Exporting frames from Aseprite usually means loading them into Godot just to check timing. Sprite Animation Previewer eliminates that round-trip. Upload frames, adjust FPS live, export a GIF.
It plays back a sequence of image frames as a looping animation directly in the browser, with no engine import and no install. Upload your PNG frames, hit Play, and watch the walk cycle or attack sequence in real time.
001.png, 002.png for correct order.Frame rate is one of the most important creative decisions in pixel art animation. Discrete, visible frame changes define the aesthetic.
There is no single correct answer — preview the same animation at different FPS values before committing.
The exported GIF uses a global 256-color palette built from the most frequent colors across all frames. Pixel art typically uses 4-64 colors, so coverage is exact with no quality loss.
This tool fits the Aseprite → export → verify → share pipeline. Animate with tagged layers, export each tag as a PNG sequence, then preview here to verify timing.
The GIF format supports a single transparent color index. Any pixel with less than 50% opacity in your source frames is mapped to the transparent slot in the palette. Fully or partially transparent pixels all become transparent in the exported GIF — GIF does not support partial (alpha-blended) transparency.
GIF is limited to 256 colors per file. If your frames contain photographs or complex gradients with thousands of colors, the palette reduction will cause visible banding. For pixel art with limited color palettes this is never an issue. For photographic source images, consider using WebP or APNG instead.
Common FPS values for game animations are 8, 10, and 12 for pixel art character sprites, and 24 or 30 for smoother effects. Use the real-time preview to dial in the timing before exporting. The FPS presets (6, 8, 10, 12, 24, 30, 60) cover the most common game animation standards.
Yes. The preview panel plays your animation in real time at the selected FPS. Use the Play/Pause button, step through frames with the arrow controls, or click any frame in the strip to jump directly to it. Adjust FPS and see the result instantly without re-exporting.
Frames are displayed in the strip in the order they were uploaded. Name your files with sequential numbers before uploading (e.g. run_001.png, run_002.png) to ensure they load in the correct animation order. You can drag frames in the strip to reorder them after uploading.
Currently the tool exports animations as GIF, which is the most universally supported animated image format in browsers and on social platforms. GIF is ideal for pixel art with limited color palettes. If you need WebP or APNG for better quality, export the GIF and convert it using a desktop tool like FFmpeg or EZGIF.
There is no hard frame limit. The tool runs entirely in your browser using the Canvas API. In practice, animations with up to 60–100 frames work smoothly on any modern device. Very large frame counts with high-resolution images may slow down the GIF export step, as each frame must be color-quantized and LZW-encoded in the browser.
A smooth loop comes from the source animation — the last frame must transition naturally back to the first frame. Common techniques include drawing the "return" portion of the motion explicitly as extra frames, or using an easing curve that brings the animated element back to its starting position. Once the frames are correct, the GIF export will loop them seamlessly.
Yes. Use the zoom buttons (1×, 2×, 4×, 8×) below the preview canvas to scale up the display. The canvas uses nearest-neighbor rendering (imageSmoothingEnabled = false), so pixel art stays sharp at any zoom level without blurring. The zoom only affects the preview display — the exported GIF is always at the original frame resolution.
Yes. The exported GIF includes the Netscape 2.0 application extension that instructs all GIF-compatible viewers to loop the animation forever. The in-browser preview also loops continuously by default. You can toggle looping off in the preview using the loop button, but the exported GIF always loops — GIF does not support a built-in "play once" option in the same way that video formats do.
