VirtualDub ready
AVI is the native format of VirtualDub and legacy Windows video editing tools.
H.264 in AVI

100% private
Conversion happens in your browser. Your GIFs never leave your device.
How it works
Three steps, no hassle
Upload your animated GIF
Drag or select your animated .gif file. Memes, web animations, stickers, or any multi-frame GIF. No signup.
Convert to AVI
GIF frames are rendered and encoded as AVI video with H.264. You get a video with the same animation, compatible with players that can't read GIF.
Download your AVI
AVI file ready to embed in PowerPoint, use in VirtualDub, legacy Windows players, or any application that needs video instead of GIF.

AVI (Audio Video Interleave) is Microsoft's legacy video format, introduced in November 1992 with Windows 3.1 and Video for Windows. AVI is preferable to MP4 in specific cases: PowerPoint 2007 and earlier only accept AVI and WMV for embedded video (not MP4); VirtualDub, Avery Lee's open-source video editor (version 1.0 in 1998), works natively with AVI; some legacy surveillance systems and corporate kiosks only play AVI; and certain DVD players and corporate presentation systems accept AVI but not MP4. If your target is a modern system, MP4 would be more efficient, but AVI remains necessary for specific legacy workflows.
GIF (Graphics Interchange Format) was developed by CompuServe in 1987 and uses 8-bit LZW compression per frame: each frame is an indexed image with up to 256 colors. Animation in GIF is a sequence of frames with individual delays in hundredths of a second. AVI is a Microsoft container encapsulating encoded video streams (Cinepak, DivX, H.264, etc.) with inter-frame compression. GIF has no inter-frame compression: each frame is compressed independently. AVI with H.264 has temporal compression (I-frames, P-frames, B-frames), resulting in much smaller files than the equivalent GIF for longer animations.
Yes. PowerPoint 2007, 2010, and 2013 have native support for AVI with codecs including H.264, DivX, Xvid, and Cinepak. The generated AVI uses H.264, which PowerPoint 2010+ plays without installing additional codecs on Windows 7+ with Microsoft platform codecs. For PowerPoint 2007 on Windows XP, third-party H.264 codecs may be needed. For PowerPoint 2016+ or Microsoft 365, using MP4 directly is recommended for better support.
Yes. VirtualDub (current version VirtualDub2, fork maintained by shekh-ali) works natively with AVI and can open, filter, and re-encode AVI files generated from GIF. The typical workflow is: convert GIF to AVI (getting the video without audio), open in VirtualDub to apply filters (resize, color adjust, add effects), and save the final result as AVI or convert to another format from VirtualDub. For memes used in video editing, this pipeline lets you manipulate the GIF with full video editing tools.
GIF supports 1-bit transparency per frame: one color from the 256-color palette is designated as transparent. When converting to AVI, transparent areas are filled with black or white background (configurable). AVI with H.264 Main or High profile doesn't support alpha channel (transparency), so transparency cannot be preserved in standard AVI. If you need transparency in video, the correct format would be WebM with VP9 or MOV with ProRes 4444 codec.
Animated GIFs have variable per-frame delays expressed in hundredths of a second in the Graphic Control Extension block. A GIF with 10cs/frame delays has 10 fps; one with 4cs/frame has 25 fps. When converting to AVI, GIF delays are respected by creating the AVI at the original GIF's frame rate. If delays are variable (some GIFs have frames with different durations), FFmpeg uses the GCD (greatest common divisor) of all delays to determine the AVI frame rate, duplicating frames as needed to maintain correct timing.
Convert GIF to AVI: from web animation to compatible legacy video
GIF (Graphics Interchange Format) was developed by CompuServe in May 1987 by a team led by Bob Berry, and the animation extension (GIF89a) was published in July 1989. Despite being over 35 years old, GIF remains the dominant format for short animations on social media, messaging platforms, and web communications. The fundamental technical limitation of GIF is its 256-color palette per frame (a legacy of 8-bit display hardware) and the absence of inter-frame compression: each frame is compressed independently with LZW, making animated GIFs notably larger than equivalent video. A 10-second GIF at 15 fps can weigh between 5 and 20 MB, while the same content in H.264 MP4 would occupy less than 500 KB. AVI (Audio Video Interleave) was introduced by Microsoft in November 1992 as part of Video for Windows and was the standard Windows video format for over a decade, gradually replaced by WMV and then MP4. However, AVI maintains relevance in specific workflows where its compatibility with legacy software is irreplaceable.
Converting GIF to AVI has concrete use cases in corporate and creative environments. Microsoft PowerPoint 2007 and 2010 do not play animated GIFs in presentations: the GIF image displays as a static first frame. The solution documented in Microsoft's knowledge base is to insert animated content as AVI or WMV video. Many corporate training and marketing departments have PowerPoint presentations that need to show animations (interface mockups, product demos, moving data) and the only format compatible with legacy Office versions is AVI. VirtualDub, the open-source video editor created by Avery Lee (first public version in 1998, based on Windows AVI/VFW format), is another application that requires AVI as input for filtering and processing video. The YouTube video editing community used VirtualDub extensively between 2006 and 2015 before DaVinci Resolve and Premiere became popular. For memes and animations that need processing in legacy tools, GIF to AVI is the necessary pipeline.
Convertir.ai executes the GIF to AVI conversion in the browser using FFmpeg.wasm. The technical process involves several steps: first, FFmpeg decodes the GIF frame by frame using libavcodec's gif decoder, interpreting the Graphic Control Extension delays for each frame (values in hundredths of a second, with the special value 0 interpreted as 100ms per the GIF89a specification). Each frame's 256-color palette is converted to YUV 4:2:0 color space for H.264 encoding. GIF transparency (a single color designated as transparent in the palette via the Transparent Color Flag in the GCE) is converted to black or white pixels depending on the configured background. H.264 encoding in the AVI container is performed with libx264 at CRF 18 by default, resulting in an AVI file significantly smaller than the original GIF for animations longer than 3 seconds. The generated AVI container is compatible with Windows DirectShow (the Windows XP+ video playback system), VirtualDub, Media Player Classic, and PowerPoint 2007+. For short animations of 1–3 seconds, the AVI size may be similar to the original GIF due to container overhead and H.264's lower efficiency on very short sequences.
