Capture In-Game Screenshots in Godot

Animation of a game saving, with a screenshot appearing on the save screen

Godot allows you to capture in-game screen-shots, without the use of any plugins/addons. However, I couldn't find a complete, step-by-step guide to do this, without relying on any specific nodes being instantiated in your scene.

You can follow these steps. I tested these on Godot 3.0.6. Some of the code originated in a thread that mentioned that "you need this prior to Godot 3.1," but through testing, I eventually removed all unnecessary code. I can confirm that this sample works, because I implemented it in Eman Quest.

Saving Screenshots

Godot provides a rather straight-forward API for saving a screenshot:

var screenshot_path = "user://screenshot-test.png"

# Retrieve the captured image
var image = get_tree().get_root().get_texture().get_data()

# Flip it on the y-axis (because it's flipped)


This saves a screenshot into a file called screenshot-test.png, under the user space; on Windows, that's something like C:\Users\CURRENTLY_LOGGED_IN_USER\AppData\Roaming\Godot\app_userdata\Eman Quest\screenshot-save0.png, where CURRENTLY_LOGGED_IN_USER is your user name (eg. nightblade).

Loading Screenshots

Loading screenshots proves more complicated:

  • To load the data, you can use image.load_png_from_buffer, but it takes a PoolByteArray - not something you can load with a call to preload("res://..."). This requires using the File API.
  • To set the texture onto a sprite, you cannot simply assign it to an Image instance; instead, you need to create and initialize an ImageTexture instance.

After we sort through these issues, we end up with code like this:

var file ="user://screenshot-test.png", File.READ)
var buffer = file.get_buffer(file.get_len())

var image =

var image_texture =

sprite.texture = image_texture

This loads the PNG file screenshot-test.png from the user-space into an Image, wraps it into an ImageTexture, and assigns it to some Sprite instance

Crop and Scale

Since we loaded our PNG into a Sprite, we can execute other operations on it:

  • You can set the region_rect properties (through code or through the editor) to crop the image
  • You can set the scale to create a thumbnail of the image
  • You can apply effects, colourization, etc.

This affords a lot of interesting use-cases, such as creating a thumbnail of the in-game screen per save-game (my personal use case).
