- Performance: Speed depends on your CPU.
- Secure: Perfect for sensitive documents.
- GPU Acceleration: Fast compression with hardware support.
Is my video uploaded to a server?
Absolutely not. GPTchatly Video Editor runs entirely in your web browser using WebAssembly and WebGPU. Your files remain on your device at all times. This guarantees 100% privacy and security for your data.
Why is conversion slow on my phone?
Because we don't use powerful cloud servers, the speed depends entirely on your device's processor. Mobile phones have less processing power than desktop computers, so complex tasks (like high-quality compression or GIF generation) will naturally take longer.
Do I need to register or pay?
No. There is no registration, no login, and no payment required. The tool is free for unlimited use, and we never add watermarks to your videos.
What editing features are available?
Beyond compression, you can:
• Convert to GIF with high-quality palettes.
• Trim & Crop unwanted footage.
• Rotate & Flip to fix orientation.
• Add Cover Image to set a custom thumbnail.
Presets vs. Target Size?
Presets (Fast/Balanced) use "Constant Rate Factor" technology to guarantee a specific visual quality, allowing the file size to vary naturally.
Target Size is a calculator: you pick a limit (e.g., "8MB" for Discord), and we mathematically determine the exact quality settings to fit your video into that size.
What formats do you support?
We accept virtually any video format including MP4, MOV, MKV, WebM, AVI, WMV, and FLV.
We export to universally compatible MP4 (H.264/AAC) or GIF, ensuring your content plays perfectly on iPhone, Android, Windows, Mac, and all social media platforms.
How does AI Upscaling work?
We use advanced neural networks (e.g., Real-ESRGAN) running directly in your browser via WebGPU.
This AI analyzes each frame to hallucinate missing details, allowing you to convert sticky 1080p footage into sharp 4K video without uploading massive files to a cloud server.
How does GPU Acceleration help?
We tap into your computer's Graphics Card (GPU) to compress video significantly faster than using the CPU alone.
This hardware-accelerated encoding is modern, efficient, and keeps your computer responsive while processing large 4K files.
