Animated GIF analyzer

Analyze animated GIF images

This tool allows you to inspect the internal structure and metadata of animated GIF images. Upon uploading a GIF, it provides a summary of global statistics, including logical screen dimensions, file size, total frame count, loop count, and the global color table (palette). It is a useful utility for debugging broken GIFs, optimizing file sizes, or understanding how a specific animation is constructed. It can extract the color palette as a list of hex colors.

Beyond global statistics, the analyzer breaks down the image frame by frame. For each individual frame, you can view its specific dimensions, x/y offsets (position on the canvas), and duration (delay time). If the GIF uses local color tables for specific frames - a technique often used to bypass the 256-color limit - these local palettes will be extracted and displayed alongside the frame. A visual preview with a red border shows exactly where each frame is positioned on the canvas.

The tool also reports the 'Disposal Method' for every frame, which tells the decoder what to do with the current frame after its display time expires. Common methods include: 'Do not dispose' (the next frame is drawn on top, often used for transparency optimization), 'Restore to background' (the area is cleared to the background color), and 'Restore to previous' (the canvas reverts to the state before the current frame was drawn). Understanding these methods is crucial for fixing graphical glitches in transparent animations.

This GIF analyzer is completely free to use online tool. All uploaded files are processed safely and are automatically deleted from our servers one hour after upload to ensure your privacy.
