Where can I master a song online for free and download it?

Selekt provides free browser mastering and 16/24-bit WAV downloads without an account or upload. BandLab also offers unlimited WAV and MP3 downloads using its free presets. Songmastr includes seven free masters per week.

Is LANDR mastering free?

The preview is free; keeping the finished master requires a purchase or qualifying subscription. Its checked FAQ quotes $10 for a one-time single-track master. Review the included file formats at checkout.

Is BandLab mastering really free?

Yes: its current help page documents four free presets and unlimited WAV/MP3 downloads. Membership adds presets and further controls. Cloud processing means the recording is uploaded.

Can I master without uploading my song?

Yes. Selekt processes the audio in your browser, and local Matchering processes on your own computer. Cloud mastering services require an upload even when their controls appear in a browser.

Is free mastering as good as a mastering engineer?

This guide did not conduct a listening test that could establish that. Automatic tools can be useful for previews and straightforward releases, but an engineer can make context-dependent decisions, spot mix problems and discuss the result with you. Compare at matched loudness before deciding.

1Selekt Audio

Our number-one pick for a free private browser master: no account, no audio upload and a finished 16/24-bit WAV you can keep. Eight styles, destination targets, tonal shaping, compression, loudness adjustment and peak limiting sit in one workflow, with original/mastered listening and before/after measurements. You can prepare an unreleased mix, compare it and keep the result without a subscription or pay-to-download gate.

What free mastering includes

Run, compare and download for $0: no account, no audio upload and no added watermark. The mastering work runs on your device.
Eight styles: General / Streaming · Hip-hop / Trap · Pop · EDM / Electronic · Acoustic / Singer-songwriter · Classical / Archival · Rock / Band · Lo-fi / Chill. The engine applies style-based tonal shaping, gentle compression, loudness adjustment and peak limiting.
Choose a destination: Match style · Release · Social streaming · Apple Music · Loud / club. Match style remains the default; other choices select a loudness target rather than changing the underlying performance.
Listen before keeping it: switch between original and mastered audio, inspect before/after loudness and peak information, and choose 16- or 24-bit WAV export. The 16-bit export applies dither.
Continue only if useful: optional next steps can send the finished audio into other Selekt tools. Those tools show their own terms; they are not a fee for mastering. Browser/device limits and source quality still affect what a master can achieve.

What to watch for: This is browser DSP, not a measured claim to beat every cloud engine or a human engineer on a critical release.

Best for: A free private browser master. Price: $0, including WAV download.

2BandLab Mastering

BandLab deserves its free recommendation. Its current help page documents unlimited WAV and MP3 downloads, while Membership adds further presets and controls.

What to watch for: Audio is uploaded. Additional presets, intensity and EQ have tier-dependent membership gates.

Best for: Generous free cloud mastering. Price: $0 for free presets and downloads.

3Songmastr

Uses Matchering and a reference song to match broad sonic characteristics. The free allowance may be enough for occasional work; its paid packs are separate.

What to watch for: Reference choice matters. Matching an unsuitable reference can push the song in an unsuitable direction.

Best for: Occasional reference matching. Price: $0 for 7 masters/week; extras from $4.

Source: www.songmastr.com (1) · www.songmastr.com (2)

4Matchering

Run the reference-based engine on your computer rather than paying a hosted service. Its code and installation instructions are public.

What to watch for: You install and operate it and supply a suitable reference. It is not an instant hosted browser service.

Best for: Technical users wanting local reference matching. Price: $0 open source; your computing cost.

5AI Mastering / Bakuage

The maker lists target loudness, mastering-level controls and analysis on its $0 unlimited-mastering offer.

What to watch for: Account/upload workflow differs from local browser processing. This guide did not test every export combination.

Best for: Free cloud loudness and mastering controls. Price: $0/month Free.

6LANDR

Its current FAQ quotes $10 for one master and documents album matching, references and level-matched previews. These workflows can justify paying beyond a quick free pass.

What to watch for: A free preview is not a free finished-file download. Subscription output formats vary by tier.

Best for: Album/reference mastering and paid release workflows. Price: $10 one-time single-track master.

Source: www.landr.com

7Waves Online Mastering

The checked single-credit offer is $3.99, with a five-credit pack at $17.45. Compare the actual pack total rather than assuming a per-track headline buys only one file.

What to watch for: The preview does not provide the complete master. Offers and pack pricing can change.

Best for: A paid one-off export. Price: $3.99 / one credit in checked offer.

8eMastered

The official site offers a free starting preview; its billing help distinguishes monthly and annual commitments. A paid dollar quote was not readable during this check.

What to watch for: Yearly billed monthly is still an annual commitment. Check the checkout total and download entitlement.

Best for: A paid subscription workflow. Price: Paid subscription; USD quote not verified.

What does “free mastering” actually mean?

Free with download means you can keep a finished audio file without paying. A free preview lets you hear a result but requires a purchase to export the complete master. Paid-only tools have no finished free route at all. Do not count a 30-second preview as a free mastered song.

Local open-source software has no hosted per-track fee, but it takes your computer’s resources and your setup time. A subscription price shown per month can also be an annual commitment; compare the total checkout amount.

Which LANDR alternative fits what you want to change?

For price: start with Selekt or BandLab and download a real finished file before paying elsewhere. BandLab’s free tier is genuinely generous; there is no need to call it preview-only to make a comparison.

For privacy: Selekt runs in the browser without uploading the recording; Matchering can run on your own computer. For control: a local reference workflow lets technical users operate the engine, while a DAW or mastering engineer offers deeper manual decisions. LANDR’s album/reference workflow and release services may be more valuable if that is the job you need.

How should I compare a master to my original?

Use similar listening volumes. A louder version often sounds better at first simply because it is louder. Listen for squashed drums, distortion, harsh high notes and changes to the vocal balance, then keep the version that serves your song.

Mastering does not reliably remove a wrong note, isolate a singer or repair a badly clipped recording. Fix the underlying mix or restoration problem first where possible. These recommendations compare terms and controls, not a controlled sound-quality test.
