Depending on the compression codec, that loss can be non-existent, minimal, or pretty noticeable. The downside, however, is a loss in quality since video compression requires data to be deleted. Most file transfer services like WeTransfer, Dropbox, Gigafile, Datadeliver and Firestorage have strict file size limits which force users to seek out compression in the first place. It helps get around the often-frustrating file size limitations of many file transfer and email platforms. This is done automatically by an algorithm, which parses the video file and searches for any data that can be removed without (hopefully) corrupting the overall file.Ĭompressing video files can be incredibly useful when sending raw footage or particularly large video files to collaborators, partners, and clients. In short, video compression is the act of reducing video file size by lowering its resolution and bitrate. 100 native code was used, we do not use FFMPEG as it is very slow, bloated and the GNU license is an obstacle for commercial applications. In addition, this software uses a static build from the FFmpeg project ( FFmpeg static build and FFmpeg source) under the LGPLv2.1 (GNU Lesser General Public License). Compress videos, remove audio, manipulate thumbnails, and make your video compatible with all platforms through this lightweight and efficient library. Finally, if you want to customize output video dimension or aspect ratio, you can use "Scaling" option, video dimension (width and height) must be divisible by 2, the supported aspect ratios include 4:3, 1:1, 16:10 and 16:9.īy using this small tool, you can easily decrease your video file size by yourself, it can help you to save disk space, and share video clips with your family and friends on the Internet, or view these videos on your mobile phones and other handheld devices. Secondly, by using "Cutting" options, you can choice a part of video, set a start time and an ending time, you can easily convert and compress a part of video. Firstly, you can change output audio bit rate, because audio content will occupy some file space, you can set a smaller bit rate to reduce file size, or simply set audio quality as "No Sound", then output file will only include video content (silent). The encoding video quality is based output file size, output file size is more bigger and resulting video quality is more higher and more clearer.įurthermore, in order to get a smaller result, software also supports some useful compression options. The generated video format is MP4 container format with H.264 video codec and AAC audio codec. (Bitrate information is displayed as KB/S, KB/S = kiloBits/second). This desired video size is approximate value, resulting file may be smaller or larger than this size, you can change this value as you need. After software open a source video, it will read and show key video information, such as: File Size, Bitrate, Duration, Video Format, Video Bitrate, Audio Format, Audio Bitrate and Video Dimension (Width / Height), then software will calculate an estimated output video size, that is "Desired Video Size". The basic usage is very simple, click on "Open" button to select a video file, then set a desired compressed video size, finally, click "Compress" button to start video compression.įirst of all, the most important option is "Desired Video Size". Whether you need to compress a 3 GB video file or a 200 MB one, you can do so in Kapwing. Kapwing supports many video file types, including MP4, MOV, AVI, WebM, WMV, and more. You can select a video file, enter a desired video size, and choose an audio quality to create a smaller video in MP4 format. This software can work with many popular video formats, such as MP4 (MPEG4), MPG, AVI, FLV, F4V, M4V, WMV, MOV, MKV, ASF, RMVB (RM) and more.įreeware, clean and easy to use, free for personal and non-commercial use, get it from a file mirror. The best way to compress a large video file into a smaller one is to use a specialized online video compressor like Kapwing. Compress Video is a free online tool that can help you compress your video files and reduce their file size. Free Video Compressor is a free and lightweight video compression software that can compress almost common video files, it can help you to easily shrink a video clip and reduce video file size.
