Supports: WEBP
WebP is Google's image format (announced 30 September 2010, with animation support added 3 October 2011) that supports both still frames and short looping animations using VP8/VP8L compression inside a RIFF container. MOV is Apple's QuickTime container, first released publicly in 1991, which the ISO later adopted as the basis of MP4 (ISO/IEC 14496-14). Converting WebP to MOV means decoding the WebP frame data and re-encoding it as a true video stream that Apple's ecosystem treats as a first-class asset.
| Property | WebP (animated) | MOV |
|---|---|---|
| Owner | Google (2010) | Apple (1991) |
| Container | RIFF | QuickTime atom tree |
| Compression | VP8 / VP8L | Codec-dependent (H.264, H.265, ProRes, MJPEG, etc.) |
| Max dimension | 16,383 px per side | Codec-limited (H.264 ≤ 4096 px Level 5.1; H.265 to 8K) |
| Color depth | 8-bit YUV 4:2:0 (lossy) / 8-bit RGBA (lossless) | Up to 12-bit (ProRes), 10-bit HEVC, 8-bit H.264 |
| Audio | None | Multichannel (PCM, AAC, ALAC) |
| Transparency | Yes (alpha channel) | ProRes 4444 only; not in H.264/H.265 |
| Timeline editing | Frame-locked playback | Frame-accurate cut/trim/scrub |
| Native Apple support | macOS 11+ / iOS 14+ | All Apple OS versions |
| Pick | When to use | Notes |
|---|---|---|
| H.264 / Very High preset | Default for sharing, iMovie import, AirDrop | Works on every Apple device since 2009; ~2-4 MB per second at 1080p |
| H.265 / HEVC | macOS 10.13 High Sierra+, iOS 11+, smaller files | ~40-50% smaller than H.264 at equal quality; older Macs won't play |
| Constant Quality (CRF-style) | Predictable visual quality, variable file size | Lower number = higher quality; good for archival masters |
| Constraint Quality + preset | Predictable file size, variable quality | Use when uploading to size-capped platforms |
| MJPEG | Frame-by-frame editing or every-frame-is-a-keyframe needs | Larger files; widely supported in NLE software |
Yes — the converter decodes every frame from the animated WebP (the chunked VP8L/VP8 frame sequence inside the RIFF container) and stacks them as a video stream. If your animated WebP has 60 frames and you set a 1/30-second Duration, the output MOV is a 2-second clip. Frame ordering and disposal hints are preserved.
H.264 and H.265 MOV outputs do not carry an alpha channel, so transparent pixels are filled with the Background Color you select (Black by default; you can change it). If you need true transparency in MOV, you'd need a ProRes 4444 export — outside the scope of most online tools. For an alpha-preserving alternative, consider exporting to PNG sequence or to WebM/VP9 with alpha first.
Pick H.264 if the MOV will be shared widely or opened on older Macs (pre-2017) or older iPhones (pre-iPhone 7). Pick H.265 if you control the destination and want roughly 40-50% smaller files at the same visual quality. H.265 has been hardware-decoded on Apple devices since 2017 (iPhone 7 and macOS High Sierra 10.13).
Animated WebP uses VP8/VP8L which can compress redundant frames more aggressively than the codec inside MOV (especially H.264 at high quality). It's normal for a 500 KB animated WebP to become a 3-5 MB MOV at 1080p H.264. To shrink the output, lower the resolution, drop the quality preset from Very High to High or Medium, or switch the codec to H.265.
Frame rate in this tool is controlled by the Duration field — it sets how long each WebP frame displays. A Duration of 1/30 second yields a 30 fps video; 1/24 second yields 24 fps (cinema standard); 1/60 second yields 60 fps. If you have an animated WebP that was recorded at 15 fps and you want smoother motion, pick a shorter Duration but be aware no new motion data is invented.
Yes. A single static WebP becomes a still-image video — your selected Duration becomes the clip length (5 seconds default). Use "Merge images" with multiple static WebPs to build a slideshow MOV. Each image holds for the Duration you set.
Most Windows installations need either QuickTime, VLC, or recent versions of Windows Media Player to play MOV. Android playback varies — many devices play H.264 MOV files via Google Photos or VLC, but H.265 MOV may not decode in hardware on older devices. If cross-platform playback matters more than the.mov extension, see WebP to MP4, which uses the same codec but a more universally-recognized container.
Yes. Files are uploaded over an encrypted connection, processed on xconvert's servers, and deleted automatically after a few hours — no account or sign-up is created.
For looping animations meant for chat, Slack, or web embeds, GIF is often a better fit than MOV. See WebP to GIF for that workflow, or GIF to MOV if you have a GIF and need the MOV container for Final Cut Pro. To trim or compress an existing MOV, try compress MOV or MOV to MP4.
