Image and video utilities
Lesson 5.4 of 45 Video 1 min read Updated Oct 14, 2026
Resize, flip, build a grid, get the colour palette or extract frames: small pieces you then chain in a workflow.
Besides the AI models, WowMachine has dozens of utilities for everyday jobs. They run like any model, cost credits like any model and can be used as steps in a workflow.
The most used
Image: resize (resize-image), convert format (convert-image), crop (crop-image), compress (compress-image), flip (mirror-image), trim leftover transparency (trim-alpha-channel), image grid (image-grid), colour palette (color-palette) and PDF to images (pdf-to-images).
Video: download (video-downloader), trim a clip (extract-clip-video), merge videos (merge-videos), convert to GIF (video-to-gif), extract frames into a ZIP (extract-frames-zip), reverse (reverse-video), contact sheet (video-contact-sheet) and extract the audio (extract-audio-from-video).
They all live at /models/wowmachine/<name>/.
Step by step: a grid of variants
- Open Image Grid.
- In "Images", upload between 2 and 200 images.
- Adjust "Num columns" (3 by default), the space between cells in "Gap px" and the maximum width in "Max width".
- If you want labels, turn on "Add caption" for each file name or "Add index" to number them (#1, #2…).
- Check the cost on "Run" and start it.
When to use it
When a job is mechanical and always the same. If you repeat it often after another model, turn it into a workflow step and forget about it.
