A family of Microsoft relational database management systems designed for ease of use.
Short answer. No. There is no way to make it "web-enabled" and no free way to migrate it to a web-browser based application.
Access is a Windows application that requires the Windows operating system to run. Therefore, it can only run on a desktop or laptop computer running a version of Windows.
There ARE ways to make the DATA available remotely. All require some investment. Most require replacing or supplementing the interface (forms, etc,) with interface elements pertinent to those environments.
One way is to use a Remote Desktop application to connect to your computer from a remote location via a laptop that can connect to your workplace via the internet. In your situation, where it sounds like you are the only user, that's probably the most cost-effective method. It won't work on a smart device, of course, but a tablet running Windows should support it.
Another option would be to migrate the data to SharePoint or SQL Azure, which are "cloud" locations so that you can connect to the same data from your desktop or laptop running Windows with the Access accdb interface on it.
The least feasible option--in this circumstance, at least--would be to replace Access with a web-browser based interface and a SQL Azure or hosted SQL Server database. That requires a whole different set of development skills in the relevant development format, e.g. Net.
Still another option would be to migrate the data to SharePoint or SQL Azure and create a PowerApps application in MS 365 to do only the essential functions you need to do remotely, such as entering a new sale while in the customer's office. The heavy computing portion of the functionality is still done on the desktop via the Access interface.
