Why convert
HEIC — the iPhone photo format that Windows and many sites refuse. So an iPhone photo opens on Windows and uploads to sites that don't understand HEIC. TIFF — a print and scan format: lossless but very heavy.
What changes in the file
Quality will not improve, and the file gets noticeably bigger. EXIF data and location are removed by default.
Which settings to pick
For websites and email, scale to 1920 on the longest side.
