オンラインで HEIC を JPG に変換する - 安全と即時

Windows does not natively support HEIC without installing the HEIF Extensions from the Microsoft Store (which costs $0.99). Converting to JPG is the free, instant solution.

Apple uses HEIC by default because it produces files roughly 50% smaller than JPG at the same quality. You can change this in Settings > Camera > Formats > Most Compatible, but then your photos take more space.

At the default 85% quality setting, the difference is imperceptible for photos. HEIC already stores lossy data, so converting to JPG at high quality preserves what you see.

Yes. Drop up to 50 HEIC files and convert them all in one batch. Great for bulk-converting a photo dump from your iPhone.

Yes. HEIC and HEIF are essentially the same format family. The converter accepts both .heic and .heif file extensions.

Yes. The quality slider goes from 50% to 100%. Default is 85% — a great balance of file size and visual quality. Use 95%+ for printing.

The conversion focuses on the image data. Some EXIF metadata like camera settings may not transfer, but the image itself is preserved at your chosen quality.

HEIC uses a more efficient compression algorithm (HEVC). The JPG format is older and less efficient, so files are typically 30-50% larger at comparable quality.

Yes. Open MiOffice in Safari on your iPhone, select photos from your camera roll, and convert them right on the device. No app needed.

No. The HEIC decoding and JPG encoding happen entirely in your browser. Your photos never leave your device.
