AVIF to WMV Converter

Convert AVIF to WMV Online

This tool wraps an AVIF still image inside a WMV video — Microsoft's Windows Media Video format — by holding the picture as one motionless frame for a duration you choose. The result is a real .wmv file with no motion and no audio, built for the narrow case where an older Windows program, a legacy PowerPoint version, or a Windows Media Player-era device insists on Windows Media rather than a modern format. If you just want a video you can actually share, convert AVIF to MP4 instead — MP4 plays almost everywhere, while WMV plays poorly outside Windows. If you only need the picture, convert AVIF to JPG.

How to Convert AVIF to WMV

1. Upload Your AVIF File: Drag and drop your AVIF onto the page or click "+ Add Files". Add several images if you want them shown one after another in a single clip.
2. Choose Merge Strategy: Pick "Merge images" to combine every uploaded file into one WMV, or "Video per image" to get a separate WMV for each picture.
3. Set Image Duration and Background Color: "Image Duration" sets how long the frame is held (default "5 seconds per frame", up to 10); "Background Color" (default Black) fills any area the image does not cover after scaling.
4. Convert and Download: Click "Convert" and download your WMV. No sign-up, no watermark.

AVIF vs WMV at a Glance

Frequently Asked Questions

Does the WMV have any motion or sound?

No. A single AVIF is one frame, so the WMV shows that image held motionless for the duration you set, with no audio track — image-to-video conversions carry no sound, so the Audio Codec option is hidden. If you merge several images, you get a slideshow that cuts between them, but there is no movement within any frame.

Why convert an AVIF to WMV instead of MP4?

Only when something specifically requires Windows Media. WMV is built around Microsoft's ASF container and is meant for Windows Media Player and the Movies & TV app on Windows; it has no reliable native support on macOS, iPhone, or Android. For a clip you want to share, upload, or play on a phone or Mac, AVIF to MP4 is smaller and far more compatible — most people asking for WMV are better served by MP4.

What WMV codec does the output use?

By default the frame is encoded as WMV2, also called Windows Media Video 8, inside the ASF/.wmv container — the version the broadest range of Windows Media Player builds can open. The oldest players may need WMV1 (Windows Media Video 7), which you can select under Video Codec in Advanced Options at a cost of compression efficiency. WMV's later WMV 9 codec was standardized by SMPTE in March 2006 as SMPTE 421M, better known as VC-1.

Will the WMV keep AVIF's transparency or HDR?

No. AVIF can store an alpha channel and HDR, but WMV is an opaque video format, so any transparent regions are flattened onto the Background Color and the wide gamut is mapped down. If preserving transparency matters, keep the image as a still and convert AVIF to PNG instead — PNG keeps the alpha channel.

How large is the WMV, and is my file kept afterward?

In our testing, a single 1080p AVIF held for 5 seconds at the default "Very High" quality produces a small WMV — a few hundred kilobytes — because one repeated frame compresses efficiently; longer durations and higher resolutions grow it. Your AVIF is uploaded over an encrypted connection, converted on our servers, and deleted automatically a few hours after conversion. There is no sign-up, no watermark, and files are never shared or made public.
