This is a tool for adjusting GIF animation speed, thus making it run faster or slower - correct wrong speed, make a slow motion GIF, speed up slow GIFs. It can also change APNG speed.

If you want to change animation speed proportionally to the current animation, use "% of current speed" from the drop down. Entering 200% will make animation run 2x faster, 50% will cause it to slow down 2x. Slowing down a GIF too much may cause it to lose smoothness.

Alternatively, you can specify precise delay time in one-hundredths (1/100) of a second between frames; a longer delay equals slower animation. If some frames in the original animation are displayed longer than others, this option will overwrite it and may distort the flow of the animation.

Warning: some browsers and image viewers (including Chrome) may ignore values smaller than 2 hundredths of a second, so if you enter 0 or 1, the animation will default to a slower speed when viewed in such programs. These are technically valid values but probably shouldn't be used.

If you want to manually enter different delays for specific frames or remove some frames altogether, you can do it in our GIF maker - split the image and click the "Edit animation" button.
