What is the boomerang effect?

Boomerang plays the GIF forward then immediately backward in a seamless ping-pong loop, creating a back-and-forth animation.

How does the boomerang tool work technically?

It takes the original frames, appends a reversed copy (excluding the first and last frames to avoid duplicate boundary frames), then encodes the combined sequence as a new GIF.

Will the output GIF be twice as long?

Almost — the output has roughly 2× the frames (minus 2 boundary frames) so the animation takes about twice as long per cycle.

Will the boomerang GIF be twice the file size?

Approximately, yes. Since frames are doubled, the file size roughly doubles as well.

Can I apply boomerang to any GIF?

Yes. The tool works with any valid animated GIF, regardless of size or number of frames.

Does boomerang preserve frame delays?

Yes. Frame delays are preserved — the reversed portion uses the same timing as the original.

Can I combine boomerang with other effects?

Yes. Apply Boomerang first, then use other tools (filters, watermark, speed) on the resulting GIF.

What's the difference between Boomerang and Reverse?

Reverse plays the GIF only backward. Boomerang plays forward then backward continuously in a loop.

Can I control how many times the boomerang cycles?

Use the GIF Loop tool after applying Boomerang to set a specific loop count.

Is the original GIF modified?

No. A new boomerang GIF is created in your browser. Your original file is not changed.
