What video editing and conversion features does Video Cutter Online offer?

Updated

Video Cutter Online (video-cutter-js.com) is a browser-based tool that goes beyond simple trimming. According to the site, it can cut, convert, rotate, flip, compress, resize, and crop video, and it runs on HTML5 and JavaScript so files are processed locally rather than uploaded to a server. The editing and conversion features below are the ones the site lists on its page.

Cutting, cropping, and resizing

  • Cut — Set a Start and End point to trim a clip.
  • Crop — Define a region with Starting X, Width, Starting Y, and Height.
  • Resize — Change the output dimensions using the same coordinate and size fields.

These are the core operations for trimming length and changing the visible frame area.

Rotating, mirroring, and compressing

  • Rotate — Turn the video 90 degrees clockwise or 90 degrees counterclockwise.
  • Mirror — Apply horizontal mirroring or vertical mirroring.
  • Compress — Adjust Video resolution and Video fps, with an Output file size indicator shown as a slider (labeled 0–10M in the page evidence).

Format conversion and output options

The tool supports converting between formats. Output format choices listed on the page include:

MP4, AVI, MPG, MOV, FLV, 3GP, WEBM, MKV, WMV, GIF, plus presets labeled Apple Video and Android Video.

Supported input formats listed on the page are: MP4, WEBM, MOV, FLV, 3GP, M4V, MPG, MPEG, MKV, AVI, WMV, MV, DV, ASF, 3G2.

Encoder and audio settings

When converting, you can set:

Setting Options listed
Video encoder H.264, MPEG-4

Resolution and frame-rate presets

Presets cover common resolutions at 25p, 30p, or 60p:

  • HD 1080p (1920x1080)

  • TV (640x480)
  • Mobile (320x240)

You can also set Video bitrate, Resolution, and Video fps manually.

How to use it

The site describes four steps for processing a video file. The first is to open the video file, and the page advises checking the supported file formats before starting. From there you choose an operation (cut, convert, rotate, mirror, compress, resize, crop), configure the relevant settings, and set the output format.

What to keep in mind

  • The page states files do not need to be uploaded to a server, which is the basis for its security claim — this is a design description from the site, not an independent audit.
  • The page evidence does not list pricing, account requirements, or file-size limits, so those are not confirmed here.
  • Feature availability depends on the format and settings you choose; for example, GIF output and audio-encoder options may not apply to every combination.
