よくある質問
Does HEIC to JPG conversion lose quality?
At 90% quality the result is visually indistinguishable. Choose 100% quality if you need to preserve the original exactly.
Why can't my computer open HEIC files?
HEIC is Apple's proprietary format. Windows and Android need extra decoders, so converting to JPG avoids installing anything.
How long does batch conversion take?
Everything runs locally, so speed depends on your device. About 100 photos at 12MP typically finish in one to two minutes on a laptop.
