Free Video Size Reducer – How to Reduce Video File Size to 90%

[Video Processing] How to Reduce Video Size with a Free Video Size Reducer for Windows 10 or Mac?

- I have acquired many broadcast TV AVCHD Video (.mts) files that I have recorded using my Proscan "over-the-air" digital converter box. The trouble is that an hour's worth of HD programming uses up about 5 to 6G's of space on my flash drive. That is a lot space to store a single 1 hour program! Most of the programs that I record are news documentaries and high definition viewing is not an important factor for me. I have looked at the free video size reducer like 'Handbrake' software on-line and it appears that they may have a file input size limitation or take an extremely long time to reduce a large file.

The article will show you how to reduce 4K/HD video size easily with a free video reducer on Windows (7-10) or Mac. You may be interested in how many KBs or percentage will the free video compressor cut from the original video, how about the video quality after resizing. These questions will be answered later in the article. Before that, you are suggested to download the free video reducer first.

How Much Can the Free Video Size Reducer Compress a Video?

Here I'd like to show you how WinX Video Converter can reduce a video file size through two genuine tests on Windows 10 computer.

Test 1:
Source Video: Sintel (2010) MKV video
Computer: Windows 10 Pro (64 bit)
Processor: Intel® i5-3470 CPU @ 3.20GHz 3.60 GHz;

  • Input

  • Output

  • File size
  • 643 MiB

  • 62.5 MiB

  • Duration
  • 14mn 48s

  • 14mn 48s

  • Format
  • MKV

  • MKV

  • Overall Bit Rate
  • 6071 kb/s

  • 591 kb/s

  • Width
  • 1280 pixels

  • 1280 pixels

  • Height
  • 544 pixels

  • 544 pixels

  • Display Aspect Ratio
  • 2.35:1

  • 2.35:1

  • Frame Rate
  • 24.000 FPS

  • 24.000 FPS

  • Audio Channels
  • 6 channels

  • 2 channels

• Compression ratio: OVER 90%!!!
As you can see from the test, without even lowering frame rate, trimming / cropping video, or removing audio from video, the output file length is only 1/10 of the original video.

Our Verdict: HEVC is a good compression codec for video size reduction.

Test 2:
Source Video: The Revenant (2015) AVI movie video
Computer: Windows 10 Education (64 bit)
Processor: Intel(R) Core(TM) i5-4460 CPU @ 3.20GHz, 3201 Mhz, 4 Core(s), 4 Logical Processor(s)

  • Input

  • Output

  • File size
  • 2.05 GiB

  • 331 MiB

  • Duration
  • 2h 36 min

  • 2h 25 min

  • Codec
  • XVID

  • HEVC

  • Overall Bit Rate
  • 1880 kb/s

  • 318 kb/s

  • Width Height
  • 720 pixels

  • 720 pixels

  • Width Height
  • 304 pixels

  • 304 pixels

  • Display Aspect Ratio
  • 2.35:1

  • 2.35:1

  • Frame Rate
  • 23.976 FPS

  • 23.976 FPS

Without changing video resolutions as well as fame rate, the compression ratio of converting an AVI video to MP4 (HEVC) video is about 84%, the quality of output video file will be well kept, and no obvious video degradation is noticeable.

• Our Verdict: MP4 has better compression ratio than AVI. That is to say, if at the same file size (or bit rate), an MP4 video will have a better quality than an AVI video. Read: AVI vs MP4 >>

Desktop Video Size Reducer vs Online Video Compressor

In fact, several so-called online video size reducers are not real; they are just Google Ads oriented for SEO goal. The real online video compressors all have file input size limitation or take an extremely long time to compress a large file.

VideoSmaller – 500MB limit for input, need to download My Quick Converter app to your browser.
Clipchamp – email registration is required. You can't return to the previous page after entering the registering window. It has watermark. Webcam recording is limited to 5 min.
Aconvert: 200MB limit for input. It is actually an online video converter, instead of an online video compressor.
