This online utility lets you check whether an animated or static GIF contains transparency. You can see the overall transparency result and find out which frames are fully opaque, fully transparent, or contain transparency. You can play the GIF at its original speed or with a custom delay, pause on a specific frame, and see transparent and opaque pixels highlighted in different colors.

This browser‑based program lets you check whether a GIF file contains transparency. As soon as you upload a GIF, the tool immediately runs a transparency check and displays the result as a status badge. The check is performed across all frames, ensuring that the transparency that appears only at certain moments in the animation is not missed. This makes it quick and easy to verify whether a GIF can be safely placed on any background or whether it contains transparent areas. For a more detailed inspection, the tool provides per-frame results. You can see which frames contain transparent and opaque pixels, which frames are fully transparent, and which frames are fully opaque. The tool also shows the exact number of transparent and opaque pixels in each frame. You can run the transparency check while the animation plays automatically using the original timing stored in the GIF, or apply a fixed frame delay to slow the process down and examine frame changes more carefully. If you need to check a specific frame, you can pause the animation and verify transparency at an exact frame index (frame indices start at 1). Because the GIF format supports only binary transparency, each pixel is classified as either fully transparent or fully opaque (semi-transparent pixels do not exist in a GIF). To make the results easier to read, the tool highlights transparent and opaque pixels in the output preview using different colors. These colors are used only for visualization during the check and do not modify the original GIF. In the options, you can select which color displays transparent pixels and which displays opaque pixels. Gifabulous!

In this example, we run a transparency check on the ice‑cream GIF using its original playback timing. The tool scans every frame and reports the status for each one. All frames are marked as opaque, meaning the entire file contains no transparent pixels. The badge result confirms the GIF is fully opaque, so it can be safely placed on any background without showing content underneath. (Source: Pexels.)
This example performs a transparency check on every frame of the Rocket Diver sprite from the Metal Slug series. To track the status of each frame, we use a custom frame delay and slow the playback to 300 ms per frame. The results show that frames 1 through 66 contain both transparent and opaque pixels, while frame 67 is fully transparent and contains no opaque pixels. Transparent areas are displayed in pink, and opaque areas are displayed in dark blue in the preview output. (Source: SNK.)
In this example, we first determine the overall transparency status of the GIF and confirm that it contains transparent pixels. The options panel shows that all frames include a mix of transparent and opaque pixels. We then stop the animation on frame 7 to inspect it in detail, where the tool reports the exact pixel counts, showing 87,535 transparent pixels and 34,965 opaque pixels in that frame.
