Animated PNG maker.

An animated PNG, or APNG, is a PNG file that holds more than one frame. It plays like a GIF, but it keeps full colour and real transparency, where a GIF is limited to 256 colours and a pixel that is either clear or solid. This APNG maker turns several pictures, or a GIF, into one animated PNG in your browser. You set the order, the time of each frame, how many times it plays and the width, and nothing is uploaded.

How to make an animated PNG

1. Drop PNG, JPG or WebP pictures on the box, or a GIF, or click to choose them. You can pick several at once. A GIF is split into its frames, each with its own time.
2. Drag the frames into order. On a phone, hold a frame first. Sort by name and Reverse order do it in one click, and Add pictures adds more.
3. Set Seconds per frame for all frames. To give one frame its own time, type it in the small box under that frame.
4. Choose Plays: Forever, Once, or a number of times. Set Width (px).
5. Pick Colours. Automatic keeps every colour and uses a smaller indexed file when the frames have 256 colours or fewer. Full colour always keeps every colour. 256 colours gives a smaller file for photos, with some colours merged.
6. Under More settings, choose the shape, how frames of another shape fit, the background (See-through is the default), a fade between frames and the playback direction.
7. Click Download the animated PNG. The file is made again a moment after every change, and its size is shown first.

Where an animated PNG plays

MDN lists support for APNG in Chrome from version 59, Edge from 12, Firefox from 3, Opera from 46 and Safari from 8 (checked 19 Oct 2026, MDN image types). MDN also says it suits simple animations that do not need to match a sound track. A program that does not know APNG still opens the file as a normal PNG and shows the first frame, because the PNG specification keeps the first frame as the standard image (checked 19 Oct 2026, W3C PNG, third edition). So the file is safe to share: where the animation is not supported, it falls back to one picture. For a given app or website, check its own help page for what it accepts, since uploads are often converted.

How the file is made

The first frame is stored whole. Each later frame stores only the box around the pixels that changed from the frame before, drawn on top of it, so a mostly still animation stays small. A frame that is exactly the same as the one before is not stored again: its time is added to the earlier frame, and the summary tells you when that happened. The delay of each frame is written in thousandths of a second, so you are not limited to multiples of 0.01 s as a GIF is. The play count is written into the file, and 0 means it plays forever, as the PNG specification says.

Colours and file size

The summary above the download names what was written, such as "256 colours or fewer, nothing lost" or "256 colours, some colours merged", so you always know whether the pixels are exact. Width has the most effect on size: halving the width leaves a quarter of the pixels.

Time and length

The length is the number of frames times the time per frame, plus any fade. Take 12 frames at 0.5 s each: that is 12 times 0.5, or 6 seconds. With Forever it loops. With 3 times it plays 3 times and stops on its last frame, 18 seconds in all.

Common problems

• It shows one picture: the app or page you opened it in does not play APNG.
• The file is large: lower the width, or choose 256 colours. For a GIF instead, use the GIF maker.
• An animated WebP or APNG you dropped counts as one picture: only its first frame is read. Turn an animated WebP into a GIF with WebP to GIF first.
• The frames have different sizes: set Shape, and choose whether frames fit inside or fill and crop.

To save each frame of a GIF as a still, use GIF to PNG. To make a still PNG smaller, use Compress PNG.
