Short answer

Signal normally re-encodes videos you send as media, which removes most metadata for recipients. If you send a video as a file/document, Signal may preserve the original metadata. Strip it first if you want maximum privacy.

What Signal removes for normal video sends

In standard chats, Signal compresses videos to protect privacy and reduce size. That usually drops GPS/location tags and many EXIF‑like atoms in MP4 files.

When metadata might remain

  • Sending as a file/document (often keeps the original file intact).
  • MOV or other formats that Signal may not re-encode fully.

How to share videos safely on Signal

  1. Export/convert your video to MP4 if it’s MOV.
  2. Strip metadata locally.
  3. Send the cleaned MP4 in Signal.
