Great tool to get around HEIC file hassle.
Great tool to get around this strange and currently relatively obscure image file format that my iPhone uses be default. Free! And works great. Just drag a block of up to 100 files into the upload window. Click CONVERT. Then download them all in a big zip file to expand into their original files. Then I delete all the HEIC files. (Then I followed their instructions to have my phone just take JPG files to avoid this in the future.)
