- Drop an animated GIF, WebP or APNG into the box.
- Read the details: frame count, total duration, average frame rate and size per frame.
- Scroll the thumbnails to see each frame and its delay.
About this tool
Find out why an animation is slow, huge or choppy. The analyzer reports the number of frames, total playing time, average and fastest frame delay, frame rate and how many bytes each frame costs.
That makes it easy to decide whether to drop frames, resize or lower the frame rate. GIFs are analyzed in every browser; animated WebP and APNG need a Chromium-based browser.
Frequently asked questions
How do I check the frame rate of a GIF?
Drop the GIF in. The analyzer shows frames per second calculated from the real frame delays.
Why is my GIF so big?
Look at frames and size per frame. Many frames at a large size add up quickly. Resize the GIF or drop every other frame.
Does it work with WebP animations?
Yes in Chrome, Edge and other Chromium browsers.
Is Animated Image Analyzer really free?
Yes. You can use Animated Image Analyzer as often as you like with no sign-up, no watermark and no daily limit.
Are my images uploaded to a server?
No. Animated Image Analyzer runs entirely in your web browser, so your files stay on your own device and are never sent to DEWANARO or anyone else.
