How to Convert AVIF to HEIC — Quick & Free
Fast, instant AVIF to HEIC conversion. No signup required. Just drop your .avif file and get .heic in seconds.
Batch Settings
Transparency will be lost
AVIF supports transparency, but HEIC does not. Transparent areas will be filled with a solid color (typically white). If you need transparency, consider converting to PNG or WebP instead.
Some metadata may not survive
Your AVIF file may contain ICC metadata. HEIC has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Color depth reduction: 12-bit → 10-bit
AVIF stores up to 12 bits per channel, but HEIC 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
HEIC lossy compression can produce blurring and occasional color shifts at high compression. 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.
お持ちのAVIF画像をHEIC形式へ変換しませんか？AVIFはその高圧縮率で注目されていますが、残念ながらまだ全てのデバイスやソフトウェアで広くサポートされているわけではありません。特にApple製品をご利用の場合、AVIFファイルを開けずに困った経験があるかもしれません。HEICは、Appleが採用している高効率な画像フォーマットで、AVIFに匹敵する画質を保ちながら、より多くの環境でスムーズに表示・編集が可能です。この変換ツールを使えば、大切な画像を劣化させることなく、iPhoneやMac、あるいはビジネスシーンでの共有が格段に楽になります。複雑な設定は一切不要。数クリックで、あなたの画像をより汎用性の高いHEICへと生まれ変わらせます。
- 漫画・イラスト作品の共有
- ビジネス資料での画像添付
- iPhoneでの写真管理
日本ではiPhoneユーザーが非常に多いため、AVIFで受け取った画像をHEICに変換することで、閲覧や共有の利便性が大幅に向上します。特にビジネス文書や個人的なやり取りで画像を扱う際、互換性の問題で手間取ることを避けられます。
About AVIF to HEIC Conversion
Short answer: yes, you can convert AVIF to HEIC online for free, and some quality differences may occur depending on the format types. Just upload your .avif file to CocoConvert, pick HEIC as the output, and click Convert. The whole process takes seconds.
Now for the details. AVIF is the newest image format based on AV1 video codec, delivering exceptional compression — up to 50% smaller than JPEG at the same quality. HEIC (High Efficiency Image Container) is Apple's format for iPhone photos, offering twice the compression of JPEG. Converting between these two formats lets you convert between formats quickly.
Full Name: AVIF uses AV1 Image File Format, while HEIC uses High Efficiency Image Container. Compression: AVIF uses Lossy & Lossless, while HEIC uses Lossy. Transparency: AVIF uses Yes, while HEIC uses No.
Your AVIF file is decoded and re-encoded as HEIC. AVIF supports transparency, but HEIC does not. Transparent areas will be filled with a solid color (typically white). If you need transparency, consider converting to PNG or WebP instead.
Common misconception: ""My file's transparent background will carry over to HEIC"" — in reality, heic doesn't support transparency. transparent areas become solid (usually white). save as png or webp if you need transparency.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.

What Happens When You Convert AVIF to HEIC
Your AVIF image is decoded into raw pixel data, then re-encoded as HEIC.
Your AVIF 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 Container's lossy compression algorithm
Metadata (EXIF, ICC profiles) is transferred where HEIC supports it
The HEIC file is saved and ready for download

Frequently Asked Questions
Is AVIF to HEIC conversion free?
Yes. CocoConvert offers free AVIF to HEIC conversion with generous daily limits — 25 minutes of processing time and up to 5 files per hour (250 MB each). Pro plans remove these limits.
How fast is AVIF to HEIC conversion?
Most files convert in 2–10 seconds depending on size. Large image files may take 30 seconds. Batch jobs process in parallel for maximum speed.
What happens to my files after conversion?
Your uploaded AVIF file and the converted HEIC file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.
Does converting AVIF to HEIC lose quality?
AVIF supports transparency, but HEIC does not. Transparent areas will be filled with a solid color (typically white). If you need transparency, consider converting to PNG or WebP instead.
Can I convert HEIC back to AVIF?
Yes, CocoConvert supports HEIC to AVIF conversion as well. However, if the original conversion involved lossy compression, converting back won't recover the lost data.
Versions are pinned in our worker Dockerfile and re-built via CI on every change.
