WebP to XviD Converter

How to Convert WebP to Xvid Online

1. Upload Your WebP Files: Drag and drop, or click "+ Add Files" to select one or more .webp images. Both static (single-frame) and animated WebPs are accepted; upload multiple files to build a slideshow in upload order.
2. Pick Merge Strategy and Image Duration: Choose Merge images for a single slideshow AVI, or Video per image to get one Xvid AVI per WebP. Set Image Duration to 5 seconds per frame (default) or pick 1, 2, 3, 4, 6, 7, 8, 9, or 10 seconds — this controls how long each still is shown.
3. Set Background Color, Quality Preset, and Resolution (Optional): Background fills letterboxing when the WebP aspect ratio doesn't match output (default Black; 24 colors including White, Gray, Red, Blue). Under Quality Preset, switch between Constant Quality (target visual fidelity) and Constraint Quality (cap the bitrate); the preset dropdown ranges from Lowest to Highest, default Very High. For Video resolution, keep Original, pick a Fixed Resolution (1920x1080, 1280x720, 854x480, 640x360, etc.), or enter custom width/height.
4. Convert and Download: Click Convert. Files are processed in your browser session — no account, no watermark, no email required. Download the .avi (Xvid stream inside an AVI container) when each job finishes.

Why Convert WebP to Xvid?

WebP is a Google image format released in 2010 that supports both lossless (~26% smaller than PNG) and lossy compression (25-34% smaller than equivalent-quality JPEG), plus animated multi-frame sequences. Xvid is an open-source MPEG-4 Part 2 Advanced Simple Profile (ASP) encoder, first released in 2001 and licensed under GPL-2.0; its last stable release was version 1.3.7 in December 2019. Xvid streams are almost always wrapped in an AVI container, which is the format legacy DVD players and set-top boxes were built to read.

Converting WebP to Xvid AVI is fundamentally an image-to-video operation: each WebP frame (or each file in a batch) becomes a slide in a timed video. Common reasons to do this:

• Burning photos to a DVD-playable disc — Standalone DVD players from the mid-2000s onward almost universally support MPEG-4 ASP (DivX/Xvid) in AVI, while H.264/HEVC playback is hit-or-miss on the same hardware. An Xvid AVI slideshow plays in the living room without re-encoding.
• Legacy hardware and embedded systems — Older smart TVs, in-car head units, portable DVD players, and digital photo frames frequently list "DivX/Xvid AVI" in their spec sheet but not H.264. An Xvid file is the safest "will it play?" bet.
• Animated WebP to editable timeline — Animated WebPs cannot be dropped into most NLEs. Converting to Xvid AVI gives you a frame-by-frame video that Premiere, Resolve, Vegas, Shotcut, and Avidemux all decode natively via libavcodec.
• Batch slideshow generation — Drop 50 product photos, set 3 seconds each, and you get a single 150-second AVI ready for upload, kiosk display, or trade-show looping — no manual timeline assembly.
• Royalty-free encoding — Xvid is GPL-2.0; using it carries no MPEG LA H.264 patent-license obligations that apply to some commercial workflows.
• Long-term archival — MPEG-4 ASP is a mature 20+ year-old standard with stable decoder support across VLC, MPlayer, ffdshow, and any libavcodec-based player; the format isn't going anywhere.

WebP vs Xvid — Format Comparison

Quality Preset Quick Guide

The Quality Preset dropdown maps to internal quantizer / bitrate targets. Higher quality means larger file size.

For most slideshow use cases, Very High + Constant Quality at 1080p produces a clean AVI in the 2-6 MB-per-minute range. Drop to High or switch to Constraint Quality with a bitrate cap when targeting a fixed disc size (e.g., 4.38 GB single-layer DVD-R).

Frequently Asked Questions

Why convert a WebP to Xvid instead of MP4 (H.264)?

Compatibility with legacy playback hardware. DVD players, older smart TVs, in-car head units, and many digital photo frames support MPEG-4 ASP in AVI (the Xvid/DivX family) but not H.264. If you need a slideshow that will play on a 2008-era set-top box, Xvid is the safer choice. For modern devices, WebP to MP4 is a smaller, sharper option.

Will my animated WebP keep its motion when converted to Xvid?

Yes. Each frame of the animated WebP becomes a frame in the output Xvid AVI. The original WebP's frame timing is preserved as a single still per Image Duration setting — so if you want the AVI to play at the same speed as the source animation, choose the Image Duration that matches the WebP's frame delay (most animated WebPs use 1/10 second per frame, which is roughly equivalent to 10 fps).

What's the difference between Merge images and Video per image?

Merge images combines every uploaded WebP into one continuous AVI in upload order — useful for slideshows. Video per image produces one separate Xvid AVI per WebP — useful when each image needs to be its own clip (e.g., for editing them individually, or building a video-thumbnail set).

Is Xvid the same as DivX?

No, but they're closely related. Both are MPEG-4 Part 2 ASP encoders, so they produce compatible streams that any DivX or Xvid certified player can decode. The key difference: Xvid is open-source GPL-2.0 software developed by an independent project; DivX is proprietary, commercial software from DivX, LLC. A "DivX-certified" DVD player will almost always play Xvid AVIs without issue. See Xvid to DivX if you need the proprietary variant explicitly.

Can I add background music to the slideshow?

This converter outputs silent Xvid AVI (image-to-video with no audio track). If you need music, generate the AVI here, then merge it with an audio track in a free editor like Shotcut or Avidemux, or use a dedicated WebP to video workflow for richer authoring.

Why is the Xvid AVI so much larger than my WebP source?

WebP is highly optimized for still-image compression (one frame, intra-coded). Xvid AVI is a real video file with a frame for every Image Duration tick at your chosen frame rate, plus container overhead. A 200 KB WebP shown for 5 seconds at 1080p easily becomes a 1-3 MB AVI segment because the encoder is writing many frames of the same picture, not one. Lowering the Quality Preset to High or Medium, dropping the resolution to 720p, or reducing Image Duration all shrink the output.

Will the output play on Windows Media Player out of the box?

Modern Windows 10 and 11 ship with the necessary MPEG-4 ASP decoder for AVI playback in Media Player and the Movies & TV app. If a file refuses to play, install the K-Lite Codec Pack (which bundles ffdshow/libavcodec) or just use VLC, which decodes Xvid AVIs natively on every platform.

What's the maximum file or batch size?

There's no fixed cap published; processing happens in your browser session, so practical limits depend on your device's RAM and how long you're willing to wait. For very large batches (hundreds of high-resolution WebPs), split the upload into smaller groups to keep memory usage reasonable. If your source is animated WebP with thousands of frames, expect proportionally longer processing.

Can I convert WebP to other legacy video formats too?

Yes. Related conversions include WebP to AVI (lets you pick any AVI codec, not just Xvid), WebP to MP4 (modern H.264), WebP to MKV, and WebP to WMV for Windows-era hardware. For the reverse direction — extracting WebP stills from an Xvid AVI — see Xvid to WebP.
