WhatsApp offers a range of options for sending files, including sending images from the gallery, HD photos, and attached documents. These options allow users to send files in their original quality and share sensitive information such as location coordinates.
The most common way to send an image via WhatsApp is through the “Attach” button, which allows users to select content from the camera or gallery. However, WhatsApp automatically compresses images when sending them, resulting in a loss of resolution. To solve this problem, WhatsApp has introduced an option to send high-quality (HD) photos and documents that retain their original resolution.
While these options prevent the platform from reducing the quality of content, they carry the risk of sharing sensitive data via image metadata. EXIF data stored in images can reveal information such as resolution, file type, date and time the photo was taken, and more. To avoid sharing this information, users can use third-party applications to modify or remove EXIF data. Additionally, users should be careful when sharing images with embedded location data.
If an image is shared in HD or as a document via WhatsApp, the EXIF data is retained. Recipients can access this information through apps like Google Files and display the coordinates of where the photo was taken posing potential privacy risks if shared with others. Therefore, it’s essential to be cautious about what information is included when sharing images via messaging platforms.
Overall, while WhatsApp provides multiple options for sending files with original quality and sensitivity concerns in mind, it’s crucial to be aware of potential privacy risks associated with sharing location data embedded in images or documents on messaging platforms.
