What file formats and sizes does Video Compressor support?

Video Compressor accepts MP4, MOV, WEBM, MKV, AVI (.mp4, .mov, .webm, .mkv, .avi, .m4v). The maximum file payload is 100 MB. Operations are optimized for focused single-file precision.

Does Video Compressor protect my privacy and data?

Yes. All transfers are protected with end-to-end TLS encryption. Your file is processed in an isolated ephemeral sandbox and permanently deleted within 60 minutes. ToolSphere never stores, inspects, or trains AI models on your files.

What makes ToolSphere's Video Compressor better than other free alternatives?

Bypasses Discord, Slack, and email video attachment size limits without turning video into a blurry mess. Unlike legacy cloud converters like iLovePDF or Smallpdf, ToolSphere never limits your daily usage, imposes artificial queue delays, or locks essential export options behind subscription paywalls.

Can I use Video Compressor on my mobile phone or tablet?

Yes. Video Compressor is fully responsive and touch-optimized. It runs smoothly on iPhone (Safari), Android (Chrome, Firefox), iPad, tablets, and desktop operating systems (macOS, Windows, Linux) without requiring any software installation or extensions.

Does Video Compressor add watermarks or require an account?

No. All results produced by Video Compressor are 100% clean with zero watermarks, brand logos, or visual stamps. No signup or account creation is required—you can use the tool immediately and anonymously.
