HEIC uses HEVC-based compression, which packs noticeably more visual detail into a smaller file than JPG's older compression scheme — typically around 40 to 50 percent smaller at comparable quality. It's the default photo format on recent iPhones and some Android devices for exactly this reason, since it lets phones store more photos in the same storage space. HEIC can also store multiple images in a single file, such as Live Photos, and supports 10-bit color depth, which JPG's 8-bit color cannot match.
Converting JPG to HEIC makes sense if you're archiving a large photo library and want to reclaim storage space, or if you're preparing images for an Apple ecosystem workflow that expects HEIC. The main consideration is compatibility: while modern Windows, macOS, and recent software generally handle HEIC fine, some older programs and platforms still expect JPG specifically.

- Significant storage savings for large photo archives
- Multi-core processing for fast handling of large batches
- Option to delete original JPG files automatically once converted
- No recurring subscription or hidden upload limits
How much smaller will my photos be after converting to HEIC?
Typically around 40 to 50 percent smaller than the equivalent JPG at similar visual quality, since HEIC uses more efficient HEVC-based compression.
Will HEIC files open on older software?
Most current operating systems and recent software handle HEIC without issue, but some older programs or platforms may still expect JPG specifically, so it's worth checking compatibility with your intended use case.
Does converting to HEIC reduce image quality?
Some quality is traded for smaller file size since HEIC also uses lossy compression, though at a higher quality setting the visible difference is typically minimal.
