How to Export Animations as PNG Sequences in Aseprite

This is a quick note on how to export an animation as a sequence of PNG images—one image per frame—in Aseprite.

Introduction

By default, Aseprite exports animations in GIF format.

This is a guide on exporting animation frames as PNG sequence images (img1.png, img2.png...) instead of a GIF.

How to Export Animation as PNG Sequence Images

It’s actually pretty simple.

Just set the file format to PNG when exporting, and Aseprite will automatically output a sequence of PNG files.


1. Open the Export menu

From the top menu in Aseprite, select "File > Export > Export As..." to open the export screen.


2. Set the output file name with .png format

In the export screen, choose any filename that ends with .png.

Specify any filename ending in .png


3. Click the Export button

Clicking the "Export" button will show a confirmation alert that frames will be exported as a sequence of images.

As the alert indicates, the image sequence will have frame numbers appended to the end of the filename (e.g., test1.png, test2.png...).


4. Click the Agree button

Click "Agree" in the alert window to export each animation frame as a numbered PNG image.

Tip: Customize the Filename for PNG Sequences

If you want to control where the frame number appears in the filename, you can use {frame} in the filename.

For example, if you set the filename as {frame}_test.png, the output will be 1_test.png, 2_test.png, and so on.

Use the {frame} placeholder to specify where the frame number goes

The {frame} part is replaced with sequential numbers in the output

Conclusion

There’s no special option for exporting as an image sequence—you just need to choose PNG format. This was a bit of a blind spot for me.

Hope this helps someone out there!
