Supports: WEBP
Animated WebP delivers great compression for web display — but it's an image format, not a video format. Most social media platforms, messaging apps, video editors, and TVs treat it as a still image (showing only the first frame) or reject it entirely. Converting WebP to MP4 (or another video container) restores playback everywhere:
.webp files. Converting them to MP4 lets you re-share on platforms that don't speak WebP, or archive a sticker collection as playable videos.| Property | Animated WebP | MP4 |
|---|---|---|
| Type | Animated image format | Video container |
| Created by | Google (2010) | ISO/IEC (MPEG-4 Part 14) |
| Compression | VP8 lossy + lossless modes | H.264, H.265, AV1, VP9 (codec-flexible) |
| Transparency / alpha | Yes | No (alpha replaced with background color) |
| Audio | None | Yes (AAC, MP3, Opus, etc.) |
| Native playback | Modern browsers, some image viewers | Every OS, browser, TV, phone, social platform |
| Editor support | Rare (rejected by Premiere, Final Cut, Resolve) | Universal |
| Typical use | Web banners, stickers, GIF replacements | Sharing, streaming, editing, archiving |
| Codec | File size (relative) | Compatibility | Best for |
|---|---|---|---|
| H.264 | 100% (baseline) | Every device made since 2010 | Default — works everywhere, social media uploads |
| H.265 / HEVC | ~60% | Modern devices (2017+), Apple ecosystem | Smaller files, AirDrop, iOS sharing |
| VP9 | ~70% | Browsers, YouTube, Android | Web embedding, royalty-free |
| AV1 | ~50% | 2022+ devices, modern browsers | Streaming, smallest size at high quality |
| MJPEG | ~250% | Universal but bulky | Frame-accurate editing intermediates |
Yes — every frame and the original frame timing of the animated WebP is read and re-encoded into the output video. A 24 fps sticker stays 24 fps. Because MP4 uses inter-frame compression (each frame references the previous one) while WebP encodes frames more independently, the file size is usually smaller after conversion at equivalent visual quality. Static (non-animated) WebP files become a single-frame video — set the Duration option to control how long that frame holds on screen.
MP4, MOV, AVI, and most video containers don't support alpha transparency, so transparent pixels need a fill color. XConvert lets you pick the Background Color (Black is default, White, Red, Green, Blue, and 20+ named options). For projects that need real transparency, export as WebM with VP9 (some editors and browsers support alpha) or keep the alpha by converting to an animated GIF with WebP to GIF.
Both platforms treat WebP as a still image regardless of whether it's animated. Instagram strips the animation on upload; TikTok rejects the file outright. Converting to MP4 (H.264, 1080p, under 60 seconds) hits Reels / TikTok specs exactly and uploads as a normal video.
H.264 if your audience could be on any device — older Windows laptops, work computers, smart TVs from before 2018, Chromecast 1st gen. H.265 if you want roughly 40% smaller files and you know the recipient is on iPhone, modern Android, macOS, recent Windows 11, or a 2018+ smart TV. For uploads to YouTube, Instagram, or TikTok, H.264 is safest because the platform re-encodes anyway and prefers a clean H.264 source.
Save the sticker (it downloads as .webp on Android, sometimes .tgs on iOS — only .webp works here), upload it, leave the codec on H.264 and quality on Highest, and download the MP4. The output plays in any video app and can be re-uploaded to Instagram Stories, TikTok, or shared via iMessage where Telegram stickers don't natively work.
XConvert handles large animated WebP files including long-form animations and high-resolution stickers. Conversion happens in your browser session, so the practical limit is your device's available memory rather than a fixed cap. There's no quantity limit on batch jobs.
Yes. Use the trim section to enter a start time and duration. Both accept seconds (2.5) or HH:MM:SS.sss format (00:00:02.500). Trim first to drop intro/outro frames and shrink the output before encoding. You can also use Drop Frames (1-in-2 through 1-in-10) to thin the frame rate for smaller files at the cost of smoother motion.
Yes — see MP4 to WebP for the reverse direction (useful for web banners and product images), or Video to WebP for any video container.
