- For
- Japanese My Number card applicants with iPhone photos
- Worth noticing
- It handles one HEIC/HEIF image up to 30 MB and says it preserves the original resolution by default without copying source EXIF metadata.
Field notes
The page distinguishes file-format checks from the photo’s content rules: it lists JPEG, RGB, 20 KB–7 MB, and 480–6,000 pixels, while directing applicants to official guidance for framing and other image requirements. It says conversion happens locally in the browser and that source EXIF data is not copied, though information visible within the image remains. The converter handles one file at a time, up to 30 MB; large files may exceed a device’s processing capacity.
