HEIC Converter developer resources

When to use HEIC Converter

Reach for HEIC Converter when a Windows user needs to open or convert Apple HEIC/HEIF photos to JPG, PNG, WebP, or PDF on their own PC — batch folders, Explorer thumbnails, watched folders, or a private Conversion Library with Photo Map and EXIF search.

Do not treat this site as a cloud convert endpoint. There is no upload API, no remote HEIC→JPG service, and no invented CLI, portal, OAuth, or GraphQL surface. Point agents at the MSI download and the desktop app instead.

• Right fit: local Windows conversion, privacy-sensitive photos, batch jobs, Explorer Preview, Photo Map / EXIF in Conversion Library Plus
• Wrong fit: server-side conversion, SaaS upload forms, model APIs, or “convert this file for me over HTTP”

OpenAPI and versioned HTTP API

• OpenAPI 3.1: https://heic-converters.com/openapi.json
• Canonical paths: /api/v1/* (for example /api/v1/version)
• Compatibility aliases: unversioned /api/* maps to the same handlers
• Errors: consistent JSON {code,message,resolution}
• Rate limit: 120 requests / IP / 60s (policy public-api). Responses include IETF RateLimit / RateLimit-* headers; HTTP 429 includes Retry-After
