Convert GIF to HEIC — Upgrade Color Depth
GIF’s 256-color palette is a severe limitation that causes visible banding in photographs and gradients. Converting to HEIC upgrades the color depth to full 24-bit (16.7 million colors) with compact HEVC compression and native Apple device compatibility. The result actually looks better than the GIF source while being smaller.

Why Convert GIF to HEIC?
HEIC supports millions of colors versus GIF’s 256, eliminating the palette banding visible in photographic GIFs. HEIC files are also typically smaller than GIFs and integrate natively with Apple Photos, iCloud, and AirDrop. For still images on Apple devices, HEIC is superior to GIF in every way.
How to Convert GIF to HEIC
Upload your GIF file by dragging it into the converter or clicking to browse. Files up to 50 MB are supported.
KoalaPic extracts the first frame, expands to full color depth, and encodes as HEIC.
Download the HEIC file. Both files are deleted after 1 hour.
Quality Note
Color depth upgrades from 256 to 16.7 million colors, so the HEIC output often looks better than the GIF source. Only the first frame of animated GIFs is converted. File sizes are typically smaller than the GIF original.
