Many times when a client gives you a pickup, you will get this “HEIC” or any other format, it is not open in Photoshop or Illustrator, after saying a few times and the client gives the same file (many give JPEG), again many clients do not understand, and many clients again and again. After saying that and leaving with this file (maybe many are biz), the designer may then hesitate to go or not (who doesn’t know), if that is not the problem.
Format the file that the client is giving the file, search by typing “HEIC to JPEG”, you will find many websites, then you can easily convert from JPEG to whatever format you want to convert, Just --------
Format (whatever format) to jPEG / PNG
Something else is going on -----
Many times when a client gives a text file, it comes in some form other than doc / word / notepad format, so if that is how you can convert online.
Format (in the same format) to doc / word
Many times the client gives logos in PDF format, you can convert these to JPEG / PNG format if you wish.
Again many PDF text files you want
The same way you can convert to doc / word
So much more you can convert online, you just have to search
