A GIF is a sequence of images without sound
GIF stores indexed images and their display timing instead of a video soundtrack. Each frame palette has at most 256 colors. That works well for a brief visual action, but photographic gradients and detailed footage can lose color detail. This tool builds a 256-color palette for each sampled frame and produces a silent repeating animation. If narration, music or subtle picture detail is essential to understanding the moment, keep a video version alongside the GIF.
Select the action before choosing dimensions
Use start and end times to isolate one complete action, such as opening a menu or showing a reaction. The selected range must be within the source and no longer than 15 seconds. Leaving the end blank selects the next five seconds or the remaining duration of a shorter video. A concise range often communicates more clearly than including the setup and aftermath. Watch the repeat point too, because a sudden jump from the final frame to the first can distract.
Balance width and motion against file size
Choose a maximum width of 320, 480 or 640 pixels and a frame rate of 10 or 15 fps. The tool keeps the aspect ratio, caps height at 640 pixels and does not enlarge a small source. A tall recording can therefore finish narrower than the selected width. Lower dimensions mean fewer pixels in each frame, while a lower frame rate means fewer sampled images. Start with the smallest setting that still makes the action and any essential text readable.
Know why conversion can make a larger file
A short GIF can outweigh the source video because the formats compress moving images differently. This page samples decoded frames and encodes them as a new animation; it does not copy the compressed video track. Compare the finished file size rather than assuming that a short loop is lightweight. If it is too large, shorten the range, lower the width or use 10 fps. The source must also be browser-decodable, within 500 MB and within the per-frame pixel limit.
