HEIF to APNG Converter
Processing entirely on your device — large files may take a moment.
Convert an animated GIF to APNG to keep smooth color and clean transparency while staying animated. If your files are still in HEIF format, this page is the shortcut: HEIF is the family container HEIC belongs to — same HEVC-based compression, often used by name on Android and camera firmware where HEIC is the Apple branding.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the HEIF format
HEIC (High Efficiency Image Container) is the HEIF container carrying HEVC-compressed image data, and it has been the default photo format on iPhones since iOS 11. At equivalent quality it stores photos in roughly half the space of JPG, keeps 10-bit color and HDR information intact, and can hold multiple images — bursts,Live Photos pairs, even depth maps — in one file.
Its weakness is everything outside Apple's ecosystem. Windows needs an extension from the Store to preview it natively, many web services still reject the upload, and HEVC's patent licensing slowed hardware adoption on non-Apple devices. Android 9+ phones generally handle it, but the desktop web remained JPG territory for years.
+Strengths
- ✓About half the size of JPG at the same quality
- ✓10-bit color and HDR survive the pipeline
- ✓One file can hold bursts, sequences and depth data
!Limitations
- −Windows and many web services need extras to open it
- −HEVC patent licensing complicated adoption outside Apple
- −Thumbnail and preview performance on old hardware is poor
About the APNG format
APNG (Animated PNG) is what GIF should have been: the same PNG file format with an animation extension — every frame in full 24-bit color with 8-bit alpha, no 256-color palette, no binary transparency with jagged edges. All modern browsers render it natively.
GIF has one job APNG does better in every dimension: color fidelity and clean transparency for animation. Converting an animated GIF to APNG keeps every frame but upgrades color depth and kills the halo around transparent edges. The only cost is file size — true color costs bytes.
+Strengths
- ✓Full 24-bit color per frame (no 256-color palette)
- ✓8-bit alpha transparency — no jagged edges
- ✓Native rendering in every modern browser
!Limitations
- −Larger files than GIF for the same animation
- −Legacy tools may show only the first frame
- −Not accepted by some social platforms
Why convert HEIF to APNG?
Converting makes sense where the strengths of APNG meet what HEIF cannot give you. Full 24-bit color per frame (no 256-color palette) Meanwhile Windows and many web services need extras to open it One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this HEIF to APNG converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will I lose quality converting HEIF to APNG?
No — APNG is a lossless format, so every pixel of the converted image matches your original HEIF file. You can also adjust the quality/size balance before converting when the target format supports compression.
Can I convert several HEIF files at once?
Yes — drop as many files as you like into the tool and they are converted in one batch. When more than one file comes out, everything is bundled into a ZIP for a single download.
What happens to EXIF data and other metadata?
Conversions here re-encode the image, and re-encoding generally does not carry the original metadata over. If the EXIF data of your HEIF files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
