## What it is
A fast, zero-dependency TypeScript parser for Adobe Photoshop PSD/PSB files that runs in web browsers and Node.js. It extracts layer information, pixel data, text layers, guides, and slices, using WebAssembly to accelerate image decoding.

## Use cases
- parse psd files in the browser
- extract layers from a photoshop file in node.js
- render psd composite image to canvas
- read text layer content from psd files
- support large psb files in a web app
- preview photoshop documents without photoshop
- get layer names and offsets from psd

## When to choose
- you need a lightweight (~100 KiB) PSD parser with zero dependencies
- you need to parse PSD/PSB files in both browsers and Node.js
- you need fast parsing with WebAssembly-accelerated image decoding
- you need unicode layer names, text layers, guides, or slices

## When to avoid
- you need full support for layer effects like shadows and overlays
- you need Photoshop metadata not directly related to the image
- you need to write or edit PSD files rather than parse them
- you need Internet Explorer support

## Facets
- artifact type: library
- maturity: active
- function: parser, image-processing, developer-tools
- domain: files, image-processing, web-development, frontend
