How to Merge Zoom and Loom Recordings Into One Video Free

Zoom and Loom both produce multiple video files when a recording is paused, restarted, or split by session. If you want one continuous video from several recording segments, the free browser merger is the fastest solution: drop in all the MP4 files, drag to the right sequence, and download one combined video. No upload, no account, no file size cap.

This guide covers why Zoom and Loom produce split files, how to reconstruct a single recording, and the best workflow for common use cases like training content, client demos, and meeting replays.

Why Zoom Produces Multiple MP4 Files From One Meeting

Zoom's local recording creates a new MP4 file each time recording is paused and resumed. If you started recording, paused to handle a sensitive topic, resumed, then paused again, you end up with 2-3 separate files covering one meeting.

Cloud recordings on Zoom (paid plans) also sometimes split recordings for long meetings, producing "part 1," "part 2" files. The same is true when a meeting exceeds certain duration thresholds.

Common file naming from Zoom local recordings: zoom_0.mp4, zoom_1.mp4, zoom_2.mp4. Cloud recordings often include timestamps in the filename.

For a standalone meeting replay, training video, or client deliverable, you want one continuous file — not a folder of numbered clips that the viewer has to open manually in sequence.

Loom Recordings and When You Need to Merge Them

Loom saves each recording session as a separate video. If you recorded a walkthrough in three sessions (for example, recording Chapter 1, stopping, recording Chapter 2 the next day), you have three separate Loom videos that aren't automatically linked.

Loom also has a free plan recording length limit. If your original content exceeds the limit, you may have had to split it across multiple Loom recordings. Merging lets you create one final file to share or upload.

To download a Loom recording as MP4: open the Loom video, click the download button, and save the MP4 file. Do this for each recording segment, then merge them all at once.

Step-by-Step: Merge Multiple Zoom or Loom Recordings

1. Locate your recording files — Zoom local recordings are in Documents/Zoom/[Meeting Name]/ by default on Windows, and in ~/Documents/Zoom/ on Mac. Loom files need to be downloaded from the Loom web app.
2. Open the merger — Go to the free video merger. No account needed.
3. Add your files — Drag all recording MP4 files into the upload zone. They appear as numbered cards.
4. Check the order — Drag cards to arrange chronologically. For Zoom files named zoom_0, zoom_1, the default order is usually correct.
5. Merge — Click Merge Videos. A progress bar shows encoding status.
6. Download — The combined file downloads as a single MP4 when complete.

Meeting recordings tend to be large files (typically 500MB–3GB per hour at 1080p). The browser merger handles these without an upload cap since processing runs locally on your device.

What to Do After Merging Meeting Recordings

After combining your recording segments, you may want to:

• Trim the start and end — Remove the "getting started" setup time before the meeting began, or the "thanks everyone, see you next time" section at the end. Use the free trimmer on the merged file.
• Compress before sharing — A 2-hour meeting at 1080p can be 3-5GB. Compress for email or sharing to get it under 1GB without visible quality loss at standard playback size.
• Crop black bars — Zoom sometimes adds letterbox bars when screen shares of different aspect ratios appear mid-meeting. Use the crop tool to remove them.

Handling Confidential Zoom Recordings Privately

Meeting recordings often contain sensitive business content — client discussions, HR conversations, financial updates. Uploading them to a server-based tool creates a privacy risk: the service stores your video, at least temporarily, and their privacy policy governs what they can do with it.

The browser merger processes files entirely in your browser with no server upload. Your meeting recordings never leave your device. There are no terms of service to review, no data retention concerns, no account to link the files to. When the browser tab closes, the files are gone from the tool's scope entirely.

This is the same reason law firms, medical practices, and finance teams increasingly prefer browser-based file tools for sensitive documents. See also: merging on Mac and Windows for platform-specific notes.

Frequently Asked Questions

Where are Zoom local recordings stored on my computer?

Windows: Documents/Zoom/[Meeting Date]/. Mac: ~/Documents/Zoom/[Meeting Date]/. Each folder contains zoom_0.mp4, zoom_1.mp4 (if recording was paused), plus a vtt transcript file. You only need the .mp4 files for merging.

Can I merge a Zoom cloud recording with a local recording?

Yes, as long as you download both as MP4 files first. Download the cloud recording from the Zoom web portal, and locate your local recording file. Then drop both into the merger and combine them.

Can I merge Loom videos without downloading them?

No — the browser merger works with local files on your device. You need to download each Loom recording as an MP4 file first, then merge the downloaded files.

Does this tool work with Zoom cloud recording .mp4 files?

Yes. Zoom cloud recording MP4 files are standard H.264 files that the merger handles identically to local recordings. Download them from the Zoom web portal, then drop them into the merger.
