You can add audio to Instagram posts in three ways: use Instagram's built-in music library, upload audio you own, or add sound during the editing process before you post
Instagram lets you attach sound to a photo or video post through its music sticker, the Reels feature, or by uploading your own audio file. The method depends on what kind of audio you want to use and whether you're posting a still image or video. Built-in music from Instagram's library is the simplest route and works on both photos and videos. If you want to use your own recording — a voiceover, podcast clip, or original song — you'll need to either add it before posting or use the Reels editor, which gives you more control over timing and volume.
Key Takeaways
- Instagram's music sticker works on photos and videos and connects to a licensed library of millions of songs, but you cannot upload your own audio through the sticker alone.
- Reels let you add your own audio files or record sound directly in the app, and you can trim, adjust volume, and sync audio to video before posting.
- If you want to add audio to a photo post, the music sticker is your only option — regular photo posts do not support custom audio uploads.
- Audio you upload must be in a format Instagram accepts, typically MP3 or AAC, and cannot be longer than the video or Reel duration.
Adding music from Instagram's library to a photo or video
The music sticker is the fastest way to add sound to any post. Open the post editor, take or select your photo or video, tap the sticker icon (it looks like a square smiley face), and choose "Music." Search for a song by title, artist, or mood. Instagram will show you a preview of how the audio sounds and let you choose which part of the song plays — you can trim it to 15 seconds or less for most posts.
Once you select the song and the section you want, tap "Done" and the audio attaches to your post. The music sticker shows on your post so followers know what song is playing. This method works for both photos and video posts, and the audio will play when someone views your post in their feed. Keep in mind that Instagram's music library is licensed, so the songs you add are the same ones available to all users — you're not uploading anything yourself.
Uploading your own audio using Reels
If you want to use audio you recorded or own — a voiceover, podcast segment, or your own music — Reels is the tool that lets you do it. Open Instagram, tap the "+" icon, select "Reels," and either record video directly in the app or upload a video file you already have. Once your video is in the editor, tap "Audio" at the bottom of the screen.
You'll see three tabs: "Your audio," "Trending," and "For you." Tap "Your audio" to access recordings saved on your phone. If you want to record audio directly in the app instead of uploading a file, tap the microphone icon and record your voiceover or sound while watching your video play. You can record multiple audio tracks and layer them — for example, background music plus a voiceover. Adjust the volume of each track by tapping the volume slider next to it, and trim the audio to match your video length using the timeline at the bottom.
Preparing audio files before you upload
Audio files need to be in a format Instagram accepts. MP3 and AAC are the most reliable formats — if you have audio in another format like WAV or FLAC, convert it using a free tool like Audacity or an online converter before you try to upload it to Instagram. The file size should be under 4 GB, though most audio files are much smaller than that.
Check the length of your audio file and make sure it does not exceed the length of your video. If your video is 30 seconds long, your audio should be 30 seconds or shorter. If your audio is longer, trim it in a basic audio editor or in the Reels editor itself before posting. Test the audio on your phone by playing it back to make sure the volume is clear and the file plays without errors.
Adding audio during video editing before you post
You can also add audio to a video post by editing the video on your phone before you upload it to Instagram. Use a video editor like CapCut, iMovie (on iPhone), or Adobe Premiere Rush to combine your video and audio file, adjust the volume, and sync them together. Once the video and audio are merged into a single file, upload that finished video to Instagram as a regular post or Reel.
This method gives you the most control because you can edit the audio and video together, add effects, and make sure everything is timed correctly before Instagram ever sees the file. The downside is that it takes more steps and requires a separate app. Use this approach if you need precise control over audio timing, volume levels, or if you want to add multiple audio tracks that Instagram's built-in editor does not support.
What happens to audio when you post and share
When you post a photo or video with audio, followers will hear the sound when they watch your post in their feed. If they have their phone on silent, they will not hear it unless they tap the post to unmute it. Audio from Instagram's music library will show the song title and artist on your post, and followers can tap to listen to the full song on Spotify or Apple Music if they want.
If you upload your own audio, Instagram will not display the artist or song information — it will just play the sound. Your audio will not appear in Instagram's music library or be available for other users to add to their posts. If you share your post to other platforms like Facebook or TikTok, the audio may or may not carry over depending on how you share it and whether those platforms recognize the audio format.
Troubleshooting audio that will not upload or play
If your audio file will not upload, check that it is in MP3 or AAC format and that the file size is under 4 GB. If the file is in a different format, convert it first. If the audio uploads but does not play, make sure your phone's volume is turned up and that the audio track is not muted in the editor. Tap the volume icon next to the audio track to unmute it if needed.
If you are using Reels and the audio cuts off before the video ends, the audio file is probably shorter than your video. Either trim the video to match the audio length, or add a second audio track to fill the remaining time. If you recorded audio directly in the Reels editor and it sounds muffled or quiet, re-record it in a quieter space and hold your phone closer to your mouth. Test the audio by playing back the Reel before you post it.
Frequently Asked Questions
Can I add audio to a regular photo post without using Reels?
No. Photo posts only support the music sticker, which pulls from Instagram's licensed library. You cannot upload your own audio to a photo post. If you need to add custom audio, convert your photo into a video (even a still video with no movement) and post it as a Reel instead.
What if the audio file I want to use is longer than my video?
Trim the audio in the Reels editor before you post. Tap the audio track in the timeline and drag the edges to shorten it to match your video length. Alternatively, trim the audio in a separate audio editor on your phone before uploading it to Instagram.
Will my followers hear the audio if their phone is on silent?
No. If a follower's phone is set to silent mode, they will not hear audio from your post unless they tap the unmute icon that appears on the video. This is true for both music from Instagram's library and custom audio you upload.
Can I use copyrighted music if I upload it myself?
Uploading copyrighted music you do not own may result in Instagram muting the audio or removing your post. Use only music you created, music in the public domain, or music you have permission to use. If you are unsure whether a song is copyrighted, use Instagram's music library instead, which handles licensing for you.
Does the audio stay with my post if I share it to Facebook or TikTok?
It depends on how you share it. If you cross-post directly through Instagram's sharing settings, the audio usually carries over. If you read the video and upload it separately to another platform, the audio will stay in the file. However, some platforms may not recognize custom audio formats or may compress the audio quality.
