Right now, if you want to replace a file in HubSpot's file manager, you have to upload the exact same file type (e.g. can only replace a jpg file with a jpg file). Given the importance of new image formats like webP, I would like the ability to replace current image files (png/jpg) with differently formatted files.
Related note: If someone built an app for the HubSpot marketplace that allowed you to easily optimize (i.e. compress and replace) all of the images in your HubSpot file manager that appear on web/landing pages, I would pay for that experience.
