WhatsApp offers multiple ways to send files through its platform. Users can select from sending files from their gallery, HD images, and attached documents. The latter two options are useful for sharing images with sensitive information, such as location coordinates.
The most common way to send an image via WhatsApp is by clicking on the “Attach” button, which allows users to choose content from the camera or gallery. However, WhatsApp automatically compresses images when sending them, resulting in a loss of resolution. To address this issue, WhatsApp launched the option to send high-quality (HD) photos and documents that retain their original quality.
While these options prevent the platform from reducing the quality of the content, 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 the photo was taken, and more. To avoid sharing this information, users can use third-party applications to modify or remove EXIF data. Furthermore, users should be cautious about sharing images with embedded location data.
If an image is shared in HD or as a document through WhatsApp, recipients can access this information through applications like Google Files that display coordinates of where the photo was taken. This poses potential privacy risks if shared with others without proper modification of image settings on device camera before sending.
It is essential for users to be mindful of what information they include when sharing images through messaging platforms and take necessary precautions to protect their privacy while using these features effectively.
