# Bit Studio vs Aseprite: Painting Pixels vs Composing Loops

*2026-10-21 — Design — By Kim*

> Aseprite and Bit Studio do different jobs. Aseprite is where you paint pixel art and make sprite sheets. Bit Studio doesn't paint at all: it takes finished sprite sheets and composes them into scenes that loop seamlessly, with lights, particles and distortions, and exports them everywhere, including live into Unreal Engine 5.
A question that keeps coming up: how does Bit Studio compare to [Aseprite](https://www.aseprite.org/)? It doesn't really. Aseprite is where you paint pixel art and make sprite sheets. [Bit Studio](/bit-studio) doesn't paint at all. It takes the sprite sheets you already have and composes them into scenes that loop forever. One makes the pieces, the other puts them together.

## Aseprite is where the pixels come from

Aseprite is a painting tool. Layers, frames, onion skinning, a walk cycle drawn frame by frame, and out it goes as a sprite sheet. It's very good at that, and Bit Studio doesn't try to compete with it. There's no brush in Bit Studio, no pencil, nothing to paint with. If a pixel needs to change, that happens in your painting tool.

## Bit Studio is where they come together

Bit Studio picks up from there and works more like a compositor. Somewhere between Photoshop's layer stack and After Effects' timeline, but for pixels.

You import a sheet as a bit, give it some motion, group bits into compositions and place those around the scene, mirrored, repeated or in a ring. Then lights, particles and distortions go on top, rendered on the GPU by [Blastwave](/news/blastwave-cross-platform-gpu-engine), our own engine.

The part I care most about is the loop. A part always plays a whole number of times inside its parent, so nothing ever jumps at the seam. Keeping track of that by hand in a frame-by-frame tool gets painful fast once a dozen things move at different speeds. I wrote a bit more about that in [how to make a pixel-art loop with no visible seam](/news/seamless-pixel-art-loops).

When the scene is done, Bit Studio exports it as MP4, WebM, GIF, WebP or APNG, in sizes for social media, as a Steam store kit, as print-size PNGs, as a web page or React component that plays it live, or straight into [Unreal Engine 5](/news/export-pixel-art-loops-to-unreal-engine-5). Aseprite exports the sheets themselves, ready for any engine. Two ends of the same pipe.

## Paint with light and dark in mind

One thing worth knowing before you paint for Bit Studio. It stores art as 16 gray levels. When you import a sprite sheet it's normalized to a 16-step gray ramp (alpha stays), and a theme decides the colors. That's why switching palettes costs nothing, and there are 460 of them built in.

It also means Bit Studio keeps your values, not your exact colors. Two colors with the same brightness end up as the same gray. So paint with light and dark in mind, check your shading in grayscale, and let the theme do the coloring. It also helps to paint the pieces separately (a gear, an eye, a sign) rather than one finished picture, since Bit Studio is where they get put together anyway.

## From one to the other

Paint the pieces in Aseprite and export each one as a sprite sheet. Import them into Bit Studio; Bits > Import folder of sheets... takes a whole folder at once. Then give them motion, build compositions, add light, pick a theme, and export.

Every scene on the [Bit Studio page](/bit-studio) was built from sprite sheets like this, and they're all playing live in your browser right now. So is the one at the top of this post:
