API Trim

APITrim helps developers quickly reduce large Swagger / OpenAPI specifications.

Instead of working with huge API files, you can keep only the endpoints you need and download a clean, smaller JSON specification.

How it works:
1. Add your Swagger JSON
Paste your copied Swagger/OpenAPI JSON or drag and drop the file into the extension.

2. Select endpoints
Browse endpoint groups and choose the specific endpoints you want to keep.

3. Download the trimmed spec
Download a new JSON file containing only the selected endpoints.

Key features:
• Paste Swagger/OpenAPI JSON directly
• Drag and drop JSON files
• Select endpoint groups or individual endpoints
• Generate a smaller, clean API specification
• Works entirely in your browser
• No data is sent to external servers

Use cases:
• Creating smaller API specs for frontend teams
• Sharing only specific endpoints with partners
• Simplifying large OpenAPI documentation
• Extracting endpoints for testing or SDK generation
