WebP to MP4 Converter

How to Convert WebP to MP4 Online

1. Upload Your WebP File: Drag and drop or click "Add Files" to select animated WebP files (stickers, memes, social-media clips) or static WebP images. Batch conversion is supported — drop in multiple WebP files and merge them into one MP4 if needed.
2. Pick a Video Codec and Quality: Default is H.264 — the codec every browser, phone, and social platform accepts. Choose H.265 / HEVC for ~40% smaller files at the same quality, VP9 for YouTube/web embedding, or AV1 for the smallest output on modern devices. Set a Video Quality Preset (Highest → Lowest) or fine-tune CRF via Constant Quality (18 = visually lossless, 23 = default, 28 = compact) — file-size and bitrate targeting modes don't appear for image sources, so shrink the output with a lower preset, a higher CRF, or a smaller resolution.
3. Set Frame Duration, Background Color, and Resolution (Optional): Animated WebP converts directly — every frame is carried over and the source's own frame timing is kept, so the Image Duration control has no effect on it. Image Duration applies to static images: pick how long each one is held (1/60s up to 10s) when building a slideshow from still WebP files. The Video Background Color option (white, black, or any of 25 named colors) is the color transparent WebP pixels are composited onto during encoding — MP4 has no alpha channel — and the same color fills letterbox bars when the output resolution's shape differs from your image. Pick a Video Resolution Preset (2160p / 1440p / 1080p / 720p / 480p / 360p / 240p / 144p), enter custom width × height, or scale by percentage.
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 WebP to MP4?

Animated WebP is Google's modern replacement for GIF — smaller files, better quality, transparency support — but most platforms and editors still don't accept it. Twitter/X, Instagram, TikTok, WhatsApp, Discord, iMessage, and every NLE editor (Premiere, DaVinci Resolve, CapCut, Final Cut) want MP4. Static WebP is also commonly stitched into MP4 slideshows for product videos and social posts.

• Animated stickers and memes for social media — Discord, Telegram, and Signal animated stickers ship as WebP. Re-uploading them to Instagram Reels, TikTok, X, or Facebook fails — those platforms reject animated WebP. Convert them to video via WebP → GIF → GIF → MP4 so every frame survives, and they upload in one click.
• Editing in Premiere, DaVinci, or CapCut — Consumer and pro NLEs don't import animated WebP. MP4 (H.264) drops straight onto the timeline with audio, frame-accurate trimming, and effects.
• iMessage and email sharing — iOS shows animated WebP as a static frame in iMessage and Mail. MP4 plays inline with autoplay, and stays under Gmail's 25 MB cap and iMessage's 100 MB cap when encoded with H.265.
• Embedding on websites and apps — Older Safari versions, Microsoft Outlook, and many CMS image fields choke on animated WebP. <video> tag with MP4 source plays everywhere since 2010 and supports lazy-loading.
• Slideshow videos from WebP photos — Stitch a folder of static WebP product shots, screenshots, or photo exports into a single MP4 with per-image duration and a background fill — ideal for Etsy/Shopify product videos or YouTube shorts.
• Archiving and re-encoding — WebP support across desktop video players is patchy (VLC handles it, QuickTime doesn't). MP4 is the safe long-term archival container.

Frequently Asked Questions

Why doesn't Instagram or TikTok accept my animated WebP directly?

Instagram, TikTok, X, Facebook Reels, and most social platforms only accept video containers (MP4, MOV, WebM in some cases) — not animated image formats like WebP, GIF, or APNG. Their upload pipelines transcode to H.264 internally and reject anything that isn't already a video stream. Converting to MP4 with H.264 codec at 1080p resolves uploads in one step, with no quality loss visible at typical viewing sizes.

My animated WebP has a transparent background — what happens when I convert?

MP4 has no alpha channel, so the transparency is flattened — transparent pixels are composited onto the Background Color option, white by default. If you want the backdrop to match where the sticker will be displayed (white or dark theme), pick that color from the dropdown; semi-transparent edges blend smoothly into it. No video output here preserves alpha (WebM included), so if the file must stay transparent, keep it as WebP.

Will the animation timing stay the same after converting?

Yes. Animated WebP is detected as animated and every frame is converted, with the source's frame timing preserved — a four-frame WebP holding each frame for 250 ms produces a one-second MP4 at 4 fps. Because the animation carries its own timing, the Image Duration control is ignored for animated sources; it only applies to static images. There is no need to route through GIF first, and doing so would cost quality, since GIF is limited to 256 colours and stores timing in centisecond steps.

Can I stitch multiple WebP images into one MP4 slideshow?

Yes. Upload several static WebP images, set the per-image duration (anywhere from 1/60 of a second up to 10 seconds), and XConvert merges them into a single MP4. Useful for product video reels, photo montages, and screen-recording stitches. If any source WebPs use transparency, those areas are composited onto the chosen Background Color in the video output.

Should I pick H.264 or H.265 for animated WebP conversions?

H.264 for maximum compatibility — works everywhere including older laptops, smart TVs, and corporate Outlook clients. H.265 if your animated WebP is short (sticker/meme length) and you want the smallest file for iMessage / WhatsApp sharing on Apple/Android devices made since 2018. Most animated WebPs are tiny (under 2 MB), so H.264 at default CRF is the simpler choice.

Why is my MP4 larger than the source WebP?

WebP uses a still-image codec (VP8 / VP8L) that compresses each frame independently with very high efficiency for small, low-motion clips. MP4's H.264/H.265 codecs add container overhead, audio track allocation (even when silent), and key-frame metadata. For a short sticker-length clip converted via the GIF route, the MP4 may be 2-4× the WebP size — but that's still measured in low double-digit kilobytes. Drop the CRF to 28 or use H.265 to close the gap.

Can I convert MP4 back to animated WebP?

Yes — see MP4 to WebP for the reverse direction (handy for shrinking short loops down for sticker packs and web embeds).

What's the file size limit?

XConvert handles WebP files of any size including multi-frame animations and long photo slideshows. Conversion runs on our servers, so the practical limit is upload size and connection speed on our servers cap. There is no fixed file count limit on batch jobs.

Does XConvert keep my files?

No. WebP and MP4 files are processed on our servers and deleted automatically after a few hours — no third-party storage, no email signup, no account, no watermark.
