GIF Image
ImagesA palette-based image format. GIF89a can carry multiple timed frames; palette limits affect photographic gradients, and a static export discards motion.

First: choose for your purpose
GIF may be static or animated. Seeing one frame can mean viewer limitations rather than corruption. Palette/transparency limits matter for photos and semi-transparent artwork.
Opening steps
Choose your environment or purpose to see its steps.
Menu labels and support vary by app, OS and version. Preserve the original before making changes.
Troubleshooting by symptom
- If a preview is static, test in a browser. A single-frame GIF has no animation.
- Stopping may reflect loop count or damage; banding can arise from palette reduction.
- Only first frame: compare in a browser to distinguish static content from viewer limitations.
- Ghosted background: inspect frame disposal/compositing and transparency.
- Posterized photo colors: palette limits can cause this; select JPEG/WebP for photos or MP4 for video as appropriate.
GIF → PNG (still image)
- Choose the required frame in an image editor.
- Export PNG and verify that the intended frame was saved.
- Verify motion, frame order/duration, looping, color and transparency.
A single PNG does not retain frame timing or motion. Video conversion must process all frames.
Before converting to a still image
Choose which frame to export as PNG/JPEG; ordinary still images do not retain motion, delays or looping.
For instructions, export key frames with their order; choose animation/video formats if motion must survive.
Palette and transparency limits
GIF color tables support up to 256 entries and do not offer full partial-alpha transparency; photos/soft shadows can change.
Check animation/timing options in GIMP export and retain editing data and the source GIF.

Related-format differences
| Format / choice | Purpose and preserved information |
|---|---|
| GIF | Static/animated with palette and alpha limits. |
| PNG | Useful for still-image alpha; animation needs separate support. |
| WebP / MP4 | Alternative motion delivery; check support/audio requirements. |
Handling and security
Avoid autoplay when motion is disruptive. Image format alone does not certify safety.
Questions and answers
Why is a GIF static?
It may be a single-frame image or the viewer may show only the first frame.
Why do photos lose smooth colors?
Palette limits can replace colors. Compare a photographic format such as JPEG.
Does GIF-to-JPG retain motion?
Ordinary JPEG is static. Use animation or video output to retain motion.
Does GIF→PNG retain animation?
Ordinary still PNG does not; distinguish frame selection from animated output.
Is a GIF stopping after one play defective?
It may be the repeat-count setting; compare source and player.
