XVID Converter

How to Convert XVID to Any Format

1. Upload Your XVID File: Drag and drop your video or click "Add Files". XVID footage almost always arrives as an .avi file, so the converter accepts those too — drop in several at once and each one converts in parallel.
2. Pick an Output Format and Quality Preset: Choose the target container — MP4, MOV, MKV, WebM, AVI, WMV, FLV, and 25+ more — or extract the audio to MP3. The default Quality Preset is "Very High (Recommended)". Switch to Specific file size to cap output at an exact MB target, Constant Bitrate for predictable sizes, Variable Bitrate for smaller files at equal quality, or Constant Quality to fine-tune by perceptual quality.
3. Resize, Trim, or Change Codec (Optional): Under Video resolution, keep original, pick a Preset Resolution (2160p / 1440p / 1080p / 720p / 480p / 360p / 240p), scale by Resolution Percentage, or enter a custom Width × Height. Under Trim, choose Time Range and enter start + duration. Advanced users can override the Video Codec (H.264, H.265, VP9, AV1, MPEG-4, MJPEG, XviD) and Audio Codec (AAC, MP3, Opus, FLAC, AC3, PCM).
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 an XVID File?

XVID (correctly spelled Xvid) is not a container at all — it's a codec. Xvid is an open-source implementation of the MPEG-4 Part 2 Advanced Simple Profile standard, maintained by volunteer developers and distributed under the GNU General Public License. It started in 2001 as a fork of OpenDivX after DivX Networks stopped publishing their open-source code, which is why people still describe Xvid as "the free DivX": both are MPEG-4 ASP codecs and both can usually read each other's files. The compressed video almost always lives inside an .avi (Audio Video Interleave) container, which is the file you actually downloaded or ripped years ago.

That legacy is exactly the problem. Xvid was excellent at squeezing a full-length movie onto a CD in the early 2000s, but it predates H.264 and the hardware-decode era. The reasons people convert away from it today:

• Playback on modern devices — Phones, browsers, smart TVs, and game consoles all decode H.264/AAC in MP4 in hardware, but most have no built-in Xvid support. Converting XVID to MP4 re-encodes the MPEG-4 ASP video to H.264 so the file plays everywhere without installing a codec pack or VLC.
• Editing software — Apple's Final Cut Pro and many modern NLEs reject raw Xvid-in-AVI or import it with audio-sync glitches. Re-wrapping to MOV or MP4 with H.264 gives editors a file that imports cleanly.
• Smaller, more efficient files — Xvid is roughly 40% less efficient than H.264 at equal quality, so re-encoding to H.264 (or H.265/AV1) usually produces a smaller file at the same visual quality — useful for storage, uploads, or messaging caps.
• Web and streaming delivery — AVI is not an HTML5 <video> format. Converting to MP4 (H.264) or WebM (VP9/AV1) is required before footage can stream in a browser.
• Audio extraction — Pulling the soundtrack out of an old clip is a remux-then-decode to MP3, which the converter handles directly.

Frequently Asked Questions

What opens an XVID or Xvid AVI file?

VLC Media Player and MPC-HC play Xvid-in-AVI out of the box on Windows, macOS, and Linux, because they bundle their own decoders. The trouble starts with default players: Windows Media Player, QuickTime, the iOS and Android built-in players, and browser <video> tags generally do not decode Xvid without an extra codec pack. That's why converting to MP4 (H.264) is the reliable fix — instead of installing software on every device, you change the file once so it plays natively everywhere.

Is converting XVID to MP4 lossy, and will I lose quality?

Re-encoding Xvid (MPEG-4 ASP) to H.264 is a true re-encode, not a remux, so it is technically lossy — but with a high-quality preset the loss is not visible in side-by-side viewing. In our testing, an old 700 MB Xvid AVI re-encoded to H.264 MP4 at the "Very High" preset came out visually indistinguishable from the source and slightly smaller, because H.264 is about 40% more efficient than Xvid at equal quality. If you want to avoid any new generational loss, the only fully lossless option is to re-wrap the Xvid stream into another AVI or MKV with XVID to MKV, which copies the video bytes unchanged.

What's the difference between Xvid and DivX?

Both are MPEG-4 Part 2 (ASP) codecs, so a player that handles one almost always handles the other, and their files are largely interchangeable. The difference is licensing and origin: DivX is a commercial product from DivX, Inc., while Xvid is open-source software released under the GPL — it began in 2001 as a community fork of the open-source OpenDivX code. In practice they compress to similar quality and size; the "free DivX" nickname for Xvid captures the relationship accurately.

Why does my Xvid AVI play but show no video (or no sound) on my phone?

This usually means the device decoded one stream but not the other. Many phones can play the MP3 audio inside an AVI but have no Xvid video decoder (you hear sound, see a black screen), or vice-versa. Rather than chase a codec pack, convert the file to MP4 with H.264 video and AAC audio — both are decoded in hardware on essentially every modern phone, so the picture and sound come back together.

Should I convert Xvid to H.265 or AV1 instead of H.264?

Only if you specifically need the smaller files and know the target supports them. H.264 is the safest choice because it plays on every device made since roughly 2010. H.265 (HEVC) and AV1 compress 40-50% smaller but have narrower hardware support — HEVC needs Safari 11+/recent Android, and AV1 decode needs Chrome 70+, Firefox 67+, or Safari 17+ and fairly recent GPUs. For a file you just want to play and share, stick with XVID to MP4; reserve H.265/AV1 for archives where storage savings matter more than universal playback.

Can I extract just the audio from an Xvid AVI?

Yes. Pick MP3 as the output format and the converter drops the Xvid video track and encodes the audio stream to MP3 — handy for pulling a song or a lecture's audio out of an old clip. The dedicated XVID to MP3 page walks through bitrate selection if you want to control the output size.

Are my uploaded files private?

Yes. Files are uploaded over an encrypted (TLS) connection, processed on our servers, and deleted automatically after a few hours — there's no sign-up, no watermark, and your files are never shared or made public. The practical limit on a very large AVI is upload time over your connection, not any per-file cap; for multi-gigabyte archives, expect the upload itself to take the most time.
