A: Hello!
That's no problem. If you buy one license code, you can use UPDF on 4 devices: 2 desktops (1 Windows + 1 Mac, or 2 Windows or 2 Macs) and 2 mobile devices (1 iOS +1 Android, or 2 iOS, or 2 Android). Reinstalling when you replace a new device is allowed.

Please note that there are limitations to the free version.
1.OCR can only be experienced, cannot save and copy the content.
2.The free version will add watermarks automatically when saving the file.
3.Conversion is limited up to twice a day.
4.Batch processing can only handle two files.
5.Only one template can be added on watermark, header and footer, and background separately.
6.The UPDF Cloud trial version includes 1GB of storage space with a limit of 10MB for a single file. (Upgrade to UPDF Pro to get 10GB storage space with 2GB max per file for uploading.)

Hope you have a good day!
