What is a .vcf (vCard) file?

A .vcf is a vCard contact file used by many apps (Apple Contacts, Outlook, Google Contacts) to store and share contact information.

How do I validate and download a fixed file?

Open /validate, upload your .vcf, review results, then use “Download fixed file” if it appears. Some issues cannot be auto-fixed.

Why won’t my contacts import?

Most import failures are due to missing or invalid required fields (e.g., VERSION, FN, N) or invalid encodings. Fix the first error shown or use the fixed download.

Getting Started

Tip For a quick fix, go straight to /validate and upload your file.

What is a .vcf? It’s a vCard contact file that stores one or more contacts. Most contacts apps (Apple, Google, Outlook) can import it.
Validate & fix a file: Go to /validate, upload your .vcf, review the results, and click Download fixed file if offered.
Is it safe? Files are processed in memory; results are not stored. See “Limits & Privacy” below.

How‑Tos

Export from Apple Contacts: Select contacts → File → Export → Export vCard….
Export from Google Contacts: Left sidebar → Export → choose vCard (for iOS Contacts).
Export from Outlook: People → select contacts → Export → choose vCard (.vcf).
Merge multiple .vcf: Zip them and use the Bulk tab (when available) or concatenate them in a text editor.
Inspect contacts: Open the file in a text editor; each BEGIN:VCARD…END:VCARD block is one contact.

Troubleshooting

VERSION missing

Every vCard needs a VERSION (e.g., VERSION:4.0). The fixed file may add a safe default.

FN/N issues

FN is the display name; N is the structured name. Missing or malformed values are common import failures.

TEL/EMAIL normalization

Phone numbers and emails are normalized to consistent, standards‑friendly formats where safe.

Encoding and line folding

Quoted‑printable and long line folding must be valid; we flag and repair common issues.

Limits & Privacy

Privacy first Files are processed in memory; we do not store your contacts.

Retention: We do not persist your uploaded contacts. Logs store minimal request metadata (request ID, status) for operations and abuse prevention.
Encryption: Data is encrypted in transit (HTTPS). At rest, only minimal logs live in provider systems.
Size limits: Typical files up to a few MiB work. Very large files may be refused for safety.
