Convert Video and Audio Files with Media Converter

What Media Converter does

Media Converter converts supported local video and audio files into other common formats using Kivrum's dedicated FFmpeg service. It accepts a range of input formats—MP4, MOV, AVI, MKV, WebM for video and MP3, WAV, FLAC, M4A, OGG for audio—lets you choose a supported output format, processes the file, and provides a download of the converted result. Uploaded files are processed and automatically deleted, and conversion happens on Kivrum's processing service.

Before you convert: prepare your file

Work locally with a copy of any file you plan to convert. Media Converter requires uploading a local file; prepare the file on the device you will use and confirm the file type is one of the supported inputs. If you plan to extract audio from a video, decide on the audio format you need (for example MP3 or WAV). If you need a specific playback container or codec later, identify the desired output format ahead of time.

Check that your network connection can comfortably upload and download the file you intend to use. Because Media Converter processes files on Kivrum’s FFmpeg service, conversion speed depends on the file and the processing environment; allow sufficient time for the service to complete the job. For important files, keep a local backup before uploading.

How to convert a file with Media Converter

The following steps walk through a typical conversion using the Media Converter route. They use only the tool’s documented behavior: upload, choose output, process by Kivrum's FFmpeg service, and download. Keep a local backup until the download completes successfully.

1. 1

   Open Media Converter

   Visit the Media Converter tool at /tools/media-converter. The tool interface guides file upload and conversion options.

2. 2

   Upload your local file

   Select the file you prepared on your device. Media Converter accepts the documented formats: MP4, MOV, AVI, MKV, WebM for video and MP3, WAV, FLAC, M4A, OGG for audio. Use a copy rather than the only original if you want to keep an untouched master.

3. 3

   Choose an output format

   From the available output options, pick the format you need. Select an audio output if you’re extracting sound, or a video output if you want a different container or format. The interface presents only supported choices for conversion.

4. 4

   Start the conversion

   Submit the job. The file is sent to Kivrum’s dedicated FFmpeg processing service. Wait for the service to complete the conversion; progress or completion indicators are shown in the tool interface when available.

5. 5

   Download the converted file

   When processing finishes, download the converted result to your device. Verify playback in an appropriate media player to confirm the conversion produced the expected format and quality.

6. 6

   Keep your files and clean up

   After you’ve verified the downloaded file, delete any temporary copies you created locally. Uploaded files are processed and automatically deleted by Kivrum’s service; keep local backups only as needed.

What to expect after conversion

After a successful run you receive a converted file in the chosen format that you can download immediately. Because Media Converter uses FFmpeg on Kivrum’s processing service, conversions typically preserve the media content while changing the container or encoding to the selected output format. Always test the downloaded file in the application or device where you will use it, since playback behavior can vary across players and codecs.

If the output doesn’t behave as expected—missing audio, incompatible container, or playback issues—revisit the output format choice and try an alternative supported format. For audio extraction from video, selecting MP3 or WAV commonly produces a file usable in most audio players and editors.

Privacy and temporary-file deletion

Media Converter processes files on Kivrum’s dedicated FFmpeg service. The tool description specifies that files are processed and automatically deleted. Use this feature to minimize persistent exposure of uploaded files. For sensitive media, keep local backups and remove any unnecessary copies after you verify the converted download.

Responsible-use guidance: do not upload media you are not authorized to share or convert. Respect copyright, personal privacy, and any legal restrictions that apply to the media you handle. If a file contains personally identifiable information or sensitive content, consider performing conversions on local, offline tools instead of uploading to a processing service.

Common problems and how to fix them

Unsupported format error: If the tool rejects your file, confirm the file’s format matches one of the supported inputs—MP4, MOV, AVI, MKV, WebM for video or MP3, WAV, FLAC, M4A, OGG for audio. Some files may use uncommon codecs inside a supported container; in that case, re-encoding locally or using a different input may help.

Interrupted upload or slow processing: If your network connection is unstable, the upload or download may fail. Retry the conversion when you have a stable connection. Keep a local copy of the original file so you can re-upload without losing content.

Unexpected playback issues: If the converted file doesn't play as expected, try a different output format or open the file in a versatile media player that supports many codecs. If problems persist, re-run the conversion selecting an alternate format that better matches your target device or application.
