![]() Upload any file to compress or reduce its size. Kapwing supports MP4, MOV, MP3, FLV, AVI, WebM, and website links. This online video compressor is the best way to compress files, regardless of where you need to use them - it works for email, social media, Google Slides, Discord, just to name a few. You can continue editing by cropping and trimming clips, adding text and image overlays, adding subtitles and credits, combining videos with audio, and much more. Its all-in-one video editor supports all of these workflows while also offering 100+ editing tools. But Kapwing isn’t just a video compressor. Once you’ve selected how compressed you want your video, you can choose to convert it to a different file type or select a new video resolution to ensure the best quality possible. Just choose the video resolution and compression levels you want, and the compressor will balance size and quality. With Kapwing’s video compressor, you can compress video while still having a good final product. Unfortunately, many tools that reduce file size will also impact the video quality. To choose this option, choose "Re-size video" from "Advanced Settings" above.Oftentimes when we’re trying to share our content with others online, we’re hit with a pop-up window notifying us that we’ve exceeded our file size limit- sometimes as small as 8 MB. For example, if you have a 4K (4320p) video but your target device is 1080p, you can downsize the video to fit 1080p and save file size. 4: Make Video Size Smaller (Re-Size)Ĭhoosing a smaller video resolution (dimensions) can also save file size. For more info: read video bitrate control. To choose this option, select "By Max Bitrate" from the "Video Compress" dropdown. Select this method if you are using the video in a streaming application where you want to control the streaming bandwidth rate. The quality is set by CRF (constant rate factor). ![]() This method allows you to set the max bitrate for given video quality. This is the default video compression method used. Increase the target size if you need better quality. To overcome this, start with a decent size (as a percentage of original), then test for video quality. The downside is you don’t know how the target size will affect video quality. The pros of this method are, you can achieve a certain target size. For example, if you set it to 60% for a 1Gb file, we will attempt to make your compressed file size 600Mb or less. This method allows you to set a target file size for your video as a percentage of the original size. As a Percentage of the Original Size (Default) ![]() If you prefer a lower file size over encoding time, choose a slower preset. Choosing a slower preset allows better optimization (lower bitrate/file size) for a given video quality level. Preset: Presets refers to the video compression speed. Higher values mean more compression (reduced file size), lower values mean better quality (but bigger file size). For the H264 encoder, possible CRF values range from 0 to 51. To do that, it uses different compression levels on different frames. By Video QualityĬRF (Constant Rate Factor): CRF method attempts to keep a constant perceived video quality. We provide 4 settings related to both methods. You can either optimize the bitrate or resize the video to a smaller size. There are two main methods to compress a video.
