Frequently Asked Questions
Is MediaPix really free?
Yes, 100% free with no hidden fees, no premium tiers, and no usage limits. Every tool is available to everyone without creating an account.
Are my files uploaded to a server?
No. All processing happens locally in your browser using FFmpeg compiled to WebAssembly. Your files never leave your device — we literally cannot see or access them.
What browsers are supported?
MediaPix works on all modern browsers including Chrome, Firefox, Safari, and Edge. It requires WebAssembly support, which is available in all browsers released since 2017.
Is there a file size limit?
There is no hard limit. Processing very large files (over 2GB) depends on your device's available RAM. For best performance, we recommend files under 500MB.
Can I use MediaPix on my phone?
Yes! MediaPix works on mobile browsers. However, video processing is resource-intensive, so performance may vary depending on your device. For large files, we recommend using a desktop or laptop.
How does browser-based processing work?
MediaPix uses FFmpeg compiled to WebAssembly (Wasm), a technology that allows native-speed code to run directly in your browser. This means you get the power of FFmpeg without installing any software.
