Batch convert multiple video and audio files at once - privately in your browser
Add multiple clips and convert them all to a common format in one go. Each file is processed sequentially in your browser with no uploads, so your footage stays private. Ideal for standardising phone recordings, preparing files for an editor, or archiving a batch of clips as MP4.

🔒 Your files never leave your device - 100% private & secure
Drag multiple video or audio files onto the page, or click Select Files to browse. You can add more files at any time with the Add More Files button.
Select a target format - MP4, WebM, MOV, MKV and others for video, or MP3, AAC, WAV, FLAC, OGG for audio. Optionally adjust the resolution and quality level. All files in the batch use the same settings.
Click Convert All. VidShift processes each file sequentially in your browser using WebAssembly - nothing is uploaded to a server. A progress indicator shows the status of each file.
When all conversions are complete, click Download All to save every file at once, or download individual files from the queue.
Batch conversion saves time when you need to standardise a collection of clips - for example, converting phone recordings from different devices into a single format for editing, preparing a folder of videos for upload to a platform that requires a specific format, or archiving old footage into a modern, space-efficient container. Instead of converting files one by one, you can queue them all up and let VidShift handle the rest.
Select or drag multiple video and audio files, choose your output format, resolution and quality, then click Convert All. VidShift processes each file sequentially using WebAssembly and WebCodecs - entirely in your browser. Nothing is uploaded to a server.
There is no hard limit on the number of files. The practical limit depends on your device's available memory. Each file is converted one at a time, so even large batches will complete - they just run sequentially. You can add more files to the queue at any time. To compress files individually with more control, try the video compressor.
Yes. You can mix video and audio files of any supported input format in a single batch. All files will be converted to the same output format you select. Supported inputs include MP4, MOV, MKV, WebM, OGG, MP3, WAV, AAC, FLAC, and MPEG-TS.
No. Just like the single-file converter, the batch converter runs entirely in your browser. Your files never leave your device. There is no server involved - all processing uses your computer's local resources.
No. VidShift never adds watermarks, logos, or overlays to any of your converted files - whether you convert one file or a hundred. Many online batch converters watermark output unless you pay. VidShift is completely free with no watermarks on any file.
Yes. Once all files have been converted, a Download All button appears which downloads every converted file. You can also download individual files as they complete by clicking the download icon next to each file in the queue.
If a file fails, VidShift marks it as failed and moves on to the next file in the queue. The rest of the batch continues processing normally. You can still download the files that converted successfully.
VidShift Batch Converter lets you convert multiple video and audio files at once, entirely in your browser.

Add as many files as you need, pick a format, and convert them all with a single click. Your files never leave your device - making it the most private way to batch convert media files online. No watermarks, no signups, no file limits. Supports MP4, WebM, MKV, MOV, MP3, FLAC, WAV and more.
