Seamless Extensions Every Time
Our AI keeps the original mix quality, instrument balance, and groove while adding new phrases. Perfect for making extended mixes, DJ intros, or smoother endings.
Style-Matched Generation
AI automatically detects your song's genre, mood, tempo, and key, then generates extensions that perfectly match these characteristics. Works with any music style from classical to electronic.
Flexible Extension Options
Choose from natural continuation for more song content, or outro extension for smooth endings. Extend by 30 seconds to 3 minutes, perfect for making radio edits, extended mixes, or longer versions.
Creator-first extension flow
We hide the plumbing so you can focus on ideas: upload a motif, pick the vibe, and receive a polished long-form cut. Perfect for artists, DJs, editors, and A&R teams who need fast iterations.
1. Upload a highlight
Drop in up to 50 MB of MP3/WAV. Choose the hook or verse that best represents the track.
2. Set the mood
Stay with presets or describe your own prompt, style, and hand-off point—we tune the engine for you.
3. Receive new sections
Within minutes you’ll see fresh versions in history, ready to audition, download, and share.
Campaign-ready edits
Match different runtimes and energy levels for social ads or influencer drops.
Live medleys
Build seamless bridges into DJ drops or long outros for stage moments.
Creative brainstorming
Stretch a short demo into a full structure so the team can iterate faster.
How the AI song extender works
Upload the track you want longer
Drop in an MP3 or WAV. A short loop, an unfinished demo, a 30-second sketch — anything with a clear key and tempo works.
Pick where the extension starts
Choose the point to continue from. The model reads the tempo, key and instrumentation around that point so the new section belongs to the same song.
Preview and download
Listen to the extended version before you keep it. Regenerate with a different continuation point or mood if the first pass is not right.
Make a song longer for TikTok, Reels or an Instagram Story
Short-form video has fixed slots — 15, 30, 60 or 90 seconds — and a loop that ends four seconds early is obvious to anyone watching. Extending the track instead of looping it means the arrangement keeps moving: the drums do not reset, the pad does not jump, and the cut lands where you want it. Upload the clip, extend past the length you need, then trim to the exact frame in your editor.
Extend a Suno track without losing the original feel
Generated songs often stop before the idea finishes — a strong verse and chorus, then nothing. You can upload that track here and continue it rather than regenerating from scratch and losing the take you liked. The continuation follows the key, tempo and instrumentation already in the file, so the second half sounds like the same song rather than a different one bolted on.
For video editors: fill the gap without an audible loop
If you are cutting in Premiere Pro, DaVinci Resolve or Final Cut, the usual fix for a track that is too short is a crossfade loop — and a crossfade loop is audible on any sustained instrument. Extending the source gives you a longer file with real musical movement, so you can lay it under the timeline and cut it where the edit needs to breathe, not where the loop point forces you to.
Part of Pro — about 100 extensions a month
Extending songs is included in Pro ($9.99 a month): 500 credits a month, and each extension costs 5, so about 100 tries. That matters because whether an extension works is not something you can judge from a description — you have to hear whether the transition is seamless on your specific track, and a few tries is enough to find out.
MP3 and WAV in, MP3 and WAV out
Upload MP3 or WAV and download the extended track in the same common formats, so the file drops straight into your editor, your DAW or your phone without a conversion step in between.
Frequently asked questions
How do I make a song longer with AI?
Upload the track, choose the point you want it to continue from, and the model generates a new section that matches the original tempo, key and instrumentation. You preview it before downloading.
Is the AI song extender free?
No — extending songs is part of the Pro plan ($9.99 a month, about 100 extensions). On the free plan you can still make new songs from scratch and listen to everything you make.
Can I extend a song made with Suno or another AI tool?
Yes. Upload the generated track as an MP3 or WAV and continue it from any point, rather than regenerating the whole song and losing the version you liked.
Will the extension sound like a loop?
No — it writes new material rather than repeating the existing bars. The new section follows the same key, tempo and instrumentation, so it reads as a continuation instead of a repeat.
What file formats can I upload?
MP3 and WAV are supported for both upload and download, which covers most exports from phones, DAWs and video editors.
How much longer can the track get?
You can extend in passes and run the result through again to keep going. Longer extensions are the point at which most people move to a paid plan.
Can I use the extended track in a video?
Check the pricing page for the licensing that applies to your plan before publishing or monetising anything you generate.
Why does my extension sound off-key?
Usually because the chosen continuation point sits mid-phrase or mid-chord change. Move the start of the extension to a bar line or the end of a phrase and regenerate.
Start from a song instead
If you do not have a track to extend yet, generate one first and come back — or make a personalized song for someone from your own story.
