official release
|
|
- No existing node combines batch folder loading + longest-side resize + original filename preservation
|
|
- No existing node outputs a ready-to-use `resolution` INT for SeedVR

## Installation
|
|
|
|
**ComfyUI Manager:** search for `ComfyUI-SmartResize` and install.
|
|
|
|
**Manual:**
|
|
```bash
|
|
cd ComfyUI/custom_nodes
|
|
git clone https://github.com/CraftopiaStudio/ComfyUI-SmartResize
|
|
```
|
|
Restart ComfyUI. All nodes appear under **Craftopia** in the node menu:
|
|
|
|
- `Craftopia` → **Smart Resize 📐**
|
|
- `Craftopia` → **Smart Batch Resize 📁**
|
|
- `Craftopia` → **Smart Size Multiplier 📏**
