Convert HEIF to APNG Online

Make an Animated APNG from HEIF Photos

Drop in one or more HEIF images and this tool stitches them into a single animated APNG — each photo becomes a frame, played in upload order. It's the fix for HEIF's biggest problem: HEIF is an Apple-first format that most browsers, Windows apps, and websites can't open, while APNG (Animated PNG) plays in about 94.7% of browsers worldwide and falls back to a clean static image everywhere else. Upload a single HEIF and you get a one-frame APNG; upload a HEIF image sequence (the animated msf1 variant) and its frames are unpacked into the animation.

How to Convert HEIF to APNG

1. Upload Your HEIF Files: Drag and drop or click "Add Files" to select your .heif images. Add several at once and they'll become frames in one APNG, in the order you upload them; a single file produces a one-frame APNG.
2. Set the Framerate: Use the FRAMERATE control to choose how fast frames advance — 10 FPS is the recommended default. A lower framerate holds each photo on screen longer (good for a slideshow); a higher one makes motion smoother.
3. Choose Colors, Quality, and Resolution: Leave Colors on "Original" for full true-color output, or pick "By Color Reduction + Dither" to shrink the file. Adjust Image quality (%) and set a preset or custom resolution to control the final size.
4. Convert and Download: Click Convert and download your APNG. Files upload over an encrypted connection, are processed on our servers, and are deleted automatically after a few hours — no sign-up, no watermark.

HEIF vs APNG — Why Convert

Frequently Asked Questions

Can I combine several HEIF photos into one animation?

Yes — that's the main use of this tool. Upload multiple HEIF images and each one becomes a frame in a single animated APNG, played in the order you added them. Set the FRAMERATE to control how long each frame stays on screen: 10 FPS advances quickly for smooth motion, while 1–2 FPS gives a slideshow pace where each photo lingers. If you upload just one HEIF, you get a valid single-frame APNG, which is simply a static PNG that any viewer can open.

Why convert HEIF to APNG instead of keeping HEIF?

Compatibility. HEIF was built around Apple's ecosystem and the HEVC codec, and no major desktop browser renders a .heif file natively — on Windows you need the paid HEVC Video Extensions from the Microsoft Store just to preview one. APNG plays in roughly 94.7% of browsers (Chrome 59+, Firefox 3+, Safari 8+, Edge 79+, Opera 46+) and in any standard image viewer, with no plug-ins. Converting trades HEIF's smaller file size for an animation that actually opens for the people you send it to.

Will my APNG lose quality or balloon in size compared to the HEIF?

APNG is lossless, so the conversion adds no artifacts when you keep Colors on "Original" and Image quality at 100% — on screen the output looks identical to the source. The catch is size: HEIF is one of the most space-efficient formats made, using HEVC to pack a photo into a fraction of a JPEG's size, while APNG stores every frame in full 24-bit color losslessly. A multi-photo animation can run several times larger than the source HEIF files combined. To shrink it, switch Colors to "By Color Reduction + Dither," lower the Image quality (%), reduce the resolution preset, or run the result through compress APNG afterward.

What if I just want a single static image, not an animation?

Then pick a still-image target instead. A one-frame APNG works, but if you only need a normal openable photo, convert to PNG with HEIF to PNG for lossless quality, or use the HEIF converter to choose any output format. APNG is the right choice specifically when you want motion — turning a burst of photos or a HEIF image sequence into a single looping animation.

Is converting HEIF to APNG private?

Yes. Your HEIF files are uploaded over an encrypted (TLS) connection, converted on our servers, and the uploads are deleted automatically after a few hours. There's no sign-up, no watermark on the output, and files are never shared or made public. In our testing, a set of four 12-megapixel HEIF photos combined into a 10 FPS APNG at default quality finished in a few seconds; the only practical limit on a large batch is upload size and time, not your device.
