Private VCF Contacts to JSON Converter
Convert saved vCard 2.1, 3.0 or 4.0 contacts into structured JSON containing names, emails, phones, addresses, organizations, categories and safe photo descriptors without uploading the address book.
Ready. Your working data stays in this browser.
Files stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy.
How it works
The browser maps bounded vCard properties and parameters into an explicit schema; remote photo addresses remain inert and embedded photo bytes are described, not copied.
Practical example
Convert a phone export to JSON, compare normalized email arrays locally, and reuse the organization, category and telephone fields in a private migration script.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
