Attach a file to a message

You can attach files from your computer, mobile device, or Google Drive directly to Google Chat messages. You can send files up to 200 MB in BMP, GIF, JPEG, PNG, WBMP, and HEIC format. You can’t send certain files (details below).

  1. In Google Chat, go to the message or conversation and choose an option:
    • To attach a file from your computer, click Upload Upload.
      The file is not added to Drive. Other users get the file directly in the message.
    • To attach a Drive file, click Google Drive "".
      When you send the file, you'll be warned if the room or someone in a direct message doesn't have access. If you can edit the file, you'll see an option to grant View, Comment, or Edit access to everyone in the chat. If you grant access to everyone in a room, it also applies to people who join the room later.
  2. Select the file you want to send.
  3. Click Send "".

File types blocked in Chat

There are several reasons why you might get an upload error in Google Chat. Chat blocks files that might spread viruses, such as executable files or certain links. To keep up with harmful software, Chat regularly updates the file types that aren’t allowed.

You can’t attach certain types of files, including:

  • .ADE, .ADP, .APK, .BAT, .CAB, .CHM, .CMD, .COM, .CPL, .DLL, .DMG, .EXE, .HTA, .INS, .ISP, .JAR, .JS, .JSE, .LIB, .LNK, .MDE, .MSC, .MSI, .MSP, .MST, .NSH .PIF, .SCR, .SCT, .SHB, .SYS, .VB, .VBE, .VBS, .VXD, .WSC, .WSF, .WSH.
    This list includes any compressed form (.gz or .bz2 files) or files found in archives, such as .zip or .tgz files.
  • Documents with malicious macros.
  • Password-protected archives whose content is an archive.

If a blocked file doesn't fit any of these categories and you're sure it's safe, try uploading the file to Drive and sending it as a Drive attachment.
