GIF Frame Extractor and Rebuilder — Browser Image Tool
ImageGIF Frame Extractor and Rebuilder decodes an animated GIF in the browser, exports frame PNGs, and encodes a rebuilt GIF.
What is it
GIF Frame Extractor and Rebuilder reads GIF frames and delay metadata in your browser, composites full frames on Canvas, exports each frame as a PNG, then encodes a new GIF with the same order and delays. Files are not uploaded to a server, and large files are limited to protect browser memory.

FAQ
Is the GIF uploaded?
No. Decoding and rebuilding run inside this browser.
Will the rebuilt GIF be identical?
Frame composition and delays are reused, but colors are quantized again, so size and color can differ from the original.
