Audio And Video Tools
Convert, trim, extract and compress media using the browser native audio and video stack. These audio and video tools avoid the upload step entirely, which is what makes working with large media files practical online.
Why use browser based audio and video tools
Media files are big. A five minute video can easily exceed a gigabyte, and uploading that to a conversion service, waiting in a processing queue and downloading the result can take longer than the video runs. These audio and video tools sidestep the round trip by using the Web Audio API, the MediaRecorder interface and canvas frame capture to do the work where the file already is.
That does mean the browser sets the boundaries of what is possible, so each tool documents which codecs and containers it supports on the page itself rather than failing halfway through. Where a browser cannot decode a format natively the tool says so up front and points you to the right alternative.
Frequently asked questions
Yes. Every tool in this category is free with no account, no trial and no daily limit. The tools run as JavaScript inside your own browser, so there is no server cost to pass on and no reason to meter usage.
No. Files are read directly from your device into browser memory, processed locally and written back out as a download. Nothing is transmitted, nothing is logged and nothing is stored after you close the tab.
There is no limit imposed by us. The practical ceiling is your own device memory, because the file has to fit in the browser tab while it is being processed. Most machines handle files of several hundred megabytes without trouble.
Current versions of Chrome, Edge, Firefox and Safari on desktop and mobile are all supported. Where a specific tool depends on a capability that a browser has not shipped yet, that tool says so on its own page before you select a file.
