Contacts may contain private information. Keep a backup; this page does not send or persist your input. Reload or Reset clears it. Paste may normalize line endings in your browser; file input preserves decoded UTF-8 text.

BEFORE YOU IMPORT

A checkpoint.
Not a repair promise.

Make a backup of the source and destination contacts.
Review flagged blocks. A file can be well formed and still fail in an app.
Extract a small selection, then test it yourself in the destination.

No contacts are added, synced, edited or deleted. We never invent names, strip photos or rewrite version numbers.

What is checked?

Record boundaries, recognizable property syntax, VERSION count, FN for 3.0/4.0 and N for 3.0. Folded lines are read for analysis. vCard 2.1, quoted-printable and legacy charsets receive limited warnings, not full validation.

Apple’s 256 KB per-vCard limit is an advisory using a conservative 256,000-byte threshold. Photos are not decoded or validated. No email/phone validity, duplicate identity, parameter grammar or importer compatibility check.
