Need help?AVIF to HEIC Converter
AVIF and HEIC are close cousins: both wrap a still image inside an ISO HEIF container, but AVIF carries an AV1-encoded payload while HEIC carries an HEVC (H.265) one. You would convert AVIF to HEIC to drop a royalty-free AV1 image into Apple's native photo pipeline — the Photos app, AirDrop, and Live Photo workflows expect .heic, not .avif. This tool re-encodes the picture into the HEVC-based HEIC container on our servers, then returns the file.
Because both formats are lossy codecs, transcoding AVIF to HEIC is a compatibility move, not a quality gain — you re-compress an already-compressed image. Keep the Quality Preset high to minimize generation loss.

How to Convert AVIF to HEIC
- Upload Your AVIF File: Drag and drop your
.avifimage onto the page or click "Add Files". You can queue several at once and they convert with the same settings. - Set the Quality Preset: Leave "Very High (Recommended)" to keep generation loss minimal, or step down to Medium/Low when you need a smaller file. Prefer "Specific file size" if you must hit an exact byte target.
- Adjust Bit Depth or Lossless (Optional): Keep "8-bit (Recommended)" for ordinary photos; choose a higher depth only if the AVIF source carries HDR. Set "Lossless?" to Yes if you need a mathematically exact re-wrap, accepting a much larger file.
- Convert and Download: Click Convert and save your
.heicfile. No sign-up, no watermark — files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours.
Frequently Asked Questions
Does converting AVIF to HEIC reduce image quality?
It can, slightly. AVIF and HEIC are both lossy formats, so re-encoding decodes the AV1 image and re-compresses it with HEVC — a second lossy pass. At the "Very High" preset the difference is usually invisible at normal viewing sizes, but each round trip discards a little detail. In our testing, a 12-megapixel AVIF photo re-encoded to HEIC at Very High stayed within a few percent of the source file size with no visible artifacts at 100% zoom.
Why convert to HEIC instead of just keeping AVIF?
Compatibility with Apple's ecosystem. iOS and macOS Photos, AirDrop, and Live Photo features are built around .heic, and Safari is the only major browser with native HEIC display. AVIF, by contrast, is a web-first format that Chrome, Firefox, Edge, and Safari 16.4+ all render. If your destination is an iPhone or the macOS Photos library, HEIC slots in cleanly; if it is a website, AVIF is usually the better target.
Will the HEIC file be smaller than the AVIF?
Not necessarily. At equivalent quality, AV1 (AVIF) is generally a touch more efficient than HEVC (HEIC), so a like-for-like HEIC re-encode is often the same size or slightly larger, not smaller. Both are dramatically smaller than JPEG. If your goal is a smaller file rather than Apple compatibility, staying on AVIF or compressing the original is the better path.
Does HEIC preserve HDR, 10-bit color, and metadata from the AVIF?
The HEIF/HEVC container supports 8-, 10-, and 12-bit depth and HDR, so the capability is there. To carry HDR through, keep the Bit Depth at 10-bit or higher when your AVIF source is HDR; an 8-bit re-encode will flatten it to SDR. Standard EXIF-style metadata is retained where present in the source.
Is the HEVC codec inside HEIC royalty-free like AV1?
No. AVIF's AV1 codec is open and royalty-free under AOMedia, which is a major reason browsers adopted AVIF widely. HEIC relies on HEVC (H.265), which is covered by patent pools and licensing — the main reason it never gained native support outside Apple's platforms. The conversion itself is free to you; the licensing distinction is about the codecs, not our tool.
Which apps and devices can open a HEIC file?
Natively: iPhone and iPad (iOS 11+), macOS (High Sierra and later), and Safari 17+. Windows 10/11 can open HEIC with Microsoft's HEIF/HEVC extensions installed, and editors such as Adobe Lightroom and recent GIMP builds read it. If you need a file that opens anywhere without setup, convert to a universal format with AVIF to JPG instead.
Can I convert HEIC back to AVIF later?
Yes. The reverse direction is available at HEIC to AVIF, which re-encodes the HEVC image back into an AV1/AVIF container. Note that round-tripping AVIF to HEIC and back is two lossy re-encodes, so keep the original AVIF if you may need it again rather than reconstructing it from the HEIC.
