Yes, as long as the file is a valid animated GIF and under 20 MB. Very large or extremely old GIF formats might occasionally fail to decode properly, but the vast majority of standard GIFs work perfectly.
After processing, the reversed animation appears in the preview card. Simply click the "Download Reversed GIF" button underneath it to save the file to your device.
The reversed GIF is re‑encoded from individual frames, which can change file size depending on the original compression. We preserve frame delays accurately, but minor variations in colour or size may occur due to the encoding process. The result remains a fully functional animated GIF.
