Need help?Convert HEVC to APNG Online
Turn an HEVC (H.265) clip into an animated PNG that keeps full 24-bit color and smooth 8-bit alpha transparency — something a GIF cannot do. APNG is the right target when you want a short, looping animation with soft anti-aliased edges (stickers, UI micro-animations, logo loops) rather than the banded, hard-edged look GIF produces. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark.
How to Convert HEVC to APNG
- Upload Your HEVC File: Drag and drop your
.hevcclip onto the page or click "Add Files" to pick it from your device. - Set the Framerate: Leave Framerate on the default 10 FPS for a balanced animation, or raise it for smoother motion — every extra frame is stored losslessly, so higher FPS means a noticeably bigger APNG.
- Adjust Image Quality, Resolution, and Colors (Optional): Lower Image quality (%) or cap the resolution under Image resolution to shrink the file; keep Colors on "ORIGINAL" for full color, or switch to "By Color Reduction + Dither" to trim the palette.
- Convert and Download: Click Convert and save your animated PNG. No sign-up, no watermark.

Frequently Asked Questions
Why is my APNG file larger than the original HEVC?
HEVC (H.265) is a highly efficient inter-frame video codec — it stores only what changes between frames. APNG stores each frame as a near-lossless PNG, so a few seconds of motion can balloon in size. Keep the clip short, lower the Framerate, and cap the resolution to keep the APNG manageable. If size matters more than transparency, convert HEVC to GIF or keep it as video instead.
Will an APNG play in every browser?
APNG animates in Chrome 59+, Firefox 3+, Safari 8+, Edge 79+, and Opera 46+ — about 94.7% of global traffic per caniuse. The key safety net: any viewer that does not understand APNG (Internet Explorer, very old Edge) simply shows the first frame as a static PNG, so it never displays a broken image.
Does converting HEVC to APNG keep transparency?
Standard HEVC video has no alpha channel, so there is usually no transparency to carry over — the APNG will be fully opaque. APNG's 8-bit alpha matters when your source already has transparency or when you later edit the frames; it is what lets APNG show soft, anti-aliased edges that GIF cannot.
How do I make the APNG smaller without it looking terrible?
In our testing, a 3-second 720p HEVC clip at the default 10 FPS produced an APNG several times larger than the source. The three levers that help most, in order: shorten the clip, lower the Framerate, then cap resolution under Image resolution. Reducing Colors with dither helps for flat graphics but adds visible noise on photographic content. You can also run the result through compress APNG afterward.
What framerate should I pick?
The 10 FPS default is a deliberate balance — smooth enough for UI loops and stickers, small enough to stay shareable. Bump it to 20-30 FPS only for fast motion where the lower rate looks choppy, and accept the larger file. Frame count, not just FPS, drives size: a longer clip at any rate means more stored PNG frames.
