Common questions about the free online gif metadata viewer.

A GIF stores its version, screen size, colour tables, background index, pixel aspect ratio, loop count, and per frame a delay and disposal method.

Load the GIF and the report lists every frame with its delay in milliseconds, plus the total animation time.

It comes from the NETSCAPE application extension. Zero means the animation repeats forever, a number means it plays that many extra times.

It tells a player what to do with a frame before drawing the next one, such as leaving it, restoring the background or restoring the previous frame.

It describes the shape of a pixel. Zero means square pixels, which is normal for almost every GIF on the web.

Some encoders put a separate local colour table on every frame instead. The report lists those local tables per frame.

Yes. Comment extension blocks are decoded as text and shown in the report along with any application extensions.

No. The file is read with the File API and inspected inside your browser; nothing is transmitted.

Yes, it is free with no account, no sign-up, no limits and no advertising trackers in the tool itself.
