BROWSER SUPPORT
Use a current, capable browser.
The editor relies on modern browser file APIs and client-side JavaScript. Updated desktop browsers provide the best experience for large contact lists.
Recommended
Use the current version of Chrome, Edge, Firefox, or Safari on a supported desktop or laptop.
Mobile devices
Small files work well on modern phones. Large VCF files and embedded photos may need more memory than a mobile browser can comfortably provide.
Before reporting a problem
Try a current browser, a smaller copy of the file, and the synthetic sample. Include the browser name and a description of the file shape, but never send private contact data.
