About this conversion

Exports pile up: a .vcf from the old phone, one per contact shared over messenger, a backup from iCloud, a SIM card export. Drop them all here at once — a folder or a zip works too — and they are read as one list. Save it as a single .vcf for the new phone. If the same person is in several files, tick “merge duplicates” first and they come out as one card.

Just want to look inside it?

The same tool without converting anything: open the file and read it.

The same contacts, any way out

The file is read once and stays open, so the format is picked at the end: the same list can leave here as XLSX, CSV, CSV for Google Contacts, CSV for Outlook or PDF. Before that you can search it, see which people are saved twice — the same number written as (555) 201-4477 in one file and +15552014477 in another counts as one — and fold the duplicates into a single card without losing any phone, address or note.

Questions

Is this about vCard contacts, not genetic VCF files?
Yes — contacts. Variant Call Format files from bioinformatics share the extension but are a different thing entirely.
Do the files have to be the same vCard version?
No. 2.1 from Android, 3.0 from iPhone and Google, 4.0 — they are read together and written out as 3.0, which every phone and service imports.
