How to convert AVIF to HEIC
Add your AVIF files
Drag the files onto the upload area or browse for them; you can add several files and they are converted one after another.
Keep HEIC as the output
HEIC is already selected. The quality slider starts at a default that suits the format (JPG 90%, WebP 80%, AVIF 60%, HEIC 80%); lower it if you want an even smaller file.
Convert and download
Press “Convert”. Each file is uploaded to our servers, converted and deleted within 5 minutes after you download the result; download the results one by one or as a ZIP.
What is preserved?
Kept
- The image resolution (pixel dimensions)
- The correct photo orientation (EXIF orientation is applied)
- Colors (adapted to sRGB)
- Transparency (alpha channel)
Changed
- HEIC is a lossy format: lower quality means a smaller file but less fine detail
Not carried over
- EXIF, location and camera data: left out of the output for privacy
- Motion: only the first frame is converted
When to use it
Open AVIF images on older Apple devices
iPhones and Macs on older system versions cannot open AVIF, but they have handled HEIC for years. Converting makes the pictures viewable there.
Keep a photo library in Apple's format
If AVIF files ended up among your photos, converting them puts the whole library into the HEIC format that the iPhone camera uses.
Limitations to know
- For animated AVIF files only the first frame is converted.
- Up to 200 MB and about 100 megapixels per file.
- The file is uploaded to our servers and deleted within 5 minutes after you download the result; several files are converted one after another.
About the formats
What is AVIF?
AVIF is a modern image format based on the AV1 video codec. It delivers very small files at high visual quality, supports transparency, HDR and animation, and is among the most efficient formats for the web. Encoding is slower than for other formats, and some older software cannot open AVIF yet.
What is HEIC?
HEIC (also called HEIF) is the photo format that iPhones and many recent cameras use by default. It stores photos in about half the space of a JPG at similar quality and supports transparency and several images in one file. Web browsers and many programs cannot open it, which is why HEIC photos are usually converted to JPG, PNG or WebP before they are shared.
Frequently asked questions
Is HEIC smaller than AVIF?
Usually not. AVIF tends to compress even better than HEIC, so the HEIC file may be somewhat larger; you convert for compatibility, not to save space.
Are both AVIF and HEIC lossy?
Yes, so converting compresses the picture a second time. Small differences can appear in fine detail, especially at low quality settings.
Does an animated AVIF stay animated?
No. Only the first frame of an animated AVIF is converted into a still HEIC image.
Is converting AVIF to HEIC free?
Yes, completely free. There is no account, subscription or watermark; just add your files and convert them.
Are my files uploaded anywhere?
Yes. This conversion runs on our servers, so your file is uploaded over an encrypted (HTTPS) connection, converted there and deleted as soon as the conversion finishes; the result is permanently deleted within 5 minutes after you download it, or 10 minutes after the conversion finishes if you never download it. Files are saved under a random code instead of their name, and processing is fully automated. EXIF and location data are not added to the output.
