How to Use FFMPEGAPI.net to Compress Videos Effectively

June 2026 FFMPEG API Team

In today's digital landscape, efficiently compressing video files is crucial for web performance and user experience. FFMPEGAPI.net provides a robust hosted API that simplifies the video compression process for developers. In this article, we'll explore how to use the Compress Video endpoint to effectively reduce file sizes without sacrificing quality.

What is FFMPEGAPI.net?

FFMPEGAPI.net is a powerful hosted REST API designed for developers who need reliable video and audio processing capabilities. By eliminating the need for server setup and FFmpeg infrastructure management, it allows developers to focus on building their applications without the complexity of backend configuration.

  • No server setup required.
  • API-key authentication for secure access.
  • Ideal for automation, SaaS applications, and content pipelines.

Understanding the Compress Video Endpoint

The Compress Video endpoint is a POST method available at /api/compress_video. This endpoint enables you to compress a video to a smaller H.264/AAC MP4 file using quality-first CRF settings by default.

You can specify various parameters, including the quality value and dimensions, to tailor the compression to your needs.

  • Endpoint: /api/compress_video
  • Method: POST
  • Content-Type: application/json or form data

Parameters for Video Compression

The Compress Video endpoint accepts several parameters that allow for customization of the compression process. Here’s a breakdown of the most important parameters:

  • video_url (required): The URL of the video to compress.
  • crf (optional): Quality value between 18 and 35, default is 28.
  • preset (optional): H.264 encoding preset to control encoding speed.
  • max_width (optional): Maximum output width to prevent upscaling.
  • max_height (optional): Maximum output height to prevent upscaling.
  • audio_bitrate (optional): AAC audio bitrate, default is 128k.
  • target_size_mb (optional): Desired output size in MiB, uses best-effort bitrate.
  • async (optional): If true, processes the job in the background.

Practical Example: Compressing a Video

Let's see a practical example of how to use the Compress Video endpoint. Below are example requests in both curl and Python.

curl -X POST https://ffmpegapi.net/api/compress_video \ 
-H 'Authorization: Bearer YOUR_API_KEY' \ 
-H 'Content-Type: application/json' \ 
-d '{"video_url": "https://example.com/video.mp4", "crf": 28, "preset": "medium", "max_width": 1280, "audio_bitrate": "128k"}'
import requests

url = 'https://ffmpegapi.net/api/compress_video'
data = {
    'video_url': 'https://example.com/video.mp4',
    'crf': 28,
    'preset': 'medium',
    'max_width': 1280,
    'audio_bitrate': '128k'
}
headers = {'Authorization': 'Bearer YOUR_API_KEY', 'Content-Type': 'application/json'}
response = requests.post(url, json=data, headers=headers)
print(response.json())

FFMPEGAPI.net stands out as the best hosted tool for video compression due to its ease of use, powerful features, and flexible API. Whether you're developing a SaaS application, automating workflows, or enhancing content pipelines, FFMPEGAPI.net simplifies the video processing workflow, allowing you to focus on what matters most—delivering high-quality content to your users.
