導(dǎo)出幻燈片為圖像：在PowerPoint中選擇“文件”>“導(dǎo)出”>“更改文件類型”，選用PNG或JPEG格式並保存所有幻燈片為單獨圖像；2. 使用工具創(chuàng)建動畫GIF：可通過在線工具（如EZGIF.com）上傳圖片序列並設(shè)置幀延遲生成GIF，或使用Photoshop將圖片導(dǎo)入圖層後通過時間軸製作幀動畫並導(dǎo)出，也可用GIMP或ScreenToGif等桌面軟件組合圖像序列；3. 優(yōu)化GIF文件：調(diào)整圖像尺寸、減少顏色數(shù)量、增加幀延遲或跳過次要幻燈片，並利用EZGIF壓縮或GIFski等工具降低文件大小以提升分享效率。整個過程簡單易行，借助免費工具即可完成高質(zhì)量動畫GIF製作，最終結(jié)果需確保播放流暢且便於傳播。

You can turn a series of PowerPoint (PPT) slides into an animated GIF by first exporting the slides as images and then combining them into a GIF using image editing or conversion software. Here's how to do it step by step:

1. Export Slides as Images from PowerPoint

Before you can create a GIF, you need to save your slides as individual image files.

Steps:

• Open your PowerPoint presentation.
• Go to File > Export > Change File Type .
• Choose an image format (eg, PNG or JPEG ). PNG is recommended for better quality and transparency support.
• Click Save All Slides to export every slide as a separate image.
• Choose a folder to save the images and confirm.

Make sure your slides are in the correct order and timing isn't needed yet — GIF tools will handle the animation speed later.

2. Use an Image Tool to Create the Animated GIF

Once you have the images, use one of the following methods to assemble them into a GIF.

Option A: Use Free Online Tools (easiest)

• Go to a free online GIF maker like:
  • EZGIF.com
  • Imgur (upload as album, then animate)
  • Online-Convert.com
• Upload your exported slide images in the correct order.
• Set the delay between frames (eg, 1–3 seconds per slide, depending on how fast you want it to play).
• Click “Create GIF” or “Convert” and download the result.

Tip: On EZGIF, you can also optimize the file size, resize, or loop settings.

Option B: Use Software Like Photoshop (more control)

• Open Adobe Photoshop .
• Go to File > Import > Video Frames to Layers (you can import a video, but for images, use File > Scripts > Load Files into Stack ).
• Select all your exported slide images.
• Once loaded as layers, go to Window > Timeline to create a frame animation.
• Convert layers to frames, set the delay time for each, choose loop options, and export via File > Export > Save for Web (Legacy) as GIF.

Option C: Use Free Desktop Software

• Tools like GIMP (free alternative to Photoshop) or ScreenToGif (Windows) let you import images and create animated GIFs.
• In GIMP: Import images as layers, use the Filters > Animation > Playback tool, then export as GIF.
• In ScreenToGif: Use the "Image Sequence" feature to import slides and adjust timing.

3. Optimize the GIF (Optional but Recommended)

Animated GIFs from PPTs can be large. To reduce file size:

• Resize images (eg, 800×600 instead of full PowerPoint resolution).
• Reduce the number of colors (256 is standard for GIFs).
• Increase frame delay or skip less important slides.
• Use tools like EZGIF's Compress feature or GIFski for smaller, high-quality output.

Basically, the process is:
Export slides → Convert to images → Assemble into GIF → Optimize.

It doesn't require advanced skills, and free tools make it accessible. Just keep the timing and file size in mind for smoother sharing.
