How can I compress or reduce gif file size to 1mb?

Windows itself has a built-in compression feature that works for GIFs without any quality loss.

Use Windows' Built-in Compression: You can use the native "Zip" feature in Windows File Explorer to compress GIF files into a ZIP archive.

How to reduce GIF file size to 1MB: Right-click the GIF file, go to the "Share" tab in File Explorer, or simply right-click and select "Send to > Compressed (zipped) folder". This will significantly reduce the file size for storage or transfer, though the file inside the archive remains unchanged until extracted.

To actually reduce GIF file size to 1MB, you would need a dedicated image optimizer that uses techniques like reducing colors or resizing the animation . These actually change the internal data of the GIF to make it smaller, which is different from just packing it into a ZIP folder.
