Wat is Video Comprimeren?
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.

Veelgestelde vragen
▶Welke videoformaten worden ondersteund?
Je kunt MP4-, WebM-, MOV-, AVI- en MKV-bestanden comprimeren. De uitvoer is altijd in MP4-formaat.
▶Wordt mijn video geüpload naar een server?
Nee! Alles wordt lokaal verwerkt in je browser. Je video verlaat nooit je apparaat.
▶Wat is de maximale bestandsgrootte?
We raden aan bestanden onder de 500MB te houden. Grotere bestanden kunnen mislukken vanwege browsergeheugenlimieten.
▶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.
