Upscale Godot sprites without blur.

1. Fix texture filtering before enlarging the file

Keep your original PNG while checking the engine. In Godot 4, open Project > Project Settings > Rendering > Textures > Canvas Textures and set Default Texture Filter to Nearest. Check the sprite's own Texture Filter and its parents too: a CanvasItem can override the inherited filter. See the Godot CanvasItem reference.

Godot 3 uses a different workflow: select the PNG in the FileSystem dock, disable Filter in its Import settings and click Reimport. See the Godot 3.6 import guide.

2. Check viewport scaling and camera movement

For a low-resolution Godot 4 pixel-art project, choose your intended base viewport size, use Stretch Mode: viewport, and use Stretch Scale Mode: integer in Godot 4.2 or later. Integer scaling can leave black bars when the window is not an exact multiple. These are the settings in Godot's pixel-art resolution guide.

If the sprite is sharp when still but shimmers during movement, inspect camera smoothing, fractional positions, zoom and rotation. A larger source PNG does not correct a fractional runtime transform. If neighboring frames leak into an atlas region, inspect its rectangle, padding and sampling settings separately.

3. Enlarge only when your workflow needs a bigger PNG

Pre-enlargement can be useful for a fixed-size export or a pipeline that requires larger texture files. The tool above produces a static PNG; it does not import animation timing, tags, pivots or engine resources. If Nearest and integer viewport scaling solve your game's display, you can keep the native-size asset.

Try the original eight-frame example

Download the original 64×32 PNG and the nearest-neighbor 4× PNG. The original has four columns and two rows: eight 16×16 cells. The enlarged sheet is 256×128 with 64×64 cells. In Sprite2D, assign either texture, then set Hframes = 4 and Vframes = 2; those counts stay the same.

If you replace the native texture with its 4× copy, a Sprite2D Scale of 0.25 preserves the original on-screen size. Importing a sheet alone does not create an animation: configure frame order and timing in your engine. The downloadable Godot example project includes native and enlarged assets; its README records the target version, setup and validation scope.

Choose a native sprite task

Follow the tested engine sprite workflows for ordered animation, irregular AtlasTexture regions, inherited filter overrides or integer viewport scaling. Each includes an original runnable project and an inspected native result.
