Why convert ZCF to WebP?
ZCF is the contact backup file created by the Truecaller app, holding names, phone numbers and email addresses. The image shows each contact under their name as a heading, with their phone number and email address listed beneath.
WebP stores the rendered image in a modern, efficient format, so the file is noticeably smaller than an equivalent PNG or JPG.
Frequently Asked Questions
How do I convert ZCF to WebP?
Drop your ZCF file above and press Convert. Our servers read the contacts from the backup, lay them out one by one and render the pages. The result is saved as a compact WebP image, ready to download.
Which Truecaller details from the ZCF backup reach the WebP?
For each contact the converter reads the name, phone number and email address. The number and email are shown under the contact's name, or under the number itself when a contact has no name.
Is a ZCF file that already holds vCard data converted to WebP?
Yes. When the backup already contains vCard entries, they are read directly and laid out as contacts in the same way.
What happens when a ZCF file fills several WebP pages?
Each page is rendered at 144 dpi and saved as its own WebP image, named page-1, page-2 and so on, and they download together as one ZIP. A single page downloads as one WebP file.
How much smaller is the WebP from a ZCF file?
WebP typically produces files around a quarter to a third smaller than JPG at similar visual quality, and far smaller than PNG, while text and lines stay clear.
Is my .zcf file kept private?
Your file is uploaded over an encrypted connection, converted on our servers and deleted automatically within 24 hours. We never read, share or keep your files, and no account is needed.
