Edit audio online: trim, clean up and split tracks
Most audio jobs are small. Cut the dead air from a voice memo, turn an OGG file into an MP3, pull a sentence out of an interview, or get a backing track to sing over. None of that needs a desktop audio workstation, and browser tools now cover each of these jobs. This guide is for people who want to finish one of them today without installing software. The four tools here differ in three ways that matter before you pick. First, where your audio goes. Two of them process the file on your own device, and two upload it to a server. Second, what kind of editing they do, since trimming a waveform, editing speech by its transcript and separating instruments are different tasks. Third, what's free and where the paid line sits.

Check where the file goes first
A browser tool can work in two ways. Some decode and process the audio inside the tab, so the file stays on your computer and closing the tab clears it. AudioDing and AudioEditDesk both say they work this way. That suits recordings you'd rather not hand to anyone, such as a client call or an unreleased song. The cost is that your own device does the work, so large files need memory and heavy jobs take time.
Others upload the file and process it on their servers. Hilite and Extract Stems work this way. Read the retention terms whenever a tool uploads. Extract Stems, for example, says results expire 7 days after completion and that its separation is processed by Replicate.
Match the tool to the kind of edit
For music or sound files, the usual jobs are trimming, joining, converting formats and fixing levels. A waveform editor is the right shape for that, and the two local tools here both do it.
Spoken audio is different. In an interview or a solo episode, most of the editing is deciding which sentences stay. Editing through a transcript lets you find the words and cut them, which is the approach Hilite describes.
Separating vocals from instruments is a third job. It gives you a karaoke track, an a cappella or a practice backing. A dedicated stem splitter offers more parts and output formats, while AudioEditDesk includes a simpler vocals and backing split that runs on your device with a 10-minute limit.
Limits you will run into
Free browser tools cap file size or length. Here the caps run from 50 MB per file to 500 MB on desktop, and stem separation is limited to 10 minutes of audio per file in both tools that offer it. The local tools work in the open tab and don't keep projects, so download your result before closing it.
Rights are your responsibility. These tools will process whatever you give them. AudioEditDesk's terms, for instance, ask you to use audio you own or have permission to edit. That matters most when you split a commercial song.
A quick way to choose
If the file is private, or you only need a trim or a format change, start with one of the two local tools. AudioEditDesk is the simpler screen for a single file, and AudioDing has more tools if you also need tags, tempo or noise removal.
If the audio is speech and the edit is about which sentences stay, use a transcript editor such as Hilite and accept that the recording is uploaded. If you need separate instrument parts in a lossless format, a stem splitter such as Extract Stems is built for that, and $2.99 covers 15 minutes of audio.
The projects
AudioDing
Good for: A wide set of free audio tools with nothing uploaded
AudioDing is free with no account. Its menu covers trimming, splitting, combining and reversing audio, a normaliser, an MP3 tag editor, format conversion including pulling audio out of video files, and analysis tools such as a BPM and key finder and instrument tuners. Noise removal, speech to text and text to speech run on your device. The site says audio is never uploaded and that audio content and filenames are kept out of analytics. The trim tool lists a 50 MB file limit, and the interface comes in 11 languages.
AudioEditDesk
Good for: Trimming or converting one file quickly
AudioEditDesk opens MP3, WAV, M4A and OGG files and exports MP3 or 16-bit WAV. Tools include a cutter, converter, loudness normaliser, volume, fades, reverb and filters, plus a vocals and backing split limited to 10 minutes and 100 MB. Everything is free with no account, and the privacy page says audio is processed in your browser and not uploaded. Desktop files can be up to 500 MB and mobile files up to 100 MB. It handles one file at a time, and refreshing or closing the tab clears the project.
Hilite
Good for: Editing a podcast episode by its transcript
Hilite is a podcast tool for recording, editing, enhancing and publishing in one place. You edit by working through the transcript, then listen before exporting. Your recordings, transcripts and edits are stored with your account, and the privacy policy, last updated July 29, 2026, names the operator as Shanda Technologies Inc. On October 9, 2026 its pricing page listed a free plan with one episode a month of up to 30 minutes and a Pro plan at $19 a month. Confirm the current episode allowance on the pricing page before planning a release schedule around it.
Extract Stems
Good for: Splitting a song into vocals, drums and other stems
Extract Stems separates a file into 2, 4 or 6 stems and exports MP3, WAV or FLAC. Uploads can be up to 100 MB and 10 minutes. A verified account gets 5 free minutes with no card. After that you buy minutes once, with no monthly plan. Packs run from $2.99 for 15 minutes to $29.99 for 300, and purchased credits don't expire. Audio is uploaded, and the privacy page says separation is processed by Replicate, uploads aren't used to train AI models and results expire 7 days after completion.
How these projects were chosen
Every pick has a published Project Note on this site. Projects were matched to this task from their own public pages, which were read on November 11, 2026, apart from one dated price noted in its entry. Prices and limits can change, so confirm them on each site before paying. Nobody can pay for a spot in this guide.
Placement on Project Radar is never paid for, and none of the projects in this guide is sponsored.
