Upload a before and after image, adjust the animation settings, and export an animated sliding-reveal GIF — no account needed.
Upload your "Before" and "After" images (JPG, PNG, or WebP). A live preview shows the comparison slider immediately.
Set animation duration (1–5s), output width, reveal direction (left-to-right or right-to-left), and frame rate.
Click "Create GIF" to generate the animated file. A progress bar tracks rendering. Download when ready.
The GIF animates a vertical divider sweeping across the image, revealing the "After" photo as it moves. A white handle with arrows is drawn on the divider to make the comparison clear.
No. Both images are scaled to the same output dimensions. For best results, use images of similar dimensions and subject framing so the comparison makes sense.
Lower the output width (e.g. 400px), reduce the animation duration, or lower the frame rate. All three directly affect the number of frames and pixels encoded, which is the main driver of GIF file size.
Each image can be up to 10 MB. Very large images may take a moment to render each GIF frame, but all processing happens in your browser.
