I have a single VCF file with 500+ contacts exported from various sources (Outlook, iCloud, Android). Many contacts include non-English names, profile pictures, and full address info. Most free online splitters don’t preserve images or Unicode details, and they lag or fail for big files. Is there any trusted offline tool to split vCard 2.1/3.0/4.0 files into individual VCFs while retaining ALL fields like photos, special characters, multiple phone numbers, etc.? What issues should I watch out for, and what makes a paid tool genuinely better?
