What Video Formats and Size Limits Does Dubz.co Support?

Updated

Dubz.co accepts the most popular video formats, including MP4 and MOV, with a maximum file size of 100MB per video and no limit on video duration. You can upload as a guest without creating an account, and free-account videos are not deleted after 90 days as long as they keep getting views.

Supported Video Formats

According to Dubz.co's own site, the platform supports "the most popular formats like MP4 and MOV." Those two are the formats the site names explicitly, and they cover the vast majority of what people upload from phones, cameras, and screen recorders.

  • MP4 — the safest choice. It plays in every browser and on every social platform, so an MP4 upload is the least likely to run into playback or conversion problems.
  • MOV — the standard container for iPhone and Mac recordings. If you shot video on an Apple device and haven't converted it, MOV is the format you'll have.

If your file is in another container (for example MKV, AVI, or WebM), the site does not list it as supported. Converting to MP4 before uploading is the reliable workaround.

Upload Limits at a Glance

Limit Value
Max file size 100MB per video
Max duration Unlimited
Account required No — guest upload is available
Free-plan deletion No 90-day deletion while the video keeps getting views

The 100MB cap is the constraint most likely to affect you. Because duration is unlimited, a long but low-bitrate recording can fit under 100MB, while a short 4K clip can exceed it. If you're over the limit, the practical options are trimming the clip, lowering the resolution or bitrate before export, or splitting the video into parts.

What This Means for Different Uploads

  • Short social clips (X.com, Reddit, etc.): Almost always well under 100MB. MP4 is the format to use for the widest compatibility when sharing.
  • Phone recordings: MOV straight from an iPhone usually works, but a few minutes of 4K footage can pass 100MB quickly. Check the file size before uploading.
  • Screen recordings and tutorials: Often long but compressed, so they frequently fit despite the duration being unlimited. Export at 1080p rather than 4K to stay under the cap.
  • Long or high-resolution video: You'll likely need to compress or split the file first.

Editing Before or After Upload

Dubz.co also offers in-browser editing with no popups, ads, cookies, or watermarks. You can trim, crop, add stickers, text, and filters, and adjust colors. This matters for the size limit: trimming a clip in the browser is one way to cut a file down, and because the editing happens in your browser, you don't need to install anything.

Quick Checklist Before You Upload

  1. Confirm the file is MP4 or MOV.
  2. Check the file size is 100MB or less.
  3. If it's over, trim, compress, or split it first.
  4. Upload as a guest or log in, then share the link to X.com, Reddit, or elsewhere.

The two numbers to remember are simple: MP4 or MOV, and 100MB max — with no cap on how long the video runs.
