Powered by FFmpeg WebAssembly executed inside your browser sandbox.
Video files are large, private, and computationally expensive. Traditional websites require you to spend minutes uploading hundreds of megabytes to their cloud servers, where your personal videos sit on their hard drives.
ConvertAllNow eliminates this security risk. Our Video Compressor and Video Trimmer run the industry-standard FFmpeg multimedia engine directly inside your browser via WebAssembly (WASM).
Your video bits stay securely in your device’s local memory buffer. Files stay on your device with no server upload wait times.
Our tools support popular container and media formats including MP4, WebM, MOV, AVI, MKV, MP3, WAV, AAC, OGG, and M4A. Specific format playback depends on browser media decoders and WebAssembly FFmpeg support.
You have full control over the compression settings. Our tool uses smart CRF (Constant Rate Factor) encoding algorithms that eliminate invisible high-frequency noise, drastically reducing file size while keeping visual crispness intact.
We utilize FFmpeg compiled directly to WebAssembly (WASM). This allows your browser to run the full power of FFmpeg natively on your computer’s CPU and GPU threads. Your video data never travels over the internet.
Yes. Simply upload your video into our Audio Converter or Video to MP3 tool, choose your desired audio bitrate (e.g. 128kbps, 192kbps, or 320kbps), and the audio stream will be extracted and saved as an MP3 file.
Because video processing occurs entirely in browser memory, practical limits depend on your computer or device’s available RAM. Files up to 500MB–1GB typically process smoothly on modern desktop and laptop systems.
No. Link requests are processed solely to retrieve media streams for the user and are never logged, archived, or associated with your identity.
