Animations

Animated images (GIF, APNG, WEBP), are very popular. An animation has several static images - frames, and the information, for how long each frame should be displayed (before going to the next frame). Photopea can open, edit and save animations.

Animations in Photopea

Photopea can make an animation from layers of the document by showing a different layer in each frame. To define a new frame, the layer name should start with _a_. It can be a regular layer, a folder of layers, or any other layer.

When you export such document as a GIF, PNG or WEBP, Photopea detects all layers starting with _a_. The first such layer is shown in the first frame (others starting with _a_ are hidden). The second such layer is shown in the second frame, etc.

Example: we have five layers: background, _a_dog, _a_cat, _a_tree, watermark. The GIF will have three frames (3 layers start with _a_). background and watermark will be in all frames. Try it here!

When you open an animation (GIF, APNG, WEBP) in Photopea, Photopea will turn every frame into a layer with a proper name. So when you edit an animation (delete frames, reorder frames, resize ...), there is no need to change layer names.

Delay

A layer which starts with _a_ makes a new frame, which will be shown for 100 ms by default. To set your own delay, put , and a number to the end of the layer name. E.g. _a_dog,500 will be displayed for half a second.

Merge frames

Let's say we have 3 frames of one animation and 3 frames of another, i.e. six layer starting with _a_. The resulting GIF will have six frames. Can we make these two animations play simultaneously "in parallel"?

We need to turn it into 3 frame layers, where each layer contains images from both animations. We can do it manually: merge each two layers into one using Layer - Merge Layers.

We can do it automatically. Put each animation in a folder and press Layer - Animation - Merge.

Photopea will find all folders, and merge their frames together. Alternatively, you can select only folders you want to merge (in Layers Panel) before pressing Layer - Animation - Merge.
