About formats

AVIF

AVIF (AV1 Image File Format) is a modern, royalty-free image format based on the AV1 video codec. It delivers dramatically better compression than JPEG and PNG — often halving file sizes — while supporting high dynamic range (HDR), 10+ bit color, and alpha transparency. AVIF is supported by Chrome, Firefox, and Android.

Developer: Alliance for Open Media
Initial release: 2019
Compression: Lossy or lossless
Color depth: up to 12-bit HDR
Transparency: Yes

HEIC

HEIC (High Efficiency Image Container) is Apple's implementation of the HEIF standard, using the HEVC codec. It stores images at roughly half the file size of JPEG at comparable quality. HEIC is the default photo format on iOS 11+ and macOS High Sierra+, and supports multiple images and depth data within a single file.

Developer: Apple / MPEG
Initial release: 2017
Compression: Lossy
Color depth: up to 16-bit HDR
Transparency: Yes
Animation: Yes

Best for

Saving iPhone photos
High-quality mobile photography
Reducing photo storage on iOS
HDR image capture
Efficient photo archival on Apple devices

Pros

+Roughly half the size of JPEG at comparable quality
+Supports transparency and animation
+Stores multiple images and depth data
+Default iOS photo format

Cons

−Limited support on older Windows and non-Apple platforms
−Requires newer software to decode
−Less universally supported than JPG
−No universal web browser support historically

Frequently Asked Questions

Is converting AVIF to HEIC free?

Yes. This AVIF → HEIC converter runs entirely in your browser and is completely free — no account, no credits, no watermark.

Which devices and platforms can I use to convert AVIF to HEIC?

Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.

Are my AVIF files uploaded to a server?

No. Files never leave your device. The entire AVIF → HEIC conversion runs locally in your browser, so your data stays private.

Can I convert multiple AVIF files at once?

Yes — batch conversion is supported. Add as many AVIF files as you like and convert them to HEIC in one pass, then download the results together.

What is the maximum file size?

There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.

Will converting AVIF to HEIC reduce the quality?

Because both formats use lossy compression, the HEIC output will not bring back any quality that has already been lost in your AVIF file. Avoid repeated re-encoding to keep the best quality.

Will transparency be preserved when converting AVIF to HEIC?

Yes. Both AVIF and HEIC support alpha-channel transparency, so transparent areas of your file are kept unchanged in the HEIC output.

How will the file size change after converting AVIF to HEIC?

Both formats use comparable compression, so the HEIC output will be similar in size to your AVIF file — typically within 10–20% of each other.
