Editing a video with sound can be quick and simple. There is no need to install any software first. Clideo lets you combine video and audio directly in your browser. You can upload music, narration, or another audio file easily. This guide shows the complete process until your video is ready.
What Clideo’s Add Audio to Video Tool Does
Clideo is an online video editor that runs entirely in your browser, with no installation required. Its Add Audio to Video tool lets you attach a music track, voiceover, or sound effect to any video file, control the volume of both the added audio and the original sound, and export a finished clip ready to share. It is best suited for creators who need a fast, straightforward solution without committing to a full desktop editing application.

How to Add Audio to a Video in Clideo: Step by Step
Step 1: Open the Clideo Add Audio to Video Tool
Go directly to clideo.com/add-audio-to-video to reach the right feature immediately. Landing on the homepage and searching through menus wastes time, so bookmarking the direct link is worth doing.
Step 2: Upload Your Video File
Click Choose File to open your local file browser, or use the dropdown arrow on the upload button to pull a file from Google Drive, Dropbox, or a public URL.
Clideo accepts the most common video formats, including MP4, MOV, AVI, MKV, and FLV. On the free plan, file size is capped at around 500 MB, so if your video is larger, compress it beforehand or upgrade to a paid plan. Upload time depends on your internet connection and file size.
Step 3: Upload or Select Your Audio Track
Once your video finishes uploading, the “+ Add audio” option will appear on the right side of the editor.
Select the audio file and wait for Clideo to upload it. Once done, the audio clip will appear on the timeline on a new track, below the video clip.
You can upload a file from your device (MP3 and WAV are the most reliable choices) or pull one from Google Drive or Dropbox.
If you want to replace all existing sound in the video rather than layer a new track on top, look for the Mute button (speaker icon below the preview window), which silences everything recorded in the original clip. If you keep it disabled, the new audio and the original video sound play simultaneously, which is useful for adding background music while keeping spoken dialogue intact.
Step 4: Adjust Audio Settings
After uploading, Clideo provides several controls to fine-tune the result:
-
Volume slider for audio and video: Raise or lower the volume of the added audio and video tracks independently.
-
Trim controls via the Trim Audio tool: Shorten the audio file to match the length of your video, or set a specific start point within the audio. Click the Trim button to begin the process.
Take a moment to review these settings before moving forward. Small adjustments here prevent the most common problems that appear after export.
Step 5: Preview and Export
Before downloading, use the Play button to preview the combined result inside the browser. Watch for obvious sync issues between the audio and the on-screen action.
At the bottom-right of the interface, set your desired audio format you want.
When you are satisfied, click Export.
On the free plan, the exported video includes a Clideo watermark in the corner. Upgrading to a paid subscription removes the watermark and unlocks faster processing and higher file size limits. But if you are fine with the watermark, click on the Download button or the arrow button to save the file on your computer, Google Drive, or Dropbox.

Tips for Adding Audio to Video in Clideo Successfully
Follow these practices to get a cleaner result on the first attempt:
-
Trim your audio before uploading. Cutting a clip to roughly match your video length in any basic audio app saves you from fighting Clideo’s in-tool trim controls, which are functional but minimal.
-
Match durations when possible. If your audio and video are very different lengths, pre-edit the audio externally to avoid awkward silence or abrupt cutoffs.
-
Choose WAV over MP3 for voiceovers. WAV is an uncompressed format that preserves the full quality of spoken audio. MP3 works fine for background music, but a voiceover sourced from a WAV file will sound noticeably crisper after export.
-
Start with clean source audio. If you are recording a voiceover or narration to add to your video, the recording quality matters before the file ever reaches Clideo. A plug-and-play wireless mic like the Hollyland LARK A1, which connects directly to a smartphone via USB-C or Lightning and includes 3-Level Intelligent Noise Cancellation, helps eliminate background hiss and room noise from the upload.
-
Export at the highest quality setting available. If the video is destined for online publishing, choosing the best export option Clideo offers preserves both visual and audio fidelity through the final compression.
Limitations of Clideo to Be Aware Of
Clideo handles simple audio-to-video merges well, but know its boundaries before you start:
-
No multi-track audio layering: Only one audio track per project is supported. To combine music with a separate voiceover, pre-mix those audio files elsewhere before uploading.
-
Limited sync precision: There are no frame-level alignment tools. For voiceovers that need to hit specific visual moments exactly, a desktop editor gives more control.
-
Free plan file size cap: Videos larger than approximately 500 MB are blocked on the free tier without compression or an upgrade.
-
Watermark on free exports: Every video exported under the free plan carries a visible Clideo logo, which is not suitable for professional or public-facing content without upgrading.
Frequently Asked Questions
Can I add audio to a video in Clideo for free?
Yes. Clideo’s free plan lets you upload a video, attach an audio track, adjust volume and trim settings, and export a finished file at no cost. The free version adds a Clideo watermark to every exported video. If that is acceptable for your use case, the free tier covers the complete workflow.
How do I replace the original audio in a video on Clideo?
After uploading your video and selecting your new audio file, toggle on the Mute option in the audio settings panel. This silences all audio baked into the original video and plays only your uploaded track. If you leave the option disabled, both the original audio and the new track play simultaneously.
Why is my audio out of sync after exporting from Clideo?
The most common cause is an audio file that is longer or shorter than the video, which causes drift during playback. Check that your audio duration matches the video closely before exporting. Browser performance can also be a factor; closing unnecessary tabs, refreshing the page, and re-exporting often resolve the issue. Re-trimming the audio inside Clideo can fix minor offset problems.
What audio formats does Clideo support?
Clideo accepts MP3, WAV, OGG, and M4A audio files. MP3 is the safest choice for background music due to universal compatibility. If your file is in a format not on this list, such as FLAC or AAC, convert it to MP3 or WAV using a free online converter before uploading to avoid an error.
Does Clideo add a watermark to the exported video?
Yes, on the free plan. The watermark appears as a small Clideo logo on the exported video. Upgrading to a paid subscription removes it entirely and also increases file size limits and processing speed. If you only use the tool occasionally and your video is for personal use, the free plan may still meet your needs.
Conclusion
You only need to follow five simple steps to finish the job. Upload your video, add the audio, adjust the settings, then preview everything. Export the finished video after checking that everything sounds correct. If you often add voice recordings, start with clear, high-quality audio. Good source audio makes a noticeable difference in the final video.
