vCard Contact File Generator
Build a properly formatted .vcf contact file (vCard 3.0 or 4.0) that phones, address books, and email clients accept on first import. Fill in the fields, watch the raw vCard update live, then download the file or copy the text. Everything runs in your browser — no contact data leaves the page.
如何使用
- 选择 vCard version — 3.0 has the widest reader support, 4.0 supports modern fields.
- Enter the name, organization, phones, emails, address, website, birthday, photo URL, and note as needed. Only first or last name is required.
- If you supply a photo URL, choose whether to link it (smaller file, image stays remote) or embed it (base64 inside the .vcf, works offline).
- 点击 download icon to save the .vcf file, or the copy icon to put the raw vCard text on your clipboard.
- Import the .vcf into iOS Contacts, Google Contacts, Outlook, Apple Address Book, or any other vCard-compatible app.

常问问题
-
What is a vCard and what is a .vcf file?
A vCard is the standard data format for exchanging electronic business cards. It is a plain-text record that lists a contact's name, phone numbers, email addresses, postal address, organization, and other details using property tags like FN, TEL, EMAIL, and ORG. The file is saved with a .vcf extension and is recognized by virtually every contact manager, email client, and mobile address book.

What is the difference between vCard 3.0 and 4.0?
vCard 3.0 (RFC 2426) was published in 1998 and is the version most readers — including Outlook, iOS, and Android — still understand best. vCard 4.0 (RFC 6350) added cleaner TYPE syntax, full Unicode support without quoted-printable encoding, ISO 8601 dates, and new properties like GENDER and KIND. Use 3.0 when you need the broadest compatibility and 4.0 when you control the importer or need modern fields.
-
Why do vCard files use 75-character line folding?
RFC 6350 §3.2 requires that no line in a vCard exceed 75 octets so the file stays compatible with mail transport systems that historically limited line length. Lines longer than 75 octets are broken with CRLF and continued on the next line with a single leading space. Skipping this step is the most common reason a hand-written vCard fails to import — readers see a malformed property and stop parsing.
-
How does an embedded photo get into the .vcf file?
vCard supports two ways to attach a photo. The PHOTO;VALUE=URI form stores only a URL — the contact app fetches the image on demand. The PHOTO;ENCODING=b;TYPE=JPEG form (3.0) or data: URI form (4.0) stores the image bytes directly as base64 inside the file, which keeps the photo available even when the original URL goes away but makes the .vcf much larger. To embed a remote image, the generator must be able to read its pixels, which requires the image host to send CORS headers permitting cross-origin canvas access.
