This online utility lets you erase strokes around objects across all GIF frames. In the tool options, you can define how many pixels to strip from the edges, enable deeper scanning for strokes stuck in folds or crevices, and fine-tune color detection to match the stroke precisely. You can also enable edge refinement and preview the cleaned animation frame by frame. Created by GIF experts from team Browserling.

This browser-based tool removes unwanted strokes surrounding objects in animated GIF files. It cleans up image elements placed on transparent backgrounds, where isolating or cutting out an object often leaves behind a harsh, pixelated border. Most of the stroke pixels can be removed with a single option. By setting the stroke thickness in the first group of settings, the program erases all stroke pixels around GIF objects within the specified width. This makes it easy to quickly remove a thick stroke. To prevent internal transparent areas (holes) from expanding when removing the stroke, activate the "Focus on Outer GIF Edge" option. This ensures the stroke removal process is applied only to the exterior perimeter of the GIF object, preserving the size of any existing transparent regions within the subject. For more precise cleaning of leftover strokes, you can use the advanced stroke detection options. These settings specialize in removing stroke pixels hidden in folds and tight corners of objects, based on the color identification of the stroke. The program can automatically detect the stroke color (leave the color field blank for auto-detection) based on the pixels already removed within the specified thickness, or you can specify the stroke color manually. The tool compares the colors of edge pixels with the chosen stroke color, and if they match, it removes them. For color comparison, you can choose between two algorithms: direct RGB comparison or a method based on human visual perception (delta-e). Additionally, you can adjust the color sensitivity threshold (in percentages), which defines how closely a pixel must match the stroke color before being deleted, and set the stroke depth, which controls how far inward the removal reaches from the edges. At this stage, your GIF will be fully cleaned of strokes. You can then apply edge smoothing. Normally, smoothness in digital images is achieved with semi-transparent pixels, but GIF files do not actually support true semi-transparency. To solve this, the tool simulates smoothing by blending with a chosen background color. For example, if you plan to use the GIF on a white webpage, select white as the background, and the tool will generate smooth edges that appear semi-transparent against that background. The final options block allows you to turn the GIF animation on or off if it has more than one frame, and also displays information about the frame count, frame size, and frame delay. This tool removes strokes, but if you want to create a stroke around a GIF, use the Add a Stroke to a GIF tool. Gifabulous!

In this example, we remove a vivid plum-colored stroke from a looping 31-frame OK hand GIF. We apply a stroke width of 6 pixels to erase most of the plum edges. Also, we enable deep stroke detection to remove leftover pixels between the fingers, especially in the final GIF frames. We use a 120-pixel removal depth and a 20% color threshold. Also, we intentionally disable the "Focus on Outer GIF Edge" option so that the inner ring formed by the fingers is also cleaned. (Source: Pexels.)
In this example, we clean up a sprite animation of The Mars Mecha (from Metal Slug 3), which is surrounded by a distracting blue stroke. The GIF has 8 frames, and we remove the border using a 3-pixel stroke width while restricting cleanup to the outer edges. To improve accuracy, we enable advanced deep stroke detection with a 12% color tolerance and a 5-pixel removal depth. (Source: SNK.)
In this example, we process a static GIF (only one frame) of a blue cosmos flower, which is surrounded by a very wide stroke that gives the appearance of an orange glow against the white background. We set a large stroke thickness of 13 pixels to trim the wide edge and enable advanced stroke removal with a 40% sensitivity threshold, using Euclidean color comparison. To make the edges smoother, we apply edge refinement with a radius of 3 pixels and specify white as the background. As a result, the flower blends seamlessly into a white surface without jagged edges. (Source: Pexels.)
