Which file formats can I clean?

Audio: MP3, WAV, M4A, AAC, FLAC, OGG and OPUS. Video: MP4, MOV, MKV, WebM and AVI. The free tier accepts files up to 500 MB.

Do you upload or store my files?

Your media is uploaded to secure object storage (Cloudflare R2), processed by our cloud worker (Modal), used only to produce your cleaned output, and deleted by retention cleanup — normally within 7 days. Read the Privacy Policy for details.

What does the free Starter plan include?

Every account gets a one-time lifetime grant of 30 free minutes that never resets. Upload files and preview the full original vs. cleaned result online at no cost. Unlocking the full output first uses those 30 minutes and any other paid balance; only when your balance runs out does the one-time $2.49 purchase appear.

How is Pay As You Go different from Subscription?

Subscription plans give you 10, 30 or 100 hours of cleaning per month. Pay As You Go sells prepaid cleanup credits that never expire — ideal when you clean in bursts.

Can I preview before downloading?

Yes. The before/after comparisons on this page run entirely in your browser, and completed cleanups offer an instant A/B preview before you download the result.

Will cleaning change the quality of my audio?

Noise reduction can change speech or music when noise overlaps the signal. Compare Original and Cleaned playback, listen for metallic or thin speech, and keep the original. SimpleClean returns MP3 for audio and MP4 for video.

Noise types that fit
