BMP to HEIC Converter

About HEIC

HEIC (High Efficiency Image Container) is Apple's default photo format, introduced with iOS 11 in 2017. It is built on the HEIF (High Efficiency Image File) standard developed by the MPEG group, and uses the HEVC codec to achieve roughly twice the compression efficiency of JPEG at equal visual quality — an iPhone photo in HEIC takes up approximately half the storage of the same photo saved as a JPG, with no perceptible difference in sharpness or color.

Within the Apple ecosystem HEIC works seamlessly: iPhone, iPad, Mac, and Apple TV all open and display HEIC files natively. The problem is compatibility outside Apple devices. Windows 10 and 11 require a paid HEVC codec from the Microsoft Store to open HEIC files. Most Android phones cannot read HEIC natively. Older versions of Photoshop, Lightroom, and other image-editing programs needed updates or plugins. Web browsers had no HEIC support until very recently, and most still lack it in older versions. This means any HEIC photo you try to share via email, upload to a website, or open on a non-Apple device may simply appear as a blank icon or fail to load.

When to convert HEIC to JPG or PNG: Anytime you need to share a photo with a non-Apple user, upload it to a website or social platform, use it in software that does not support HEIC, or attach it to an email intended for a mixed-device audience. JPG is the universal image format — virtually every device, browser, app, and website on the planet opens a JPG without extra software.

When to convert to HEIC: If you are staying entirely within the Apple ecosystem and storage efficiency matters. iPhone users shooting in "High Efficiency" mode save storage; converting PNG or JPG files to HEIC preserves that advantage. HEIC also supports transparency (like PNG) and 10-bit color depth.

Converting PNG to HEIC: Less common but useful when you want HEIC's file-size advantages for images already in PNG format. Transparency is preserved in the conversion.
