Transparency will be lost
GIF supports transparency, but HEIF does not. Transparent areas will be filled with a solid color (typically white). If you need transparency, consider converting to PNG or WebP instead.
Quality reduction ahead
GIF is lossless, meaning every bit of data is preserved. HEIF uses lossy compression — some data is permanently discarded to reduce file size. At high quality settings the difference is usually imperceptible, but the original data cannot be recovered.
Color depth reduction: 256-bit → 10-bit
GIF stores up to 256 bits per channel, but HEIF supports only 10 bits. You may notice banding in smooth gradients (like sky or skin tones) where subtle color transitions are lost.
What compression artifacts to expect
HEIF lossy compression can produce blurring and occasional color shifts. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.

What Happens When You Convert GIF to HEIF
Your GIF image is decoded into raw pixel data, then re-encoded as HEIF. Some quality is permanently lost during compression. CocoConvert uses high-quality defaults to minimize this.
Your GIF file is decoded — the compressed/stored pixel data is expanded into raw RGBA (with alpha channel) pixels
Transparency is resolved: transparent pixels are composited onto a white background
Pixels are re-encoded using High Efficiency Image Format's lossy compression algorithm
Metadata (EXIF, ICC profiles) is transferred where HEIF supports it
The HEIF file is saved and ready for download
