Compress Video Online - Reduce Size, Keep Quality

Shrink your videos for WhatsApp, Email, or YouTube without installing heavy software. Smart compression that respects your pixels.

1

Select Video

Click 'Select Video Files' to upload MP4, MOV, or any major format. Up to 500MB supported.

2

Choose Quality

Select 'Balanced' for best results or 'Max' for smallest size. We optimize bitrate automatically.

3

Download MP4

Our server crushes the file size in seconds. Download your optimized MP4 instantly.

Why CRF is Better

Most tools drop resolution to save space. We use CRF (Constant Rate Factor) to keep the resolution high (even 4K) but optimize the data behind the scenes, removing redundant information the eye can't see.

Technology

Intelligent Video Optimization

Our algorithms understand motion. We save bits on static scenes and spend them on action.

Space Saver

Free up gigabytes on your phone or computer. Perfect for archiving old videos.

Format Support

We accept almost any video format (AVI, MKV, MOV, FLV) and convert it to a universally compatible compressed MP4.

Fast Processing

No software to install. Our powerful backend processors handle the encoding load instantly.

Secure & Private

Processing happens in isolated containers. Files are wiped automatically, guaranteeing your privacy.

Smarter Compression.
Not Just Smaller.

Re-encoding a video often leads to blocky artifacts and washed-out colors. Standard compressors blindly cut the bitrate, hoping for the best. We took a different approach using Constant Rate Factor (CRF).

Our engine analyzes each frame's complexity. If a scene is static (like a talking head), it compresses aggressively. If there is high motion (like a sports clip), it allocates more data to preserve detail. This dynamic bitrate allocation ensures you get the smallest possible file size with perceptually lossless quality.

We leverage powerful Cloud Computing to handle the intense mathematics of H.264/HEVC encoding, freeing up your device's battery and CPU.

Understanding Video Compression

Video compression is the art of balancing visual quality with file size. Raw video captures millions of colored pixels 30 to 60 times a second, resulting in massive files. To store or share this, we need 'Codecs' (Compression-Decompression) algorithms like H.264 (AVC) or H.265 (HEVC).

There are two main types of compression:
1. Lossless: Preserves every bit of data. File size reduction is minimal (maybe 10-20%). Not practical for video.
2. Lossy: Discards data that the human eye is less likely to notice. This is what modern video streaming involves.

Our tool is a Smart Lossy Compressor. It uses psychovisual models to determine which details can be simplified (like the blue sky in a background) and which must be preserved (like fine text or faces).

Video Glossary

Bitrate

The amount of data used per second (e.g., 5 Mbps). Lower bitrate = smaller file but potentially lower quality.

Codecs (H.264)

The standard technology for compressing video. Compatible with 99% of devices.

CRF

Constant Rate Factor. A setting that targets a quality level rather than a specific size/bitrate.

Resolution

The dimensions of the video (e.g., 1920x1080). Reducing this drastically lowers size.

Frame Rate

Frames per second (fps). 60fps video is twice as large as 30fps video.

Muxing

The process of combining video, audio, and subtitles into a single container file (like .mp4).
