What information does the GIF Analyzer show?

It displays dimensions, frame count, file size, frame delays, loop count, color count, and individual frame thumbnails.

Can I use the Analyzer to diagnose a broken GIF?

Yes. The Analyzer shows frame-level details that can reveal corrupt frames, missing data, or unusual delay values causing playback issues.

How do I check the frame rate of a GIF?

The Analyzer shows per-frame delay in milliseconds. Divide 1000 by the delay value to get FPS (e.g., 100ms delay = 10 FPS).

Does the Analyzer modify the GIF?

No. It is read-only. The GIF is parsed and inspected without any modification.

Can I export the analysis report?

You can copy the displayed information manually. A CSV/JSON export feature may be added in a future update.

Why does the Analyzer show more frames than expected?

Some GIFs use hidden sub-frames or micro-frames with very short delays for special effects. These all count as individual frames in the raw data.

What does 'loop count' mean in the Analyzer?

Loop count indicates how many times the animation repeats. A value of 0 typically means infinite loop. Some GIFs have no loop extension, which means they play once.

Can I analyze a GIF URL directly?

Currently only local file upload is supported. Download the GIF to your device first, then upload it to the Analyzer.

What is the color table size?

The color table stores the palette of up to 256 colors used in the GIF. Each frame may have its own local color table or share a global one.

Why do frame dimensions differ from the GIF dimensions?

GIF frames can be smaller than the canvas — they are positioned at a specific offset within the larger canvas. This is called frame patching.

GIF Analyzer

Inspect the internal structure of any GIF: frame count, dimensions, delays, color tables, and more.

Upload GIF to Analyze

Drag & drop or click to select

Inspect the internal structure of any GIF file: frame count, individual frame delays, canvas dimensions, color table size, and loop count — all displayed instantly after upload.

Useful for debugging animation timing, verifying export settings, or understanding why a GIF behaves unexpectedly. No data leaves your browser during analysis.

Guide: GIF Analyzer

When to use it

Check why a GIF plays too fast, too slow, or stutters by reading each frame's delay.
Confirm a GIF's dimensions and frame count before uploading it somewhere with strict limits.
Find out whether a GIF loops forever or stops after a few plays.

Tips

Look at the frame delays first. Very short or uneven delays usually explain jerky playback.
Use the frame thumbnails to spot duplicate or blank frames you may want to remove.
Compare the file size with the frame count to judge whether compression will help.

Good to know

Fix uneven timing with GIF Speed and change repeat behavior with Loop Count.
Remove problem frames you found here with Frame Editor.
Analysis runs in your browser; the GIF is never uploaded.
