MP3 Trimmer review
A focused web tool for quick waveform trimming, looping, previewing, and export.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
MP3 Trimmer is a browser-based audio-cropping workflow from Suno, Inc., designed for beginners, songwriters, producers, and other music creators who need to shorten tracks, remove silence, select sections, or loop clips. It works with MP3 and WAV files and uses a waveform interface for range selection. Users can preview a selected range, crop audio from the beginning, end, or middle, then save the result as a new file without overwriting the original. The tool operates within Suno Studio and is available on the web.
Pricing follows a freemium model. The Free Plan costs $0 per month and includes 50 credits per day, basic editing such as crop and fade, and uploads of up to 8 minutes of audio. The Pro Plan costs $8 per month when billed monthly and provides 2,500 credits per month, 20 song downloads per month, and Standard and Pro features. The Premier Plan costs $24 per month when billed monthly and adds access to Suno Studio, 10,000 credits per month, and advanced editing. For occasional short edits, the Free Plan covers the core workflow; paid tiers are more relevant for higher usage, downloads, or Studio-based editing.
Its main strength is a narrow, understandable editing flow: select a range on the waveform, preview it, and export a new file. Draggable flags support trimming and looping, while Suno Studio extends the workflow to a multitrack timeline. That focus suits users who want quick browser-based edits without a broader production environment. It is less suitable for creators seeking a full audio editor centered on extensive production, sequencing, or complex editing workflows. Choose MP3 Trimmer for straightforward online cuts and loops; choose an alternative when your work requires a wider editing scope.
