This online utility lets you clean the edges of animated or static GIF images. You can trim fixed-width strips from the borders, remove leftover pixels based on color similarity, and soften harsh edges with smoothing. You can also preview the GIF in the online player to instantly see how each frame looks after cleanup. Created by GIF experts from team Browserling.

This browser-based tool cleans the edges of animated GIFs. It removes visible lines, chroma key halos, and edge artifacts so the animation can be used seamlessly on any background. The process of creating a clean GIF image is divided into three main stages: trimming by distance, cleaning by color, and smoothing the edges. Edge trimming allows you to remove a specified number of pixels along the border of each frame. Here you can control how the cleaning process behaves. By activating the "Skip Internal Cuts" checkbox, you ensure that the cleaning process only affects the outer perimeter of the objects, preserving the edges of any holes or transparent areas inside the main shape. By toggling the "Trim Border-contact Pixels" option, you can choose whether or not to remove all pixels that touch the four sides of the GIF frame. Cleaning by color lets you delete edge pixels of a specific color. Set the edge color you want to clean, or leave this field blank to allow the tool to automatically detect the dominant edge color. You can adjust the cleaning intensity with the "Color Threshold" parameter (for example, "20%") and select the color comparison method between "RGB Distance" and "Perception Match". You can also set the "Color Cleaning Depth" to set at what distance from the edge the tool should search for matching pixels. GIF files do not natively support partial transparency (they only allow for full opacity or full transparency). However, when the edges of a GIF appear jagged, and you know what background color the GIF will be displayed on, you can simulate a semi-transparent look along the edges. To do this, enable the "Edge Smoothing" mode, set the "Smoothing Radius", and choose the "Background Color" that will show through the semi-transparent pixels. This trick creates the illusion of transparency when the animation is used on that specific background color. To see the result of all cleaning operations, activate the "Animation Preview" and view detailed information about the frames, their delays, and sizes in the information section of the tool options.

In this example, we remove a bright green chroma background surrounding an animated emoji GIF. We apply only the edge pixel trimming method by setting the stroke width to 4 pixels. The animation consists of 28 frames, and when the GIF player is enabled, you can see that each frame has been uniformly cleaned from the outer green border. (Source: Pexels.)
This example removes flickering, noisy white pixels that appear inconsistently around the perimeter of the animated sprite for the character Goro Daimon from The King of Fighters series. These noisy pixels vary in density across the character's boundary in each of the 15 frames. To ensure a clean result, we apply "Color-Specific Cleaning" and trim 1 pixel from the edge. We leave the edge color field blank to allow the tool to auto-detect the dominant white noise color, and we set the color threshold to 25% to remove colors closely matching the artifact color.

In this example, we make a full cleanup of a single-frame GIF of a perched bird surrounded by orange edge artifacts. We first use the pixel trim of 2px to cut a base layer. Then, we utilize the color-specific cleaning by removing orange pixels with 30% similarity and 40px depth. We activate the "Clean GIF Frame Borders" to strip the orange pixels from the branch where it touches the frame edge, and we disable the "Remove Outer Perimeter Pixels" to ensure the orange pixels between the bird's feet are also removed. Finally, we enable "Edge Smoothing" with the background color set to "skyblue" to create a seamless, non-jagged edge transition for use against a sky background. (Source: Pexels.)
