RMVB to DivX Converter

RMVB to DivX — and Whether DivX Is the Right Target

If you have old .rmvb downloads that nothing modern will play, converting out of RealMedia is the right call — almost nothing made after the mid-2000s reads RMVB without RealPlayer or VLC. DivX is a reasonable target only if you specifically need playback on an older DivX-certified standalone DVD/Blu-ray player. For everything else — phones, smart TVs, laptops, web — convert to MP4 (H.264) instead: it is smaller per frame, higher quality, and plays everywhere. This page does RMVB to DivX honestly, but read the comparison first.

RMVB vs DivX, Side by Side

When DivX Actually Makes Sense

• You own a DivX-certified or Xvid-certified standalone player (a 2005-2012 DVD/Blu-ray deck or media box) and want files it will read from a USB stick or burned disc.
• You are feeding an older device whose firmware lists "DivX" or "Xvid" but not "H.264/MP4".
• You are matching an existing library that is already DivX/Xvid AVI and want consistency.

DivX and Xvid are the same MPEG-4 ASP family, so a DivX file generally plays anywhere Xvid does and vice versa.

When to Convert to MP4 Instead

• You want playback on phones, tablets, smart TVs, browsers, or any device made in the last decade.
• You care about file size — H.264 fits the same quality into noticeably fewer bytes than MPEG-4 Part 2.
• You plan to edit, stream, or upload the result anywhere online.

For these, use RMVB to MP4. If you already have DivX files and now regret it, DivX to MP4 handles the second hop.

How to Convert RMVB to DivX

1. Upload Your RMVB File: Drag and drop your .rmvb file or click "Add Files." You can queue several at once and they convert with the same settings.
2. Set the Quality Preset: Under Advanced Options, leave Quality Preset on "Very High (Recommended)" to keep as much detail as the source has, or switch to Specific file size if you need the output to fit a USB stick or disc.
3. Adjust Resolution or Trim (Optional): Use Preset Resolutions or Width x Height to downscale for an older player, or the Trim / Time Range controls to export just a clip.
4. Convert and Download: Click "Convert" and download your DivX file. No sign-up, no watermark. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours.

Frequently Asked Questions

Will converting RMVB to DivX improve the video quality?

No. Re-encoding can never add detail that was not in the RMVB source. RMVB files were usually encoded at low bitrates for small downloads, so the best you can do is preserve what is there — choose "Very High" quality and avoid downscaling. Any conversion that targets a smaller file than the source will lose some quality.

Is DivX the same as Xvid?

Effectively yes for playback. Both are implementations of MPEG-4 Part 2 Advanced Simple Profile, so a DivX-encoded file plays on Xvid-capable players and vice versa. The main historical difference was the encoder and the "profile" restrictions DivX applied (the Home Theater profile drops features like Global Motion Compensation so older hardware decoders cope).

Why would I pick DivX over MP4 in 2026?

Only for old DivX/Xvid-certified standalone players. MP4 with H.264 is smaller, higher quality per byte, and plays on essentially every modern device, so for phones, TVs, and the web it is the better target. We list DivX because some legacy DVD and Blu-ray decks read DivX/Xvid AVI from USB but not MP4 — that is the one case it wins.

What plays an RMVB file natively, before I convert?

VLC and RealPlayer handle RMVB on Windows, macOS, and Linux; MPlayer and Totem work on Linux. Almost nothing else does — Windows Media Player, QuickTime, phones, and smart TVs generally will not, which is the reason most people convert RMVB out in the first place.

Does the DivX output keep the audio track?

Yes. The RealAudio (Cook) audio in your RMVB is re-encoded to MP3, which is the standard audio for DivX/AVI and is understood by every DivX-certified player. Subtitle tracks embedded in the RealMedia container are not carried into the DivX file; keep your separate .srt if you have one.

Are my files kept private?

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.
