GIF frame splitter (extractor/decompiler)
This online tool is designed to convert an animated gif image into individual frames for editing or viewing them separately.
After decompressing the gif file, you can download specific frames (right click > save image as...) or all at once as a single zip file, by clicking "Download frames as ZIP."
If you want to rearrange frame order and restore animation, click "Edit animation" button.
