ICO to HEIC

Convert ICO to HEIC

Upload a ICO file and download HEIC. Typical use: compact photos used on many Apple devices.

How it works

Drop one ICO file (up to 10 MB), start conversion, and download the result. The file is processed on the server.

Security and privacy

  • Encryption at rest

    Files are encrypted during storage with AES-256-GCM using a unique key per file

  • Auto-deletion

    Uploaded and processed files are removed after the session ends

  • Temporary sessions

    Processing sessions expire automatically and are not kept as a permanent archive

  • Protected download links

    Downloads require a short-lived access token — not a public permanent URL
