项目简介

PSD Editor 可以在浏览器中打开、编辑并导出 PSD / PSB 文档，也可以作为无头服务被脚本、自动化平台或 AI Agent 调用。

• 编辑器：图层、组、蒙版、混合模式、图层样式、文字、矢量路径、调整图层、滤镜、画板、色彩管理、选区、画笔、修饰、液化、消失点等。

• 智能对象导入：读取 Photoshop 保存的缓存像素，作为普通像素图层使用；不编辑内嵌源内容、放置网格或智能滤镜参数。

• 导出：PSD / PSB、PNG、JPEG、WebP、TIFF，以及 PDF、GIF、BMP、TGA、HDR、EXR 等格式。

• API：基于 Express 的 REST 接口，覆盖解析、编辑、渲染、导出、字体、档位与权限。

• MCP：标准 Model Context Protocol Streamable HTTP 端点，方便 Claude、Cursor、VS Code 等客户端接入。

• CLI：不启动浏览器即可执行 inspect、render、batch、convert 等操作，也可作为 stdio MCP 使用。

• 本地 AI：可选的“重新打光”功能，模型在浏览器本地推理，不上传图片。

本项目只保留 编辑器、MCP 服务、API 服务 三项核心能力，不包含官网、文档站、在线调试台或示例 PSD 下载入口。

0.14.0 更新了什么

• 大文件更好保存了：超大 PSD 的压缩和保存更多交给后台处理，减少卡顿和内存占用，保存后的预览图也会更新。

• 颜色更接近 Photoshop：改进渐变、调整图层，以及 CMYK、Lab、灰度和 16/32 位文档的显示与导出，减少打开后偏色的情况。

• 文字保存更完整：改进文字变形、路径文字和英文断字，保存后的排版和参数兼容性更好。

• 图层外观按缓存保留：智能对象按 Photoshop 已保存的像素导入，保留文档中的独立图层；合并大图层时如果读不到原图像素，会停止操作并保留原内容。

• 接口权限更严格：API Key 创建的会话沿用该 Key 原有的权限和额度。

升级后请重新安装依赖并运行 npm run build，再运行 npm start。默认启动现在使用生产模式；本机调试请用 npm run dev。

完整记录和已知限制见 更新日志。

智能对象与兼容性限制

导入智能对象后保留 Photoshop 保存的图层像素，不重新计算其内部源文档或变形。文档中的其他图层、文字和蒙版继续独立存在。导出的 PSD 不再包含这些智能对象的可编辑源内容；需要保留原始智能对象结构时，请保留原文件并另存编辑结果。

缓存缺失或通道数据不完整的文件可能无法正确显示或导入，应先在 Photoshop 中重新保存。溶解混合模式为近似效果；部分 HDR 调整、路径文字翻转及其他高级组合仍有限制。

环境要求

• Node.js >= 20.11.0

• npm

• 可选：Playwright + Chromium（运行浏览器测试）

• 可选：ImageMagick、Python 3 等（部分测试会使用）

安装

cd "PSD Editor"
npm install
npm --prefix server install

启动

npm run build
npm start

默认以生产模式启动，只提供构建产物。编辑器默认无需登录。PSD_EDITOR_KEY=1 是可选的服务端访问限制；启用时需由调用方或受控网关提供 API Key，页面不提供登录表单。

默认地址：

http://localhost:8787/

编辑器入口为 / 或 /editor。

开发模式（监听源码改动）：

npm run dev

本地调试时可以关闭 API 鉴权：

PSD_EDITOR_AUTH=off npm start

PSD_EDITOR_AUTH=off 只允许在本机或可信内网使用。部署到公网前必须配置 API Key、HTTPS 与反向代理。

配置

环境变量通过 shell、systemd、Docker 或进程管理器注入，.env.example 是完整变量清单模板。常用变量：

创建 API Key：

cp server/api-keys.example.json server/api-keys.json
# 编辑 server/api-keys.json，填入随机 key
npm start

创建档位配置：

cp server/plans.example.json server/plans.json

请求时通过请求头传入 Key：

X-Api-Key: your-key

或：

Authorization: Bearer your-key

REST API

常用端点：

示例：

curl http://localhost:8787/health

curl -X POST http://localhost:8787/api/doc/inspect \
  -H "X-Api-Key: your-key" \
  -F "psd=@example.psd"

curl -X POST http://localhost:8787/api/doc/edit \
  -H "X-Api-Key: your-key" \
  -F "psd=@example.psd" \
  -F 'ops=[{"op":"setLayerProps","index":1,"name":"新名称"}]'

完整参数请读取 /api/catalog 或 /openapi.json。智能对象在导入时转为缓存像素图层；不提供源图替换、网格编辑或智能对象片段写回接口。

MCP

MCP 端点为：

POST /mcp

客户端配置示例：

{
  "mcpServers": {
    "psd-editor": {
      "type": "http",
      "url": "http://localhost:8787/mcp",
      "headers": {
        "X-Api-Key": "your-key"
      }
    }
  }
}

本地 stdio MCP：

node bin/psd_editor.js mcp

CLI

node bin/psd_editor.js capabilities
node bin/psd_editor.js describe setLayerProps
node bin/psd_editor.js inspect example.psd
node bin/psd_editor.js render example.psd --out preview.png
node bin/psd_editor.js batch example.psd --input ops.json --out edited.psd
node bin/psd_editor.js convert example.psd example.png

本地 AI 模型

“重新打光”等功能使用本地 ONNX / MediaPipe 模型。仓库默认不提交大体积 .onnx 模型；如缺失可执行：

npm run vendor

该命令会下载并校验固定版本资源。所有推理均在本地完成，不上传图片。

测试

npm test

浏览器测试（需要 Playwright 与 Chromium）：

npm run test:browser

Overview

PSD Editor is a browser-based editor for PSD / PSB documents, with a REST API, an MCP server, and a local CLI. The PSD kernel is shared between the browser editor and the Node.js server.

