An iPhone photo bound for an old Windows program that cannot decode HEIC has to become BMP, the format that program does understand. HEIC is the photo format iPhones use by default, efficient on the phone but unreadable in many desktop tools and browsers. This free heic to bmp converter does that conversion entirely in your browser, so your file is never uploaded and no signup is needed. BMP output is an uncompressed 24-bit bitmap, which any legacy tool can open, at the cost of a much larger file than the input. The honest limits: BMP has no transparency in this 24-bit output, so see-through areas become white. The file will also be much larger than the input.
How to use this heic to bmp converter
