5 Best Ways to Reduce Video Size Online without Losing Quality for Free

Best Video Quality Setup for Reducing Video Size

Before we move to the free online video compressors to scale down your video file, let's briefly discuss the classic video qualities and technical aspects that define the physical size of your video file.

Classic Video Quality, Resolution and Aspect Ratio:

  Official Name Pixel Size (width & height) Aspect Ratio
8k or 4320p 8k video (Full Ultra HD) 7680 x 4320 16:9
4k or 2160p 4k video (Ultra HD) 3840 x 2160 1:1.9
1440p QHD (Quad HD) 2560 x 1440 16:9
1080p (recommended) Full HD 1920 x 1080 16:9
720p HD (High Definition) 1280 x 720 16:9
480p SD (Standard Definition) 852 x 480 16:9

To reduce the file size of 4k or 8k videos while still retaining their video quality, it's highly recommended to scale down the video resolution to 1920 x 1080p (Full HD) or 1280 x 720p (HD) because these two video qualities promise the best viewing experience online and compatible with the all online video hosting platforms.

So, in addition to the video resolution (like 4320p, 2160p or 1080p, 720p, or the number of pixels used to form a video image), what else defines the physical size of a video file? Well, there are 4 more elements:

  • Bitrate: Bitrate refers to the amount of digital information transferred into audio and video per second, or also known as bit/s. The higher the bitrate, the bigger the video size and better video quality. For example, a 1080p video has 8Mbps while a 720p video has 5Mbps.
  • Frame Rate (or FPS): A video actually consists of tons of images. And the frame rate determines how many images are shown consecutively per second. The higher the frame rate, the smoother the video and the bigger the file size. For example, most films and TV series are shot with 24 FPS.
  • Encoding and Encoder: Imagine that a video is a car and the video resolution, bitrate, frame rate, etc. would be different auto parts while the encoding and encoder should be the chassis and frame of the video. The commonly seen encodings are H.264, H.265 and the encoders are MP4, MOV, and AVI, etc.
  • Recommended Video Quality Setup:

    Video format(encoder): MP4 (across platforms)

    Video resolution: 1080p; 720p

    Bitrates: 8M for 1080p video; 5M for 720p video

    Frame Rate: 24-30 FPS

    Encoding: H.265

    Compared with H.264 encoding, H.265 is specially made to generate high-resolution video and it offers between 25% and 50% more data compression at the same level of video quality.
