TEMPORARY MEDIA WORKSPACE / VIDEO COMPRESSOR

Video Compressor

Reduce a video for easier sharing with a controlled H.264 MP4 profile, an optional maximum resolution, and measured output details.

Request-scoped temporary processingAdd one supported file up to 50 MB. Long or unusually large-frame media may be rejected before processing.No account required
Local API readinessMedia service ready

The processor required by this tool is available, and this worker can accept a temporary job.

One bounded job runs per API worker by default.

01
Temporary server workspace

The selected bytes are sent only to the Nirmion media API for this request. Processing uses a private temporary workspace rather than permanent catalogue storage.

02
Request-scoped cleanup

Server-side source and result files are removed when the response stream closes. Re-downloads use the result Blob retained only in this browser tab.

03
Original stays unchanged

Nirmion writes a separately named result containing nirmion_tools and never overwrites the selected source file.

Know the product contract

What goes in, what changes, what comes back

Every media page documents the accepted source, the selected FFmpeg transformation, the output container, and the limits that can affect the job.

IN

Prepare the source

Use a readable video up to 30 minutes and 50 MB. A source already compressed aggressively may have little safe size reduction left.

FX

Apply one operation

FFmpeg decodes the source, scales it only when requested, encodes H.264 video with a bounded quality profile, and encodes available audio as AAC.

OUT

Receive a separate file

The result is a broadly playable MP4. Compare visual detail and audio sync before deleting or archiving the source.

Plain-language method

How video compression changes the file

Compression is lossy. Stronger compression and lower resolution can reduce file size, but cannot restore detail later.

  1. 01
    Choose valid source media

    Use a readable video up to 30 minutes and 50 MB. A source already compressed aggressively may have little safe size reduction left.

  2. 02
    Review the operation settings

    Start with Balanced and 720p for everyday sharing. Use Gentle or the original resolution when fine text and faces matter.

  3. 03
    Inspect and download the result

    The result is a broadly playable MP4. Compare visual detail and audio sync before deleting or archiving the source.

Useful when

Practical jobs this tool handles

  • Prepare a phone video for email or a support ticket.
  • Create a lighter review copy for a team conversation.
  • Reduce dimensions before publishing a simple web clip.

Before processing

Check the source and output choices first

  • Preview the source for corruption and audio sync.
  • Choose a resolution appropriate for the smallest important text.
  • Keep the source until the compressed result is reviewed.
  • Expect complex motion and grain to need more data than static scenes.

Container and codec

Understand the output format

The output is MP4 with H.264 video and AAC audio when audio exists. Source metadata and alternate tracks are not preserved as an archive copy.

Know the boundary

Compression cannot guarantee a target size

The final size depends on duration, motion, noise, source codec, and audio. A very short or already efficient source can occasionally become similar in size or larger.

Quick answers

Questions before you process media

These answers describe the actual upload, FFmpeg processing, download, and temporary-retention contract.

Will this remove the audio?

No. If the source has audio, it is encoded as AAC and kept in the MP4.

Can I choose an exact output size?

No. The profiles control quality and dimensions, not an exact byte target.

Does it overwrite my video?

No. The download has a separate nirmion_tools filename.
