Is the Animated PNG Maker free?
Yes. The Animated PNG Maker is free with no signup or watermark, and it runs in your browser with nothing to install.
How many PNG frames do I need?
You need at least two PNG frames for an animation. The maker keeps them in upload order, and you can move frames up or down before exporting the APNG.
Can the frames have different dimensions?
Yes. Each frame is rendered onto the largest uploaded canvas size, so PNG frames of different dimensions can still be combined into one animated PNG.
Does this upload my frames to a server?
No. Frame loading, timing, and APNG export all happen locally in your browser, so your PNG frames never leave your device.
Does it work on mobile?
Yes. The maker runs in any modern mobile or desktop browser, so you can build an APNG on a phone or tablet without an app.
How do I make an animated PNG?
Add your PNG frames in playback order, set a frame delay, choose whether it loops, and export. The frames are assembled into a single APNG in your browser, so nothing is uploaded and the alpha channel of every frame is preserved.
What frame delay should I use?
60 to 100 ms per frame, which is roughly 10 to 16 fps, is a good default for UI demos and loops. The minimum here is 20 ms (50 fps), but an APNG stores every frame in full, so a high frame rate costs real file size for little visible gain.
APNG or GIF: which should I use?
APNG when the animation has transparency, gradients, or soft edges, because it carries 24-bit color and a real alpha channel. GIF when the animation is flat-color and opaque, where its 256-color palette is not a limitation and the file is often smaller.
Do all browsers play APNG?
Yes. Chrome, Edge, Firefox and Safari all support it, and any browser that did not would simply show the first frame as a static PNG rather than fail.
Why does my animation jump between frames?
Almost always because the frames are not the same size. Export every frame from the same artboard at the same dimensions rather than cropping each one individually.
