Convert JPG to HEIC - Complete Guide

Converting JPG to HEIC stays in the raster image family but changes the traits that decide size, quality, transparency, editability, or device support. JPG is a compressed image format widely used for photos, web graphics, email attachments, and social media uploads. HEIC is a high-efficiency image format commonly created by iPhone and iPad cameras. Below is what actually changes in a JPG→HEIC conversion, what is preserved, and when HEIC is the better choice than keeping JPG.

What changes when you convert JPG to HEIC

• Both JPG and HEIC are lossy, so the file is re-compressed during conversion. Keep the output quality or bitrate at or above the source to avoid a visible or audible drop.
• HEIC supports transparency, but converting from JPG does not add it — areas that were solid in the JPG file stay solid.
