Frequently Asked Questions

What animated image formats are supported?

This tool supports GIF, animated WebP, APNG (Animated PNG), and animated AVIF files. It can extract frame-by-frame information from all these formats.

What information can I see for each frame?

For each frame, you can see the position (x, y offset), dimensions, delay time, disposal method, transparency settings, and format-specific details like blend modes and local color tables.

Can I download individual frames?

Yes! Click the 'Download Frame' button to download the currently selected frame. The frame will be saved in the same format as the source image when possible, or as PNG as a fallback.

What does 'disposal method' mean?

The disposal method tells the viewer what to do with a frame after displaying it. Options include 'none' (leave the frame), 'restore to background' (clear to background color), and 'restore to previous' (restore the previous frame).

Is my data safe?

Yes! All analysis is performed locally in your browser. Your animated images are never uploaded to any server - everything happens on your device.

Why does my GIF show a different duration than expected?

GIF frame delays are stored with a minimum resolution of 10ms. Some GIF creators use very short delays (like 0ms or 10ms) which browsers often interpret as ~100ms. This tool shows the actual stored delay values.
