When uploading files to HubSpot, there are specific file types and size restrictions for each tool.

Please note: HubSpot does not support the management of sensitive information. For more information, please see our Terms of Service.

Files tool

You can upload any file type to the files tool.

If a HTML or JavaScript file is uploaded to the File Manager then loaded using a default HubSpot domain, it will use Content Type: text/plain. As a result, web browsers will not render the code and if a user goes directly to the file, it will display the HTML code in plain text. To avoid this, you can set these files to use one of your connected domains instead of a HubSpot default domain.

When uploading images to the files tool, the following file types are supported:

  • jpg
  • jpeg
  • png
  • tif
  • tiff
  • ico
  • bmp
  • webp

While there is no strict size limit for files uploaded to the files tool, it's recommended that you upload files below 1 GB in size. If a file is 1 GB or more, you may experience an issue with uploading the file. If you upload a video file to HubSpot, it will be transcoded to stream at 2.5 MB per second by default. For faster video streaming, ensure you are using HubSpot Video, powered by Vidyard.


The following file types can be uploaded as trackable documents in HubSpot:

  • pdf
  • pptx
  • csv
  • docx
  • xlsx

Any videos, .gifs, and hyperlinks included in your file will not function when the file is uploaded to the documents tool. The file size limit for documents is 250 MB.

Chat widget

The following file types are supported when sending an attachment to a website visitor in a chat conversation:

  • video
  • audio
  • json
  • ms-excel
  • ms-powerpoint
  • msword
  • pdf
  • gif
  • jpeg
  • jpg
  • png
  • tiff
  • calendar
  • css
  • csv
  • plain-text
  • vnd

The file size limits for the chat widget are:

  • Files up to 25 MB can be sent to a visitor in the chat widget.
  • Files up to 10 MB can be sent by the visitor in the chat widget.
