Hi Product Hunt, I built VCF Duplicate Remover after seeing how easily contact backups accumulate repeated entries when contacts are exported, restored, transferred between phones, or combined from multiple address books. Because contact files contain sensitive personal information, I wanted the tool to work locally in the browser. Your VCF data is not uploaded for processing. The tool can: • Remove duplicate contacts from one or multiple VCF files • Match contacts by normalized phone number, email, UID, name plus contact details, or exact vCard content • Support vCard 2.1, 3.0, and 4.0 files • Show duplicate groups before anything is removed • Let you choose which contact stays • Prefer the most complete version automatically • Preserve the selected contact’s original vCard fields • Download a clean VCF without overwriting the original file It is completely free and requires no account. I would genuinely appreciate feedback on the matching options, review workflow, and any unusual VCF files that the tool should handle better. Thank you for checking it out.
