GIF Speed Changer - Free Online | FunToolX

After uploading the GIF file, select a speed multiplier: 0.25x (slow speed), 0.5x, 1x (original speed), 2x, 3x, 4x, etc. The tool modifies the delay time for each frame (each frame in the GIF format has a delay field in 10ms) to change the playback speed. The number of frames and image quality remain unchanged.

The frame delay of GIF is stored in the Graphics Control Extension (GCE) block for each frame, in units of 10 milliseconds. Acceleration is dividing the delay value by the multiplier, and deceleration is multiplying the multiplier. The tool parses and rewrites these fields on the browser side without re-encoding pixel data, so the image quality is intact.

It is suitable for adjusting the speed of the emoji pack. If you are too fast and you can't see clearly, you can slow down, and if the rhythm is too slow, you can accelerate. It is also used to adjust the animation speed to match the rhythm of the music.

Online GIF speed changing tool, adjusts the playback speed of GIF animations, supports acceleration and deceleration, is achieved by modifying inter-frame delay, and handles it locally in the browser.
