AVIF vs HEIC
Um comparativo detalhado de AVIF Image e HEIC Image — tamanho de arquivo, qualidade, compatibilidade e qual escolher de acordo com seu fluxo de trabalho.
AVIF Image
Raster & Vector ImagesAVIF is a next-generation image format based on the AV1 video codec. It offers significantly better compression than JPEG and WebP while maintaining excellent visual quality, including HDR and wide color gamut support.
Sobre os arquivos AVIFHEIC Image
Raster & Vector ImagesHEIC is the default photo format on Apple devices since iOS 11. It offers roughly 50% better compression than JPEG at similar quality but has limited support outside the Apple ecosystem.
Sobre os arquivos HEICComparativo de vantagens
AVIF Vantagens
- Best-in-class compression efficiency — 30-50% smaller than JPEG for the same quality.
- Royalty-free and patent-unencumbered (unlike HEIC).
- Supports alpha transparency, HDR, wide gamut (BT.2020), and up to 12-bit color.
- Progressive decoding: a blurry preview appears while the file is still downloading.
- Supported in all major browsers since late 2022 — no polyfills needed.
HEIC Vantagens
- Roughly 50% smaller than JPEG at equivalent visual quality.
- 10- and 12-bit color depth supports HDR photography.
- Container format holds depth, Live Photo, bursts, and thumbnails in one file.
- Supports transparency and multi-image sequences.
- Built into iOS, macOS, and most modern Samsung and Google flagships.
Limitações
AVIF Limitações
- Encoding is CPU-expensive — an AVIF export can take 10-30× longer than JPEG.
- Older software (pre-2022) cannot open AVIF without plugins.
- Email clients still largely ignore it — stick to JPEG for attachments.
- Metadata support (EXIF, XMP) exists but tooling is less mature than for JPEG.
HEIC Limitações
- Patent-encumbered (HEVC) — Windows users must buy a $0.99 codec pack from the Microsoft Store.
- Not supported by most web browsers or older image editors.
- Sharing to non-Apple platforms usually auto-converts to JPEG, losing metadata.
- Hardware decoding required for smooth performance; software decoding is CPU-heavy.

Perguntas frequentes
AVIF (AV1 Image formatoo de arquivo) is a cutting-edge image formato derived de the AV1 video codec, backed pelo Alliance para abrir Media. It delivers up to 50% smaller arquivos than JPEG com equal ou better visual quality, plus HDR e transparência support.
HEIC (High Efficiency Image container) is the default photo formato no iPhones since iOS 11, based no HEVC video codec. It oferece roughly 50% smaller arquivos than JPEG while maintaining superior qualidade da imagem e supporting depth maps e Live Photos.
AVIF arquivos abrir in Chrome, Firefox, Safari (from macOS Ventura), Edge, e GIMP 2.10+. Support is growing rapidly, mas some older image editors may not yet handle AVIF natively.
Os arquivos HEIC abrem nativamente em dispositivos Apple, no Windows 10/11 (instalando a extensão HEIF da Microsoft Store) e em versões modernas do GIMP e Photoshop. O Google Photos também suporta visualização e conversão HEIC. Para máxima compatibilidade, converta-os para JPG com o KaijuConverter.
AVIF fornece better compressão e quality than WebP, especially para photographs. Porém, WebP has broader software support today. usar AVIF para máximo performance on moderno browsers e WebP como um reliable fallback.
HEIC is superior in quality e tamanho do arquivo mas has limited support on non-Apple plataformas. usar HEIC on Apple devices para storage efficiency. converter to JPG when compartilhando com Windows users, enviando to sites, ou printing.
