Pick a target container (or MP3 for audio only), then press Convert.
Converting…
This page re-packs or re-encodes a video so it matches the container another app, phone, or website expects. A phone export in MOV, a browser recording in WEBM, or an older AVI clip can all need a different wrapper before they upload or open cleanly. Sound Booster’s Video Converter is built for those everyday swaps — not for multi-track film finishing.
You drop a file, choose MP4, WEBM, MOV, MKV, or AVI, convert in the browser, and download the result. When you only need the soundtrack, MP3 export pulls audio out of the clip. The flow is meant to stay on your device, so routine files do not have to be sent to a remote server just to change format.
Browser support still decides what can be decoded. Short and mid-length clips work best; very long 4K sources may need more memory than a typical laptop tab can give.
Encoding is designed to run inside your browser session. That keeps simple format changes closer to your machine instead of depending on an upload queue on someone else’s server. You stay on the page until progress finishes, then download the result or save it to Your Library.
Switch among MP4, WEBM, MOV, MKV, and AVI when a platform demands a specific container. Need only the sound? Export MP3 from the same file without jumping to a separate audio site. One workspace covers everyday container swaps and soundtrack extraction.
Save a converted clip into Your Library and reuse it later on Volume Booster or other tools on Sound Booster — one place for files you already processed. No extra account is required to keep a short list of recent exports on this device.
Open the page, convert, and download. There is no mandatory sign-up wall and no watermark stamped onto the file by this tool. That makes it practical for one-off jobs: a phone clip for a form, a screen recording for a teammate, or a quick remux before editing.
Keep this tab active until the progress bar finishes. Closing the page mid-encode cancels the job.
Drop a video on the panel, pick one from disk, or load an item from Your Library. Wait until the file name and length appear in the card.
Select MP4, WEBM, MOV, MKV, AVI, or MP3 for audio-only. Matching the source extension is removed from the list so you always pick a real change.
Start conversion, then download the output or store it in Your Library. Prefer MP4 if another format fails on your browser.
MP4 is the default for phones and social uploads. WEBM suits many browser-first workflows. MOV is common from Apple cameras and some editors. MKV and AVI cover broader desktop playback. MP3 strips the picture and keeps the soundtrack. What you can open as input still depends on codecs built into your browser.
No. Conversion is designed to run locally in the browser. Your file is not uploaded to Sound Booster servers for this step.
Re-encoding can change bitrate and codecs compared with the original. The tool aims for a practical balance for web and device playback. For archival masters, keep a copy of the source file.
Yes. You can convert without creating an account on this page. Browser and device limits still apply for very large files.
No desktop installer is required for the core flow. Some formats use an in-browser encoder that may download once on first use, then run locally.
You can target MP4, WEBM, MOV, and MKV. Input support depends on your browser — MP4 and WEBM are the most widely accepted starting points.
Some codecs are missing in certain browsers, and heavy files can run out of memory. Try Chrome or Edge, a shorter clip, or MP4 output first. Keep the tab in the foreground until encoding completes.
