Supports: JPG, JPEG, JFIF
MOV is Apple's QuickTime container, defined by Apple as the on-disk wrapper for video, audio, timecode, and subtitle tracks. Turning a stack of JPGs into a MOV gives you a real video file you can scrub, edit, share, and embed — instead of a folder of stills your audience has to click through. Because most cameras and phones save JPG (or its modern sibling HEIC) as the default photo format, JPG → MOV is the shortest path from a shoot to a deliverable on Apple-centric editing pipelines.
| Property | JPG | MOV |
|---|---|---|
| Media type | Still image (raster) | Video container (QuickTime) |
| Compression | Lossy DCT, 8-bit | Depends on codec inside (H.264, H.265, ProRes, MJPEG) |
| Audio | None | Yes — silent unless you add an audio track later |
| Color | Up to 24-bit RGB, no alpha | Up to 10-bit with HEVC / ProRes, no alpha in H.264 |
| Native on macOS / iOS | Yes (Preview, Photos) | Yes (QuickTime Player, Photos, Final Cut) |
| Native on Windows | Yes (Photos) | H.264 MOV plays in Windows 11; HEVC needs the paid HEVC Video Extension from Microsoft Store |
| Best for | Storing one frame | Playing many frames in sequence with controlled timing |
Pick the codec that matches your delivery target, not the highest bitrate available:
| Codec | Quality vs size | Compatibility | Best slideshow use |
|---|---|---|---|
| H.264 (AVC) | Good — universally supported | Plays on every modern browser, phone, smart TV, Windows 11 natively | General sharing, web embed, social uploads |
| H.265 (HEVC) | Better — ~50% smaller at equal quality vs H.264 | Native on macOS, iOS 11+, Safari; Windows 11 needs the HEVC Video Extension | 4K / 8K slideshows, modern Apple-only audiences |
| MJPEG | Lower compression, each frame a JPEG | Universally decodable, easy to scrub | Editing intermediate where you'll re-encode later |
| MPEG-4 / Xvid / DivX | Legacy | Older players, DVD pipelines | Compatibility with older hardware only |
MOV and MP4 are very similar containers — both descend from Apple's QuickTime File Format — but MOV is the Apple-preferred wrapper. Final Cut Pro, iMovie, QuickTime Player, and ProRes-based workflows all expect MOV. If your audience is on Windows or Android, JPG to MP4 is the safer default; if your audience is editors on macOS, MOV is the cleaner ingest.
Apple's QuickTime Player slideshow guide recommends 2 to 3 seconds per frame for natural pacing. Use 1/24 or 1/30 second for time-lapse sequences (matches the 24fps / 30fps standards), 5 seconds for hero or product shots, and 8–10 seconds for slow contemplative reels. The Image Duration dropdown exposes all of these directly.
Set Video Resolution to a fixed preset (e.g. 1920×1080) or a custom Width × Height. Images that don't match the aspect ratio are letterboxed with the Background Color you picked, which is why the picker defaults to Black — it matches the cinematic letterbox most viewers expect.
The browser converter produces a silent MOV because mixing arbitrary audio in-browser is unreliable. Drop the MOV into iMovie, Final Cut Pro, DaVinci Resolve, or even QuickTime Player's edit mode and add the track there — MOV's container is designed for separate video and audio tracks, so adding audio later doesn't require a re-encode of the video.
H.264 is the safe default; it plays everywhere including older Windows machines. H.265 (HEVC) cuts file size roughly in half at equivalent visual quality but Windows 11 still requires Microsoft's paid HEVC Video Extension to play it natively. MJPEG keeps each frame as a JPEG inside the container, which is bulky but very easy to scrub through and re-edit. Pick H.264 unless you have a specific reason not to.
Yes — the input list order maps one-to-one to slideshow order. Rename your files numerically (shot-001.jpg, shot-002.jpg) before uploading if you care about a precise sequence; most operating systems sort by filename when you select-all-and-drag.
Quality Preset is a fixed-ladder choice (Very Low → Very High) — easiest if you don't speak codec. Constant Quality (CRF) lets you set a single rate-factor number (lower = better quality, larger file; typical range 18–28 for H.264). Constraint Quality (target bitrate) is for delivery targets where the platform caps bitrate, like Vimeo or a corporate LMS.
If you exported with the H.264 codec, yes — Windows 11's built-in Media Player handles H.264 MOV natively. If you exported with HEVC, Windows 11 users need Microsoft's HEVC Video Extension from the Microsoft Store (paid). When in doubt for cross-platform delivery, pick H.264 here or convert later with MOV to MP4.
JPG and JPEG are the same format — different file extensions for the same JPEG/JFIF data. This page accepts .jpg, .jpeg, and .jfif interchangeably; the JPEG to MOV page is an alias that produces identical output. If your source files are PNG instead, use PNG to MOV to preserve their alpha channel as a flat black-matte background.
