Frequently Asked Questions

The tool extracts all frames from your animated GIF, adjusts the delay between frames based on your chosen speed multiplier, then re-encodes the GIF with the new timing. All processing happens locally in your browser.

You can choose preset multipliers: 0.25x (4x slower), 0.5x (2x slower), 1x (original), 2x (double speed), or 4x (quadruple speed). You can also set a custom frame delay in milliseconds for precise control.

The visual quality and frame content remain identical. Only the timing between frames changes. However, the re-encoding process may slightly affect file size depending on the compression settings used.

Yes. The tool displays both the original and modified GIF side-by-side with their playback speeds, total duration, and frame count so you can compare before downloading.

At 4x speed, animations play very quickly - best for long, slow animations. At 0.25x speed, animations become much slower - ideal for analyzing motion or creating slow-motion effects. Browser performance may vary with extreme speeds.

Yes, it works with any valid animated GIF file. Single-frame (static) GIFs can be processed but won't show speed changes since there's no animation. Corrupted GIFs may fail to parse.

Yes. Use the custom delay input to specify exact milliseconds between frames. Lower values create faster animations (e.g., 20ms = ~50 FPS), while higher values slow down playback (e.g., 200ms = ~5 FPS).

Yes. The output is a standard GIF file compatible with all browsers, email clients, social media, and messaging apps that support animated GIFs. Speed changes are baked into the file permanently.

No. All processing happens locally in your browser using JavaScript. Your GIF never leaves your device and is never uploaded to any server. Everything is private and secure.

Currently, the tool processes one GIF at a time. To process multiple files, load each one individually, adjust the speed, and download. This ensures you can fine-tune speed settings for each animation.
