JPG to WMV Converter

How to Convert JPG to WMV Online

1. Upload Your JPG Files: Drag and drop or click "Add Files" to select JPG, JPEG, or JFIF images. Multiple uploads are queued in order and become the slideshow sequence; reorder before converting if needed.
2. Pick Merge Strategy and Duration: Default is Merge images (one WMV containing every photo). Choose Video per image to output a separate WMV per JPG. Set Duration per frame from 1/60 second up to 10 seconds — 3 to 5 seconds is typical for a photo slideshow, 1/24 to 1/30 second for stop-motion.
3. Set Resolution, Background, and Quality (Optional): Pick a Preset Resolution (1080p, 720p, 480p) or set custom Width/Height with Keep aspect ratio. Background Color (default Black) letterboxes JPGs that don't match the output aspect ratio. Under File Compression choose a Quality Preset (Very High through Lowest), Target file size, Constant Bitrate, or Constant Quality (CRF).
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.

Why Convert JPG to WMV?

WMV (Windows Media Video) is Microsoft's video format introduced in 1999, with WMV 9 standardized by SMPTE in 2006 as VC-1 — the same codec adopted by Blu-ray and HD DVD. The WMV container is ASF (Advanced Systems Format). Turning a JPG sequence into a single WMV gives you one playable video file instead of a folder of photos, which is what most Windows-era media servers, kiosks, and PowerPoint decks expect.

• Slideshows for legacy Windows playback — WMV plays natively in Windows Media Player Legacy and the new Media Player app on Windows 10 and 11 with no codec install. Useful when the destination machine is locked down and can't install VLC.
• PowerPoint on pre-2505 versions — Older PowerPoint builds embed WMV directly; PowerPoint version 2505 and later still accept it but mark WMV support as deprecated and transcode to MP4 on insert.
• Digital signage and kiosks running Windows — Many sign player apps (Xibo, Rise Vision Windows Player, older ScreenScape) prefer WMV for low-overhead decoding on Atom-class hardware.
• Stop-motion and time-lapse builds — Setting Duration to 1/24 or 1/30 second turns numbered JPGs (frame_0001.jpg, frame_0002.jpg, …) into a continuous animation at 24 or 30 fps.
• Sharing photo compilations inside Windows-only environments — Corporate intranets and SharePoint sites historically standardized on WMV/ASF; converting JPG batches keeps everything on the approved codec list.
• Archival of photo timelines — Wrapping a year of JPGs into one WMV with a 3-second-per-frame cadence creates a watchable retrospective at a fraction of the disk footprint of the source folder.

Frequently Asked Questions

Why pick WMV instead of MP4 for a JPG slideshow?

Pick WMV only when the playback target is locked to Windows tooling that expects ASF: an older PowerPoint deck, a Windows-based digital sign, a corporate SharePoint policy that whitelists.wmv, or a vintage Windows Media Player kiosk. For anything modern — phones, browsers, Macs, smart TVs, YouTube — use JPG to MP4 instead. MP4 with H.264 plays natively on iOS, Android, macOS, every browser, and every smart TV from the last decade.

Will my WMV slideshow play on a Mac?

Not natively. macOS dropped WMV support when Microsoft retired Flip4Mac. The reliable option on Mac is VLC, which decodes WMV/VC-1 in software. Microsoft PowerPoint for Mac explicitly does not support.wmv or.wma — Microsoft's own documentation flags this. If a Mac viewer is in the audience, convert to JPG to MOV or MP4 instead.

What codec does my WMV use?

The default is WMV2 (Windows Media Video 8) inside an ASF container, with WMA v2 for the audio track if present. WMV2 is the codec Windows Media Player has shipped with since Windows XP, so playback works without any codec pack install. Under Video Codec you can also pick H.264 wrapped in ASF if your target player accepts it — quality per bit is higher, but you trade some of the "works on every Windows box without prompts" guarantee.

How do I turn a folder of frame_0001.jpg, frame_0002.jpg into a stop-motion video?

Upload the JPGs in order (most browsers preserve filename order on multi-select), keep Merge Strategy on Merge images, and set Duration to 1/24 second for cinema cadence, 1/30 for video cadence, or 1/60 for high-speed playback. Each JPG becomes one frame. A 240-frame sequence at 1/24 second yields a 10-second clip; at 1/30 it yields 8 seconds.

My JPGs are different sizes — what happens at the edges?

The converter scales each JPG to fit the chosen output resolution while preserving aspect ratio, then fills the empty bars with the Background Color you picked (Black by default; 20+ named colors plus custom hex are available). If you want zero letterboxing, set output Width/Height to match the dominant JPG aspect ratio, or pre-crop the outliers with Crop JPG.

Can I add background music to the slideshow?

The JPG-to-WMV step itself produces a silent WMV (or a WMA-v2 silent track if the codec requires one). To add music, run the WMV through a video editor that supports audio overlay, or convert your photo set to MP4 first, then merge with an audio track. WMV's ASF container does carry WMA audio if you bring your own — the converter just doesn't generate music for you.

What's a reasonable bitrate or file size for a 30-photo slideshow at 1080p?

At 5 seconds per frame, 30 photos is a 150-second WMV. At the default Very High Quality Preset and WMV2 codec, expect roughly 4-8 Mbps, so 75-150 MB output. Drop to the Medium preset (~2 Mbps) for a ~40 MB file suitable for email or chat. Use Target file size if you need a hard cap — the encoder picks the bitrate to land near your number.

Does WMV still make sense in 2026, or is it obsolete?

WMV is legacy but not dead. Windows 10 and 11 both ship Media Player apps that decode WMV/VC-1 out of the box, and the codec is still embedded in Blu-ray and HD DVD spec (VC-1). What's changing: PowerPoint version 2505 and later mark.wmv ingestion as deprecated, and Microsoft is steering everything new toward H.264/H.265 in MP4. Use WMV when a downstream Windows tool actually requires it; otherwise default to MP4. If you already have WMV files and need to modernize them, WMV to MP4 is a one-step transcode.

Is there a file size or count limit?

There's no hard file-count cap on the upload side, but very large batches are limited by your upload size and connection speed, since files are uploaded and converted on our servers. Split very large slideshows into chunks of 100-150 JPGs, render each as a WMV segment, and concatenate downstream if needed.