Live demo: https://fullpsd.zaopod.com
GitHub repository: https://github.com/hmwl/psdeditor

This project is provided for learning, research, and technical reference only. You must comply with applicable laws, Adobe's license terms, and intellectual-property rules. Any illegal use is strictly prohibited. See the disclaimer below.

Features

• Open, edit, and export PSD / PSB documents.

• Layers, groups, masks, blend modes, layer styles, text, vector paths, adjustment layers, filters, artboards, selections, brushes, retouching, liquify, and vanishing point.

• Import smart objects as ordinary pixel layers using the cached appearance saved by Photoshop. Embedded source content, placement meshes, and smart-filter parameters are not editable.

• Export to PSD / PSB, PNG, JPEG, WebP, TIFF, PDF, GIF, BMP, TGA, HDR, EXR, and more.

• ICC color management and CMYK workflows.

• REST API for parsing, editing, rendering, export, fonts, plans, and permissions.

• MCP Streamable HTTP endpoint for Claude, Cursor, VS Code, and other clients.

• CLI for inspect, render, batch, convert, and stdio MCP.

• Optional local AI relighting. Inference runs locally; images are not uploaded.

The project ships only the editor, MCP service, and API service. It does not include the former marketing site, documentation site, online API console, or sample-PSD download endpoint.

What changed in 0.14.0

• Large files use improved background compression, streaming saves, and refreshed composite previews.

• Gradients, adjustment layers, and CMYK, Lab, grayscale, and 16/32-bit documents have better rendering compatibility.

• Text warping, path text, and English hyphenation preserve more layout information when saved.

• Smart objects import as cached pixel layers. The document keeps its separate layers; large-layer merges stop if the original pixels cannot be read.

• API-key sessions inherit the key's permissions and quotas.

Reinstall dependencies and run npm run build before npm start. See the changelog for details.

Smart objects and compatibility limits

Smart-object imports retain the layer pixels saved by Photoshop without recalculating embedded content or deformation. Other layers, text, and masks remain separate. Exported PSDs no longer contain editable smart-object sources; keep the original file and save your result separately if you need the original structure.

Files with missing caches or incomplete channel data may fail to display or import correctly; resave them in Photoshop first. Dissolve blending is approximate. Some HDR adjustments, flipped path text, and other advanced combinations still have limitations.

Tech Stack

• Node.js 20.11+

• Express 5, Sharp, Multer

• JavaScript PSD kernel with optional WASM acceleration, shared by browser and server

• Native ES Modules, Canvas, WebGL / WebGPU, Web Workers

• REST, OpenAPI 3.1, MCP Streamable HTTP

• Playwright for optional browser tests

• ONNX Runtime Web and MediaPipe Tasks Vision for local AI

Requirements

• Node.js >= 20.11.0

• npm

• Optional: Playwright + Chromium for browser tests

• Optional: ImageMagick, Python 3, and other tools used by some tests

Install

cd "PSD Editor"
npm install
npm --prefix server install

Run

npm run build
npm start

The server defaults to production mode and serves built assets. The editor opens without login by default. PSD_EDITOR_KEY=1 optionally restricts session creation at the server; the caller or a controlled gateway must provide the API key. The page has no login form.

Open:

http://localhost:8787/

Development mode:

npm run dev

For local testing without API authentication:

PSD_EDITOR_AUTH=off npm start

Never expose PSD_EDITOR_AUTH=off to the public internet. Use API keys, HTTPS, and a reverse proxy in production.

Configuration

Environment variables are injected by your shell, systemd, Docker, or process manager. .env.example lists the available variables.

Create an API key file:

cp server/api-keys.example.json server/api-keys.json

Create a plan file:

cp server/plans.example.json server/plans.json

Send the key with either header:

X-Api-Key: your-key

Authorization: Bearer your-key

REST API

Examples:

curl http://localhost:8787/health

curl -X POST http://localhost:8787/api/doc/inspect \
  -H "X-Api-Key: your-key" \
  -F "psd=@example.psd"

Read /api/catalog or /openapi.json for the full schemas. Smart objects become cached pixel layers on import. Source replacement, mesh editing, and smart-object fragment writeback are not available.

MCP

POST /mcp

Client configuration:

{
  "mcpServers": {
    "psd-editor": {
      "type": "http",
      "url": "http://localhost:8787/mcp",
      "headers": {
        "X-Api-Key": "your-key"
      }
    }
  }
}

Local stdio MCP:

node bin/psd_editor.js mcp

CLI

node bin/psd_editor.js capabilities
node bin/psd_editor.js describe setLayerProps
node bin/psd_editor.js inspect example.psd
node bin/psd_editor.js render example.psd --out preview.png
node bin/psd_editor.js batch example.psd --input ops.json --out edited.psd
node bin/psd_editor.js convert example.psd example.png

Local AI Models

Optional AI features use local ONNX / MediaPipe models. Large .onnx files are not committed by default. Download and verify them with:

npm run vendor

All inference runs locally. Images are not uploaded.

Tests

npm test

Browser tests (requires Playwright and Chromium):

npm run test:browser
