DivX to XviD Converter

DivX vs Xvid — Should You Even Convert?

Here is the honest answer most converter pages skip: DivX and Xvid are two implementations of the same codec — MPEG-4 Part 2, Advanced Simple Profile (ASP), usually wrapped in an AVI container with MP3 audio. Re-encoding from one to the other does not shrink the file, modernize it, or improve quality; it just re-compresses already-compressed video, which adds a generation of loss. The one legitimate reason to do it is a specific player, TV, or editing tool that insists on an Xvid-tagged AVI (the XVID FourCC) and chokes on a DivX-tagged one. If your real goal is a smaller, universally playable file, convert to MP4 (H.264) instead — that is a genuine upgrade, not a lateral move.

Side-by-side Comparison

Because both are ASP and "technically identical on the decoder side," any player that truly supports one almost always plays the other — the gap is about the FourCC label and certification logos, not the actual picture.

When to Pick Xvid

• A media player, smart TV, or hardware decoder rejects your file and specifically asks for an Xvid / XVID FourCC AVI.
• An older editing or authoring tool only ingests Xvid-tagged AVI files.
• You want a fully open-source, GPL-licensed codec with no proprietary DivX tagging.
• You are matching an existing batch of Xvid AVIs so every clip carries the same FourCC.

When to Stay on DivX (or Go to MP4 Instead)

• Your file already plays everywhere you need it to — re-encoding only costs you quality.
• Your target is a DivX-Certified standalone DVD/Blu-ray player that wants the DIVX/DX50 tag.
• You actually want a smaller, modern, phone- and web-friendly file — pick H.264 in MP4, not Xvid. See DivX to MP4 for that path.

How to Convert DivX to Xvid

1. Upload Your DivX File: Drag and drop your .divx or .avi file onto the page, or click "+ Add Files." You can queue several clips and convert them with one set of settings.
2. Set the Quality Preset: Open Advanced Options and choose a Quality Preset — "Very High (Recommended)" keeps the picture close to the source, since any ASP-to-ASP re-encode loses a little detail.
3. Adjust Resolution or Bitrate (Optional): Use Video Resolution (Preset Resolutions or Width x Height) and the bitrate controls only if you need to fit a size budget; leaving them at the original avoids extra quality loss.
4. Convert and Download: Click "Convert" to get an Xvid-tagged AVI. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark.

Frequently Asked Questions

Will converting DivX to Xvid improve quality or make the file smaller?

No. DivX and Xvid are both MPEG-4 Part 2 ASP, so this is a re-encode within the same codec family, not an upgrade. You cannot recover detail that the original DivX encode already discarded, and the second encode adds its own generation of loss. Expect roughly the same file size and slightly lower quality. The only reason to do it is compatibility with a tool that demands the Xvid FourCC.

Why does a player reject my DivX file but accept Xvid?

Both decode identically, so a true ASP decoder plays either. The usual cause is certification or FourCC matching: some standalone players are licensed as "DivX Certified" or "Xvid" and check the AVI's four-character codec tag (DIVX/DX50 vs XVID) before playing. Re-tagging the stream as Xvid by re-encoding can satisfy a player that only recognizes the XVID FourCC.

Should I convert to Xvid or to MP4 (H.264)?

If you only need the Xvid FourCC for one stubborn device, convert to Xvid. For everything else, convert to MP4 (H.264): it compresses far more efficiently than MPEG-4 Part 2, plays natively on phones, browsers, and modern TVs, and produces a smaller file at the same quality. MPEG-4 Part 2 offered little compression gain over MPEG-2, whereas H.264 is the modern baseline — try DivX to MP4 or Xvid to MP4.

Will the audio change when I convert DivX to Xvid?

The video stream is re-encoded to Xvid, and the audio is typically kept as MP3, which is the standard pairing inside an AVI for these codecs. Audio is not re-tagged in the same way the video FourCC is, so a player rejecting the file is almost always reacting to the video codec, not the soundtrack.

Do I need to install the DivX or Xvid codec to do this?

No. The conversion runs on our servers, so you do not install any codec, player, or desktop software. You only need the codec installed locally if you want to play the resulting Xvid AVI in a player that lacks built-in MPEG-4 Part 2 support — VLC, for example, plays both DivX and Xvid out of the box without any extra download.

Is my file private during conversion?

Yes. Your file is uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. There is no sign-up, no watermark, and files are never shared or made public. In our testing, a typical 700 MB DivX AVI re-encoded to Xvid at the "Very High" preset came out within a few percent of the original size — confirming the conversion is a lateral move, not a size reduction.
