Batch video converter for multiple files
Batch convert multiple videos to MP4 or WebM, or extract MP3 and WAV audio in one queue. Every file is processed on this device with no upload or watermark.
Convert multiple videos to MP4, WebM, MP3 or WAV
Choose one output format, add several video or audio files and let MedleyKit process the batch sequentially. Each result is checked before download, while the complete queue and media bytes stay on your device.
Convert multiple videos to MP3 or WAV
Choose MP3 to extract compact audio from every compatible file, or WAV for lossless PCM output. Files without a decodable audio track are reported without stopping the rest of the batch.
Run one dependable local conversion queue
Only one encoder runs at a time for stable browser performance. Each local result is checked for a readable container, duration, codec and expected tracks before download, while failed items keep their own error.
Local processing
Your source video and generated results are processed on this device instead of being uploaded to a remote media-processing server.
Focused tools
Each editing step has its own dedicated page, keeping the controls, choices and interactions simple.
Continuous workflow
Pass a local result directly to another compatible tool and combine multiple editing steps in the same browser on this device.
Batch video conversion questions
Answers about converting multiple files, extracting audio and keeping the complete batch local.
Can I convert multiple videos at once?
Yes. Add several video or audio files, choose one output profile and start the queue. MedleyKit processes files one at a time for stable browser performance, keeps each item's progress visible and continues to the next file if one conversion fails.
How do I batch convert videos to MP4?
Add all compatible source files, choose the MP4 profile, select a quality and maximum resolution, then use Convert all. Each file is encoded as an H.264/AAC MP4 and checked for readable duration, container and expected tracks before download.
Can I batch convert videos to MP3?
Yes. Choose the MP3 output profile to extract the primary decodable audio track from every compatible file in the queue. Video-only files are reported individually, while files with audio continue to compact MP3 results.
Which batch conversion formats are supported?
The converter accepts common video and audio containers including MP4, MOV, M4V, WebM, MKV, MP3, WAV, FLAC, OGG and AAC. It creates MP4, WebM, MP3 or WAV using validated codec and container combinations supported by the browser.
Are my files uploaded during batch conversion?
No. File analysis, encoding, temporary results and validation stay in the browser on this device. You do not need an account, and MedleyKit does not add a watermark to converted video files.
