Free online audio and video tools for cutting, converting, compressing and recording, all running inside this browser tab. Trim a long take with the Audio Trimmer, pull the sound out of a clip with the Video to Audio Extractor, or shrink a file with the Video Compressor. Nothing is uploaded.
Most visits start with a cut or a convert. The Video Trimmer takes a long recording down to the part you want, the Audio Format Converter changes a file into the format something else will accept, and the Audio Normalizer levels out a set of interviews recorded at different volumes. The Silence Trimmer takes dead air off the front of a take, and the Screen Recorder captures what is on your screen without anything to download first.
Subtitle work is where small mistakes show. The Subtitle Time Shifter moves a whole track back half a second when the dialogue lands late, the SRT to VTT Converter swaps between the two formats players expect, and the LRC Lyrics Timing Tool lines lyrics up line by line. Big video is the other thing to plan for: there is no maximum file size beyond what your device can hold in memory, so very large clips lean on your own machine.
Nothing here talks to a server. Your file is read by the page, processed by your own computer, and written back out as a download, so there is no upload progress bar, no queue, no daily limit of five files, and no account to create before you can export. That matters most for the personal stuff: a take from the Voice Recorder with Trim, a shot from the Webcam Photo Booth, or an interview you were trusted with stay on your own phone or computer.
Yes. Every tool on this page is free to use with no account, no email address, no trial period and no watermark on anything you export. There is no paid tier, so there is nothing gated behind an upgrade prompt. Because the processing happens on your own device rather than on rented servers, there is no per-file cost to recover, which is why there are no daily limits or file size caps either.
It depends entirely on whether the tool uploads your file. Most online converters and trimmers send your media to their servers, where it sits on third-party infrastructure until their retention policy deletes it. These tools never upload anything. The page loads once, then reads your file locally through the browser and does the work with your own processor. You can confirm this by opening your browser's network tab, or by disconnecting from the internet after the page loads and using a tool anyway.
They handle whatever your browser can decode, which in practice covers MP3, WAV, M4A, AAC, OGG and FLAC for audio, and MP4, WebM, MOV and MKV for video, plus SRT, VTT and LRC for subtitle and lyric files. There is no imposed size limit. The practical ceiling is your device's available memory, so a multi-gigabyte screen recording works on a desktop but may struggle on an older phone. Large video files also process faster on a machine with more CPU cores.
