What a .vcf file is

A .vcf (vCard) is a text file of contact cards, one after another between BEGIN:VCARD and END:VCARD. Phones, Gmail, iCloud and Outlook all export contacts this way, which is why the file turns up when someone shares a contact, backs up a phone or leaves a job.

Opening one is harder than it should be. Windows hands it to the Contacts app, which shows only the first card; Excel shows raw lines; a vCard 2.1 from an Android phone shows names as =D0=9C=D0=B0… Here all three versions of vCard are read the way they were meant to be, including the long names that Samsung phones break across lines in the middle of a letter.

What you can do here

Read anythingvCard 2.1, 3.0 and 4.0, Google and Outlook CSV, your own Excel list, and the contacts inside an Outlook .pst.
Fold duplicatesCards that share a phone number or an email are one person. Merging keeps every field and remembers the other names.
Leave in the right shapeCSV with the exact columns Google or Outlook imports, a vCard for phones, or a readable Excel table.

Questions

My file has hundreds of contacts — are they all shown?
Yes, every card in the file, a hundred per page, with a search box that matches names, companies and any part of a phone number.
Can I open several .vcf files at once?
Yes — select them all, or drop a folder or a zip. People who appear in more than one file are flagged, and “merge duplicates” folds them together.
Is the file uploaded?
No. It is read by this page on your own device; there is no server for it to go to.
