HEIC is the default photo format on iPhones since iOS 11, but many platforms and applications require JPEG. Converting HEIC to JPEG makes your iPhone photos universally compatible.
HEIC files are approximately 50% smaller than JPEG at equivalent quality, which is why Apple chose this format. However, the compatibility limitations mean you often need to convert to JPEG for sharing, editing, and uploading.
With ImgTools, upload your HEIC file and it will be converted to JPEG automatically. You can adjust the quality slider to control the output file size. For archival quality, use 90-95%. For web sharing, 80-85% is sufficient.
Browser support for HEIC varies. Safari on Mac handles HEIC natively. Chrome and Firefox require your operating system to support HEIC decoding. If your browser cannot read the HEIC file, you may need to use your iPhone's share function to convert it before uploading.
All conversion happens locally in your browser for complete privacy.
