WebP to WMV Converter

How to Convert WebP to WMV Online

1. Upload Your WebP Files: Drag and drop one or more .webp files, or click "Add Files" to browse. Both still and animated WebP work; multiple stills become a slideshow in upload order.
2. Pick Merge Strategy and Duration: Set "Merge images" to combine all uploads into a single WMV slideshow, or "Video per image" to emit one WMV per file. Under "Image Duration", pick how long each frame holds — defaults to 5 seconds per frame; options run from 1/60 second up to 10 seconds for ken-burns style slideshows or quick stop-motion.
3. Adjust Background, Quality, and Resolution (Optional): Pick a Background Color (default Black) to letterbox images with mismatched aspect ratios. Under Quality Preset, pick Constant Quality (default Very High) or Constraint Quality to cap file size. Choose a Resolution Preset (480p, 720p, 1080p, 1440p, 4K) or keep original; width/height entries preserve aspect ratio by default.
4. Convert and Download: Click "Convert". Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared. Output is a standard .wmv (ASF container with WMV2 video) that plays natively in Windows Media Player.

Why Convert WebP to WMV?

WebP is Google's web image format — VP8-based lossy or VP8L lossless compression, alpha channel, and optional animation via ANIM/ANMF chunks (WebP container spec). WMV is Microsoft's video format: .wmv files are ASF containers carrying Windows Media Video (versions 7, 8, or 9) and Windows Media Audio streams. Going from WebP to WMV almost always means one of two jobs: turning a stack of still WebPs into a slideshow video, or wrapping an animated WebP in a format that Windows-only workflows can consume.

• Windows Media Player playback without codec packs — WMV plays natively in every Windows Media Player release on Windows 7, 8, 10, and 11. Animated WebP does not; even WMP 12 requires third-party codecs to render WebP at all, so converting to WMV is the lowest-friction way to share motion content with a Windows-first audience.
• Embedding in older PowerPoint and legacy CMS systems — PowerPoint 2010 and 2013 accept WMV as a first-class inline video format, while WebP support didn't land in Office until 2021. Corporate SharePoint and intranet portals built on legacy ASP.NET still default to WMV for HR videos, training decks, and product demos.
• Slideshow output from batch image exports — If you've exported a folder of WebPs from Lightroom Classic, Affinity Photo, or a screenshot pipeline, "Merge images" produces a single timed slideshow with consistent frame duration — no NLE required.
• Animated WebP archival as a video container — Animated WebPs are limited to 8-bit ARGB and roughly 4 GiB per file; converting to WMV (which uses the SMPTE 421M / VC-1 standardized codec since March 2006) gives you a sane keyframe interval and lets you trim, splice, or re-edit in any Windows-native video tool.
• Compatibility with screen recorders and broadcast tools — Camtasia, OBS legacy presets, and Windows Game DVR all import WMV without complaint. Drop the converted slideshow on a timeline as a B-roll without transcoding twice.
• Smaller payloads for email and intranet share — WMV2 at "Very High" quality on a 720p slideshow typically lands well under 25 MB for short clips, fitting Gmail's 25 MB attachment cap and Microsoft 365 Outlook's default 33 MB outbound limit without further compression.

Frequently Asked Questions

Will my animated WebP keep all its frames when converted to WMV?

Yes. The converter reads every frame from the WebP ANMF chunks and re-encodes them as WMV video frames. Inter-frame timing from the WebP is honored, so a 24 fps animated WebP becomes a 24 fps WMV. The one caveat: WebP supports an alpha channel, but WMV does not — transparent pixels are composited against the Background Color you choose (default Black) before encoding.

Why use WMV instead of MP4 for a Windows-only audience?

Native Windows Media Player playback. Microsoft's support page is explicit that "Windows Media Player does not support the playback of the.mp4 file format" out of the box; MP4 needs a DirectShow-compatible MPEG-4 decoder pack. WMV (and its ASF container) is a first-class WMP format on every Windows release since XP. For corporate environments locked to Windows Media Player or legacy PowerPoint embeds, WMV avoids the codec-pack problem entirely. For everywhere else, WebP to MP4 is the better default.

Can I add background music to the slideshow?

Not in this single-pass converter. The output WMV has a silent WMA audio track. To layer music in, convert to WMV first, then open the file in Windows Movie Maker (deprecated but still works on Windows 10), DaVinci Resolve, or Clipchamp and drop an MP3 onto the audio track. If you only need the music and not the WMV-specific delivery, convert WebP to MP4 and use any common NLE.

How many WebP files can I merge into one WMV slideshow?

There is no hard cap in the converter; the practical limit is upload size and connection speed. A 1080p slideshow at 5 seconds per frame produces roughly 2-4 MB per frame at "Very High" quality, so a 200-image slideshow comfortably lands in the 400-800 MB range. For larger batches, split into chapters and merge with a separate WMV joiner, or use convert image to video which has the same backend.

What WMV codec does the converter output?

WMV2 (Windows Media Video 9 Simple/Main Profile) in an ASF container — the most broadly compatible WMV variant, playable on Windows Media Player 9 and later without any codec installation. WMV9 was standardized as SMPTE 421M (VC-1) in March 2006, so the output is also playable in any modern player with VC-1 support, including VLC and most smart TVs.

Does WMV play on macOS, iPhone, or Android?

Not natively in 2026. macOS dropped first-party WMV support when Apple discontinued the Flip4Mac plugin; the practical fix on macOS and iOS is VLC. Android has no native WMV decoder either — VLC for Android handles it. If your audience is mixed-platform, convert to MP4 instead; if you need to round-trip a WMV you've already produced, convert WMV to MP4 handles that direction.

How do "Merge images" and "Video per image" differ?

"Merge images" combines every uploaded WebP into one slideshow WMV — frames render in upload order with your chosen Image Duration between transitions. "Video per image" emits a separate WMV per WebP, each one a single-frame loop at the duration you set. Use the second mode when you need per-image WMVs for individual product pages or to drop separate clips on a timeline later.

Will the converted WMV play in PowerPoint?

Yes, with one version note. PowerPoint 2010 and later embed .wmv natively (no codec install). PowerPoint 2007 needs the Microsoft Office codec pack. PowerPoint for Mac and PowerPoint for the Web do not play WMV — for cross-platform decks, use MP4. Keep slideshow resolution at 1280×720 or 1920×1080; mismatched aspect ratios get the Background Color letterbox bars you selected.

How does WebP to WMV compare to going through GIF?

WMV gives you real video codec compression, an audio track slot, and timeline-friendly metadata; WebP to GIF is limited to a 256-color palette and has no audio, but plays inline in email clients and Slack where WMV won't. Pick WMV for Windows Media Player and PowerPoint workflows, GIF for chat and forum embeds, and MP4 for everything else.
