Contact-card builder

What it does

Enter contact details or import a CSV and generate downloadable vCard contact files.

How to use it

1. Enter a name and optional email, phone, organization, title and HTTP URL, or import CSV with those lowercase headers.
2. Generate up to 500 contacts and download contacts.vcf plus row validation errors.
3. Processing stays in this browser. No sign-up or upload.

Example

Enter Ada Lovelace and ada@example.com to generate one vCard 3.0 contact.

Methodology

UTF-8 vCard 3.0 uses escaped text, CRLF lines and folding at 75 bytes. Invalid rows are reported separately.

Limitations

CSV up to 300,000 characters, 500 contacts and 500 characters per field. Full names occupy the given-name field; address fields, photos and deduplication are not supported.

Automation

This tool runs in your browser. No upload API or MCP endpoint is available.
