## What it is
Gowall is a Go-based CLI tool that converts images (especially wallpapers) to custom color schemes and offers a broad suite of image processing features. It includes OCR with traditional and VLM-based providers, AI image upscaling, compression, palette extraction, background removal, and terminal image preview.

## Use cases
- recolor a wallpaper to match catppuccin or a custom theme
- extract text from images and pdfs with ocr
- compress png jpeg webp images from the command line
- upscale low resolution images with ai
- extract the dominant color palette from an image like pywal
- convert an image to pixel art
- remove the background from an image
- convert images between formats like webp to png

## When to choose
- you want a fast single CLI for many image processing tasks instead of separate tools
- you need to recolor wallpapers or icons to match a specific color scheme
- you work in the terminal and want unix pipe support and image preview
- you need flexible OCR with multiple providers including VLMs

## When to avoid
- you need a full GUI image editor with layers and manual editing
- you require fine-grained professional photo retouching controls
- you need batch processing pipelines with complex scripting beyond simple CLI usage
