Video Compressor Online

Compress video files to reduce file size for email, web publishing, and storage. Uses server-side FFmpeg encoding to transcode MP4, MOV, AVI, MKV, and WebM videos up to 90 MB into compact, universally compatible MP4 files.

NewTools Video Compressor reduces the file size of your videos online. Upload a video, choose a compression level, and download a smaller MP4 file — great for email, sharing, and freeing up storage.

How It Works

1

Upload a supported video file

Drag and drop your video into the upload area or click to browse files. Accepted formats: MP4, MOV, AVI, MKV, WebM, FLV, and WMV. Maximum file size is 60 MB.

  • One video is processed at a time
  • Files larger than 60 MB will be rejected before upload
2

Choose available compression options

Select a quality setting — Low (smallest file), Medium (balanced), or High (best quality). The setting you pick affects how much the file is reduced and the output quality.

  • Low: smallest file size, lower quality
  • Medium: balanced quality and file size
  • High: best quality, moderate compression
3

Start the compression process

Click Compress Video and wait for the server to process your file. Compression time depends on the video duration, format, and server load.

  • The video is uploaded to the server for processing
  • Processing time varies by video size and server availability
4

Download the compressed video if available

When processing succeeds, you can download the compressed video. The output is returned as an MP4 file with '-compressed' appended to the filename.

  • Output format is MP4
  • Original and compressed file sizes are displayed for comparison

Common Use Cases

Messaging & Chat Apps

Compress video clips to fit within messaging app limits (such as WhatsApp 16 MB or Discord file caps) without sharing errors.

Email Video Attachments

Reduce recorded video size below standard 20 MB or 25 MB email attachment limits for smooth delivery.

Saving Mobile & Cloud Storage

Shrink personal video recordings to free up valuable storage space on your smartphone, tablet, or laptop.

Tips & Best Practices

Choose the right quality setting

Use Low for maximum file-size reduction when quality is less important. Use Medium for a balance of size and quality. Use High when you need to preserve as much quality as possible.

Check file-size limits first

Files larger than 60 MB cannot be processed. If your video is too large, try trimming the length or reducing the resolution before uploading.

Compression results can vary

The final file size and output quality depend on the source video format, duration, resolution, bitrate, and the quality setting you select. Two videos with the same file size may compress differently.

Video Compressor

Compress videos for any purpose

Whether you need to email a video attachment, share a clip in a messaging app, or free up storage space, compressing your video makes it faster to send and easier to store.

Choosing the right quality setting

Low produces the smallest file but reduces visual quality. Medium balances size and quality — good for most uses. High preserves more detail with moderate compression.

How it works

  • Upload a video file (max 60 MB) in MP4, MOV, AVI, MKV, WebM, FLV, or WMV format.
  • Choose Low, Medium, or High compression.
  • Your video is processed in your browser and returned as MP4.
  • Download your compressed video.

Frequently Asked Questions

Is video compression instant?

No. Video transcoding is computationally intensive. The server must decode each video frame, analyze spatial complexity, and re-encode the stream using H.264 compression. Processing time varies with video length, resolution, and server queue status.

What is the maximum file size?

The primary server compressor accepts video files up to 90 MB.

What happens to the audio in compressed videos?

Audio tracks are preserved using standard AAC encoding, maintaining clear voice and music while minimizing overall file weight.

Which compression level should I choose?

Choose Medium for a balanced blend of reduced file size and good visual quality; choose Low if you need the smallest possible file for email attachments; and High when preserving fine visual detail is critical.

Why did my video compression fail or take longer than expected?

Processing can take longer or fail if the video exceeds 90 MB, uses an uncommon proprietary codec, or if the server queue is experiencing peak demand. Try choosing Medium or Low quality for faster processing.
