How to Compress Video Online?

Reduce video file size significantly while maintaining high visual quality. Our tool supports MP4, plain, MOV, MKV, and more.

1

Upload Video File

Select your video file (MP4, AVI, MOV, etc.) from your device. Drag and drop is supported for quick access.

2

Select Compression Mode

Choose 'Best', 'Balanced', or 'Max' compression. 'Balanced' is recommended for the best trade-off between size and quality.

3

Compress & Download

Click 'Compress Video' to start. Once processed, you'll see the file size reduction and can download the optimized video.

Pro Tip: Which Mode to Choose?

Use Balanced (CRF 23) for most web sharing needs—it cuts size by ~40-50% with almost no visible loss. Use Max for emails or WhatsApp where size matters most. Use Best for archiving.

Engineering Philosophy

Smart Compression.
Zero Quality Compromise.

Video compression shouldn't be a trade-off between size and quality. At RiseConvert, we've engineered a context-aware compression algorithm that analyzes every frame of your video.

By leveraging FFmpeg's advanced CRF (Constant Rate Factor) technology, our engine identifies areas of high visual complexity and allocates more bitrate there, while saving space in less complex scenes. The result? Videos that look identical to the source but are up to 80% smaller.

We process everything in a secure, ephemeral environment. Your videos are processed in isolated containers that are completely destroyed after your session, ensuring absolute privacy for your personal or professional content.

Why Compress Videos?

In today's digital world, video is king, but large video files are the enemy of speed and storage. High-resolution videos (4K, 1080p) can take up gigabytes of space, making them difficult to share via email, Slack, or upload to social media platforms.

Video compression is the process of encoding a video file to consume less space than the original file, while maintaining a level of visual quality. RiseConvert uses advanced algorithms to remove redundant data from your video streams, ensuring your content remains crisp while reducing the file burden.

Understanding CRF (Constant Rate Factor)

Most simple video compressors just lower the bitrate blindly, which often results in "blocky" or pixelated videos. RiseConvert uses CRF technology.

Instead of targeting a specific file size, CRF targets a specific quality level.

  • Scene Analysis: It analyzes each frame. Simple scenes (like a talking head against a plain wall) need less data. Complex scenes (like an explosion or running water) need more.
  • Smart Allocation: It saves bits on simple frames and spends them on complex ones, keeping the quality consistent to the human eye.
  • Settings: Our "Best Quality" corresponds to a lower CRF value (higher bitrate), while "Max Compression" uses a higher CRF value (lower bitrate).

Essential Video Terms

Bitrate

The amount of data used to represent one second of video. Higher bitrate usually means better quality but larger file size.

Codec

The technology used to compress and decompress video data. We primarily use H.264 (AVC) for maximum compatibility.

Resolution

The number of pixels in each frame (e.g., 1920x1080). Reducing resolution is another way to shrink file size.

Frame Rate (FPS)

The number of individual images displayed per second. Standard rates are 24, 30, and 60 fps.

Container

The file format holding the video, audio, and metadata (e.g., .mp4, .mov, .mkv).

Artifacts

Visible distortions in a video (like blockiness) caused by aggressive compression.

Common Issues & Solutions

Compression Too Aggressive

If your video looks pixelated or blocky, try using the "Best Quality" or "Balanced" mode instead of "Max Compression".

File Size Didn't Change Much?

If the source video was already highly compressed, further compression might not reduce size significantly without ruining quality.

Best Format

We output to MP4 (H.264), which is universally supported. This fixes compatibility issues with MOV or MKV files.

Frequently Asked Questions

Is RiseConvert Video Compressor free?
Yes, it is completely free to use for files up to 500MB. We do not watermark your videos. For larger files or bulk processing, we offer premium plans.
What video formats do you support?
We support a wide range of input formats including MP4, AVI, MOV, MKV, WMV, FLV, and WEBM. The output will always be optimized MP4 (H.264) for maximum compatibility.
How much will the file size be reduced?
It depends on the original video's complexity and the compression mode you choose. 'Balanced' mode typically reduces file size by 40-50%, while 'Max Compression' can achieve up to 70-80% reduction.
Will I lose video quality?
Our goal is to be 'visually lossless'. This means we remove data that the human eye can't easily perceive. In 'Best' and 'Balanced' modes, the quality difference is usually negligible to the naked eye.
Is it safe to upload my personal videos?
Absolutely. We use secure HTTPS connections for uploads. Your videos are processed in isolated containers and are automatically deleted from our servers shortly after processing. We do not access, view, or share your content.
Can I compress 4K videos?
Yes, we support 4K video compression. However, please note that processing 4K videos requires more computational power and may take longer to complete.
