Supported file types and sizes

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 most file types to the files tool. When uploading your files, do note the following: 

• The file size limits for the files tool are:
  • Files up to 20 MB for accounts with only access to HubSpot’s free tools.
  • Files up to 2 GB for accounts with paid subscriptions. If a file is 1 GB or more, you may experience issues when uploading the file.

• Generally, it isn't recommended to host or render HTML or Javascript files in the file manager, as there may be issues when rendering the code. Instead, HTML or Javascript files should be uploaded for storage or sharing. To create a custom HTML page, learn how to build a custom template. 
  
  • 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.
  • 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
• If you're using HubSpot's free tools, you cannot upload executable files. The following file types will be blocked: 
  • sh
  • bat
  • com

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