Need help?How to Compress Xvid Video
- Upload Your Xvid File — Click "Choose Files" or drag and drop your Xvid video file. Only .xvid files are accepted.
- Choose Compression Method — Under File Compression, the default is Target File Size % (1-100% slider with Smart Scaling). Other options: Quality Preset (Highest through Lowest), Specific File Size (MB/KB), Constant Bitrate, Variable Bitrate, Constant Quality (CRF), or Constraint Quality (CRF + max bitrate).
- Adjust Resolution (Optional) — Under Video Resolution, keep the original or choose Preset Resolutions (1080p, 720p, 480p, etc.), Fixed Resolutions, Resolution Percentage, or custom Width/Height.
- Trim (Optional) — Under Trim, set a Start Time and Duration to remove unwanted sections and reduce file size further.
- Compress & Download — Click "Convert" and download your compressed Xvid file.
Why Compress Xvid Video?
Xvid is an open-source MPEG-4 ASP video codec popular for sharing movies and TV shows. Xvid files can be large, especially at high bitrates. Compressing reduces file size for easier sharing via email or messaging apps, fitting videos onto storage devices with limited space, faster uploads to hosting platforms, and reducing bandwidth usage for streaming.
Compression Methods Explained
| Method | How It Works | Best For |
|---|---|---|
| Target File Size (%) | Slider from 1-100% of original | Predictable size reduction (default) |
| Quality Preset | Automatic quality (Highest→Lowest) | Quick compression without manual tuning |
| Specific File Size | Enter exact MB or KB target | Meeting upload limits (email, Discord) |
| Constant Quality (CRF) | Quality-based encoding | Best quality-to-size ratio |
| Constant Bitrate | Fixed bitrate throughout | Consistent streaming quality |
| Variable Bitrate | Adapts bitrate to content | Efficient compression for varied content |
| Constraint Quality | CRF with max bitrate cap | Streaming with bandwidth limits |
Xvid Compression Tips
| Goal | Recommended Settings |
|---|---|
| Reduce by 50% | Target File Size: 50% |
| Fit under 25 MB (Discord) | Specific File Size: 25 MB |
| Maximum quality | Quality Preset: Highest or CRF with low value |
| Reduce resolution | Video Resolution: 720p or 480p |
| Remove unwanted parts | Trim: set Start Time and Duration |
Will compressing reduce video quality?
Some quality loss is inherent with compression. The amount depends on your settings — Target File Size at 80% produces minimal visible loss, while 30% will show noticeable degradation. Use Constant Quality (CRF) for the best quality-to-size ratio, or Quality Preset at "Very High" for a good balance.
What is the default video codec for Xvid compression?
The default codec is Xvid (MPEG-4 ASP), which keeps the output in the same format. The default audio codec is MP3. You can change both under Video Codec and Audio Codec if needed.
Can I compress and trim at the same time?
Yes. Set your compression method under File Compression, then set trim points under Trim. Both operations are applied in a single pass — trimming alone can significantly reduce file size by removing unwanted footage.
How much can I reduce the file size?
Typical results: Target File Size at 50% produces a file roughly half the original size. Lowering resolution from 1080p to 720p can reduce size by an additional 40-60%. Combining compression with resolution reduction and trimming can achieve 70-90% size reduction.
What is the difference between CRF and Constant Bitrate?
CRF (Constant Quality) adjusts bitrate dynamically to maintain consistent visual quality — complex scenes get more bits, simple scenes get fewer. Constant Bitrate uses the same bitrate throughout, which is predictable but less efficient. CRF generally produces better results at the same file size.
