// ABOUT HEIC
HEIC (High Efficiency Image Container) is Apple's default camera format on iPhone and iPad since iOS 11. It uses the HEVC video codec to achieve roughly 50% better compression than JPEG at equivalent quality. HEIC supports transparency, depth maps, and burst sequences. However, HEIC encoding requires a commercial HEVC licence, so this tool supports HEIC as an input-only format.
// ABOUT GIF
GIF is a legacy format dating to 1987 that supports animation and simple binary transparency. It is limited to a palette of 256 colours per frame, which means photographic content will undergo colour quantisation. Despite its age, GIF remains ubiquitous for short animations and reaction images across messaging platforms and social media.
// WHY CONVERT
Converting HEIC to GIF is useful when you need your image in a format suited for short animations, reaction images, simple graphics with few colours, and legacy web content. Note that converting from a lossy source (HEIC) to a lossless target (GIF) preserves the existing quality but cannot recover detail already lost during the original compression. Image Toolz runs the entire conversion directly in your browser. Nothing is uploaded to any server — your files remain completely private on your device. The tool handles images up to 200 MB and most conversions complete in under a second.
// FAQ
What is HEIC?
HEIC is Apple's default photo format on iPhone and iPad, using HEVC compression.
What is GIF?
GIF is a legacy format limited to 256 colours, commonly used for simple animations.
Will converting HEIC to GIF lose quality?
Yes, significantly for photographic content. GIF's 256-colour palette causes colour reduction and banding in photos.
Is it safe to convert my files here?
Yes. All conversion runs entirely in your browser. Your images are never uploaded to any server and nothing leaves your device.
