How to add a voice recording to Canva

Open your design, go to the Uploads tab in the left panel, and click Upload files. Choose your audio file and it appears under the Audio section of that panel.

Click it once and it attaches to the design, appearing as a bar underneath the timeline at the bottom of the editor. Drag its ends to trim, and drag the bar itself to move where it starts.

Canva accepts MP3, M4A, WAV, OGG and a few others, with a file size limit that varies by plan. If an upload fails without explanation, size is the usual cause, and exporting as a 128 kbps MP3 rather than a WAV usually solves it.

Audio uploaded this way works in presentations, videos, and social posts. It is the route that works everywhere.

For presentations, Canva has a built-in recorder. Click Present, then choose Present and record. It gives you a teleprompter view with your slides and records your camera and microphone as you talk through them.

This produces a recorded presentation with a shareable link rather than an audio track sitting on the design. It is the right tool for a talk you want to send someone, and the wrong one if you wanted narration baked into an exported video.

Know which output you need before you start, because moving between the two afterwards means redoing the recording.

In a presentation or video, each page has a duration, and the audio runs underneath all of them. Getting narration to land on the right slide means adjusting page durations to match the voice, not the other way round.

Click the timer icon on a page to set its duration, or drag the page edges in the timeline view. Play from the start after each change, because adjusting one page shifts everything after it.

A practical trick: write the script first, note roughly where each slide should change, and leave a short pause at each transition when you record. Those pauses give you something to aim at, and a slide change on a pause looks deliberate rather than early.

Canva allows more than one audio track, so you can put music under a voiceover. Select each track and use the volume control to set the balance.

Set the music far lower than feels right while you are working. Background music should sit around 15 to 20 per cent of the voice level. It will sound too quiet in the editor with your full attention on it, and correct to a viewer who is listening to the words.

Use Canva's own audio library for music where you can. It is licensed for use in Canva designs, which removes the question of whether you can publish the result.

Canva gives you volume, fade in and fade out, and trimming. There is no noise reduction, no compression and no way to remove a filler word without cutting the audio at that exact point, which usually leaves an audible seam.

So whatever you upload is essentially what gets published. A voiceover with room hum, uneven levels or a lot of ums will stay that way through the design.

The sequence worth following: record the voice, clean and level it elsewhere, export an MP3, then upload the finished file to Canva and build the visuals around it.

Hilite handles that middle step in the browser, including removing filler words and noise. We make it, so weigh that as you like. Audacity does the same thing free with more manual effort.
