About Compresor de vídeo

OptiPix Video Compressor lets you reduce video file sizes without uploading them to any server. Using the browser's built-in MediaRecorder API combined with Canvas-based frame processing, videos are re-encoded at lower bitrates while maintaining reasonable visual quality. This is especially useful for compressing videos before sharing on WhatsApp, email, or other platforms with strict file size limits. The compressor supports MP4, WebM, and MOV input formats and outputs optimized WebM or MP4 files. You can adjust the target quality to find the right balance between file size and visual fidelity. Since everything runs in your browser, there are no upload wait times, no file size restrictions from servers, and complete privacy — your videos stay on your device throughout the entire process. Processing speed depends on your device's hardware, with modern computers handling most videos quickly.

How It Works

The compressor uses the browser's MediaRecorder API to re-encode video frames at a lower bitrate. Each frame is drawn onto a Canvas element and re-captured as part of a new media stream, which is then encoded into the output format at your specified quality level.

Use Cases

•Compress videos for WhatsApp's 16 MB file size limit
•Reduce video sizes before attaching to email
•Prepare videos for social media upload with size restrictions
•Free up device storage by compressing archived videos
•Optimize video content for web embedding

Frequently Asked Questions

What video formats are supported?

The compressor accepts MP4, WebM, and MOV files as input. Output is available in WebM format, which offers excellent compression ratios.

Is there a file size limit?

Since processing happens in your browser, there is no server-imposed file size limit. However, very large files (over 500 MB) may be slow to process depending on your device's memory and processing power.

How much can videos be compressed?

Compression ratios vary by content, but typical reductions range from 30-70% depending on the original encoding and your quality settings.

Will compressing my video reduce quality?

Some quality reduction is inherent in re-encoding, but at moderate settings the difference is minimal for most use cases like sharing on social media or via messaging apps.

Does this work on mobile?

Yes, though processing large videos on mobile devices may be slower and consume more battery than on desktop computers.
