AVIF to HEIC Converter
Convert AVIF images to HEIC online for free. Use this exact converter when you need better compatibility, different transparency behavior, or a format that fits your next workflow better.
Converting AVIF to HEIC re-encodes the image into the HEIC container while preserving resolution and color information. The trade-off depends on the target format: lossy targets (JPG, WebP) shrink file size; lossless targets (PNG, TIFF) preserve every pixel exactly.

Switch AVIF Images to HEIC in 3 Steps
Change image format for better compatibility, smaller files, transparency support, or a more web-friendly delivery format.
Drag and drop your AVIF files or click to browse. Supports photos, screenshots, graphics, and images with transparency. Batch upload multiple files for bulk conversion.
Our engine converts your AVIF to HEIC while preserving the original resolution and DPI. Alpha transparency and embedded colour profiles (sRGB, Adobe RGB) are retained where the target format supports them.
Download your converted HEIC images individually or as a ZIP archive. Image quality is maintained at the original resolution — no downscaling or watermarks applied.
Why Convert AVIF to HEIC
HEIC is the default photo format on iPhone, iPad, and Mac. Converting to HEIC ensures your images integrate seamlessly with iCloud Photo Library, AirDrop, and all Apple applications.
HEIC uses the HEVC codec to compress photos to roughly half the size of equivalent JPG files while maintaining identical visual quality. Store twice as many photos in the same storage space.
HEIC can embed depth maps, Live Photo motion data, and auxiliary images in a single file. Portrait mode effects and computational photography features are preserved natively.
HEIC supports 10-bit color encoding, capturing over one billion color values compared to JPG's 16.7 million. Subtle gradients in skies, skin tones, and shadows render without visible banding.
Apple's Photos app stores edits to HEIC files non-destructively, preserving the original image data. You can always revert to the original without any loss of quality.

About the AVIF Format
AVIF (AV1 Image File Format) is a next-generation image format based on the open-source AV1 video codec, standardized in 2019 by the Alliance for Open Media. It delivers exceptional compression efficiency — typically 20-30% better than WebP and up to 50% better than JPEG at equivalent visual quality. AVIF supports both lossy and lossless compression, making it one of the most versatile modern image formats available.
AVIF is designed for the next era of web imagery, supporting features like HDR (High Dynamic Range), wide colour gamuts with 12-bit depth, and full transparency. Browser support has been growing steadily, with Chrome, Firefox, and Safari 16+ all providing native AVIF rendering. The primary trade-off is encoding speed — AVIF images take significantly longer to compress than JPEG or WebP, which can be a bottleneck for real-time image processing pipelines and high-volume workflows.
