制作动态 GIF——免费

Drop two or more images in the order you want them to animate, adjust frame delay, output width and quality, then Render GIF. Frames are uploaded over HTTPS and encoded into a GIF on our secure server (deleted automatically afterwards), and the result downloads as animation.gif — ready to drop into Slack, Discord, GitHub, or anywhere else GIFs are welcome.

若要让动态看起来自然，每帧 100-150 毫秒可获得约每秒 7-10 帧的效果——如同经典动画。50-80 毫秒显得现代而利落。300-500 毫秒则营造出刻意的「幻灯片」节奏，适合前后对比或产品展示。请根据内容类型匹配相应的延迟。

对于聊天平台和社交媒体，480-720px 宽是理想区间——在手机上清晰，上传也快。对于嵌入博客的 GIF，640-800px 是标准尺寸。超过 1280px 会使文件变得很大，却几乎没有视觉提升，因为 GIF 最多只支持 256 色。

GIF 每帧仅支持 256 种颜色。照片内容（肤色、渐变、夕阳）是最难处理的情形。调低「质量」滑块的数值（数值越小，颜色量化越好，但编码越慢），抖动效果就会改善。或者改用 MP4/WebM 来呈现真彩色动态画面。

可以——每一帧都会以信箱模式置于统一的画布上（与第一帧的宽高比一致），背景为白色，因此混用竖版和横版帧不会破坏动画。为获得一致的效果，建议先用我们的图片尺寸调整工具将源图片调整为相同尺寸。

可以——「无限循环」开关默认开启。关闭它即可生成只播放一次的 GIF（在实况活动捕捉和教学内容中，有时更希望观看者停留在最后一帧，这时就会用到）。

Your frames are uploaded over HTTPS to our secure server to be encoded into a GIF, then deleted automatically after processing — we never store or share them. For content under a strict no-upload data-residency rule, a fully offline desktop GIF encoder is the safer choice.

免费、帧数不限、输出无水印、无需注册。编码器速度足够快，即便是 50 帧的动画，在普通笔记本电脑上也能在 30 秒内完成。

不能直接转换——这款 GIF 制作工具是用图片帧（JPG、PNG 或 WebP）来生成动画，而非用视频文件。要把一段视频片段做成 GIF，请先把它的帧导出为图片（大多数视频播放器和编辑器都能保存某一帧或截图序列），然后按你想要的播放顺序把这些图片拖到这里并渲染成 GIF。

拖入 JPG、PNG 或 WebP 图片，包括透明 PNG。不同尺寸的帧会以加边框（letterbox）方式置入同一画布，因此竖向和横向照片混合时仍能流畅地连成动画。帧数没有上限，整个 GIF 都在你的浏览器中合成，因此不会上传任何内容。

In the Frames panel, drag any frame thumbnail by its grip handle to a new position in the strip, or use the compact left/right reorder arrows on mobile-sized screens. The GIF automatically rebuilds a few hundred milliseconds after you drop a frame, so you can preview the new order without pressing a separate rebuild button.

Yes — the Add frames button in the Frames panel lets you drop in additional images at any point; they're appended to the end of the sequence and you can then drag them into position. The GIF re-encodes automatically each time you add, remove or reorder a frame.

For a clear product walkthrough, use a longer delay around 400-600ms so viewers have time to read each step, a width of 640-800px for crisp detail on blog and documentation pages, and a Quality value around 5-10 for cleaner color reproduction on product photography. Lower quality numbers trade a slightly longer encode time for noticeably less color banding on gradients and skin tones.

Click the trash icon on any frame's thumbnail in the Frames panel to delete just that image — the GIF rebuilds automatically a few hundred milliseconds later using the remaining frames in their existing order. Keep in mind a GIF needs at least two frames to animate, so if you delete down to one, add another image before Render GIF produces anything.
