WhatsApp: Sending High-Quality Files with Ease, but be Cautious of Metadata Risks

Sending Confidential Data to Users via WhatsApp: Sharing HD Photos or Documents

WhatsApp offers several options for sending files, including sending them from the gallery, HD images, and attached documents. The latter two options allow users to send files in their original quality and share sensitive information like location coordinates.

The most common way to send an image via WhatsApp is through the ‘Attach’ button, which lets users choose content from their camera or gallery. However, WhatsApp automatically compresses images when sending them, resulting in a loss of resolution.

To address this issue, WhatsApp introduced the option to send high-quality (HD) photos and documents that preserve the original quality of images and videos while sharing them on the platform. These options are useful for sharing sensitive information without losing its quality.

While these options prevent WhatsApp from reducing image quality, they carry the risk of sharing sensitive data through image metadata. EXIF data stored in images can reveal information like resolution, file type, date and time taken, among other things. Users can use third-party applications to modify or remove this data before sharing it on WhatsApp. It’s also essential to be cautious about sharing images with embedded location data as it poses potential privacy risks if shared with others.
