DivX to AV1 Converter

Convert DivX to AV1 Online

DivX is an early-2000s MPEG-4 Part 2 codec — usually a .divx or .avi clip with MP3 audio — that was built to fit a movie on a CD. AV1 is the modern royalty-free AOMedia codec (finalized 2018) that compresses far harder. Converting DivX to AV1 shrinks an old clip and modernizes it for streaming and archival; it does not add detail the DivX source already discarded, so treat this as "smaller and more compatible," not "sharper."

How to Convert DivX to AV1

1. Upload Your DivX File: Drag and drop or click "Add Files" to add your .divx or .avi clips — old movie rips and camcorder footage all work. Batch is supported.
2. Pick a Quality Preset: The output is AV1 video with Opus audio at the "Very High (Recommended)" Preset. Instead of a preset you can target a Specific file size, set a Constant or Variable Bitrate, or use Constant Quality (CRF) to tune the size-vs-quality balance directly.
3. Resize or Trim (Optional): Under Video resolution choose Keep original, a Preset Resolution, a custom Width × Height, or a Resolution Percentage; use Trim → Time Range to keep only part of the clip. Old DivX is often only 640×480 or smaller, so leave the resolution alone rather than upscaling.
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.

DivX vs AV1 — Side-by-side Comparison

Frequently Asked Questions

Is AV1 better than DivX for my old clip?

For file size and future-proofing, yes — AV1 is a vastly more efficient, royalty-free codec, so the same footage stores in a fraction of the space and plays in current browsers. The catch is playback reach: a DivX/AVI file opens in VLC and most desktop players everywhere, while AV1 needs a recent player or device. If your only goal is to keep playing the clip on an old TV or DVD-era box, DivX is fine as-is; if you want it smaller and web-ready, AV1 wins.

Will converting DivX to AV1 improve the video quality?

No. AV1 only preserves the detail already present in the DivX source — it cannot recover what MPEG-4 Part 2 compression discarded. The benefit is a much smaller file at the same visual quality, not a sharper picture. If the DivX looks soft or blocky, that is baked into the source, and re-encoding keeps it the same (just smaller). There is no upscaling in a format conversion, so leave the resolution at Keep original.

How much smaller will the AV1 file be?

Usually a lot smaller. DivX is an early MPEG-4 codec with modest efficiency, so AV1 commonly produces a fraction of the size at comparable quality. In our testing, a 5-minute 640×480 DivX-in-AVI clip at the default Quality Preset re-encoded to an AV1 MP4 well under a third of the original size with no visible quality loss. The exact ratio depends on the source bitrate, resolution, and content — flat animation compresses better than grainy live action. Use Constant Quality (CRF) when you want to prioritize quality over a fixed size target.

Why is AV1 encoding so slow?

AV1 uses far more complex compression tools — large flexible block partitions, many prediction modes, and refined motion estimation — to squeeze out every bit of redundancy, and that analysis is CPU-intensive. AV1 encodes are often several times slower than legacy MPEG-4. For a one-off archive conversion the wait is usually worth the size savings; if you just need a quick, universally playable result, convert DivX to MP4 with H.264 encodes much faster and plays everywhere.

Can my devices actually play AV1?

Software playback is broad — VLC, MPV, and current Chrome, Firefox, and Edge all decode AV1, and Safari plays it on Apple Silicon with a hardware decoder (M3 Macs, iPhone 15 Pro and newer). Hardware decode is newer: Intel 11th-gen and Arc, NVIDIA RTX 30/40, AMD RDNA2+, and Snapdragon 8 Gen 2 all handle AV1 in hardware, and most TVs shipped since 2023 decode it at 4K. Older phones, TVs, and DVD-era players have no AV1 decoder at all — for those, convert to a widely supported format like DivX to MP4 instead.

Is AV1 really royalty-free, unlike DivX?

Yes. AV1 was created by the Alliance for Open Media (Google, Netflix, Amazon, Microsoft, Mozilla, Apple and others) to be royalty-free for any use, including commercial and paid streaming. DivX is a proprietary codec from DivX, LLC. That open licensing is a big reason streaming platforms adopted AV1, and it means an AV1 archive carries no patent-pool strings.
