Cos'è Video Compress?
The Video Compressor reduces video file sizes while maintaining visual quality, making them easier to share via email, messaging apps, and social media. Video files are often too large for direct sharing — a single minute of 4K video can exceed 300MB. Video compression works by removing redundant visual information and optimizing encoding parameters. Modern codecs like H.264 and H.265 can achieve 50-90% size reduction with minimal perceptible quality loss, especially for content viewed on mobile screens. This tool processes videos entirely in your browser using WebAssembly-based encoding. No server uploads required — your videos stay private on your device. Adjust quality settings to find the perfect balance between file size and visual fidelity for your needs.

Domande frequenti
▶Quali formati video sono supportati?
Puoi comprimere file MP4, WebM, MOV, AVI e MKV. L'output è sempre in formato MP4.
▶Il mio video viene caricato su un server?
No! Tutto viene elaborato localmente nel tuo browser. Il tuo video non lascia mai il tuo dispositivo.
▶Qual è la dimensione massima del file?
Consigliamo di mantenere i file sotto i 500MB. File più grandi potrebbero fallire a causa delle limitazioni di memoria del browser.
▶How much can video files be compressed?
Typical compression reduces file size by 50-80% depending on the source video and quality settings. A 100MB video can often be reduced to 20-40MB with no visible quality difference at normal viewing sizes.
▶Does compression affect video quality?
Some quality loss is inherent in lossy compression, but at moderate settings it's imperceptible to most viewers, especially on mobile screens. Higher compression ratios produce smaller files but with more visible artifacts in detailed scenes.
▶What video formats are supported?
The tool supports common formats including MP4, WebM, and MOV as input. Output is typically MP4 with H.264 encoding, which is universally compatible across all devices, browsers, and social media platforms.
