Why a file you received was refused

For security, WYP.chat checks every file it receives before keeping it. A refused file shows “File rejected by the security check”, its name and the reason.

The reasons

1. Apps and programs are blocked: installable or executable files (.apk, .exe, .dmg, .msi, .jar…). They can contain a virus and are never kept.
2. Type not accepted: only images, videos, audio, PDF, text and Office documents get through. On WhatsApp, photos must be JPEG, PNG or WebP.
3. File too large: on WhatsApp, 5 MB for an image, 16 MB for a video or audio file, 100 MB for a document.
4. File altered in transit or content does not match its declared type: ask the customer to send the file again, or in another format (PDF, photo).
