Media Tools

TextGround's media tools cover the complete video and audio workflow — from inspecting a file's codec and bitrate, to trimming, cropping, merging, and converting video and audio — all running locally in your browser via FFmpeg WebAssembly and the Web Audio API.

No files are uploaded to any server. Processing speed depends on your device; large files (several GB) process more slowly but work on most modern laptops and desktops.

Frequently Asked Questions

How are video and audio files processed without uploading?

The video tools use FFmpeg compiled to WebAssembly (FFmpeg WASM), which runs entirely in your browser tab. Your file is loaded into browser memory, processed by FFmpeg, and the result is made available for download — no data travels over the network.

Why is video processing slow?

Video encoding is computationally intensive. Browser-based FFmpeg is several times slower than a native installation because WebAssembly cannot fully exploit multi-core parallelism. For large files (>500 MB) or long videos (>30 minutes), expect processing times of several minutes.

What is the difference between Add Audio, Remove Audio, and Extract Audio?

Add Audio puts a new audio track onto a video. Remove Audio takes the sound out of a video (producing a silent clip). Extract Audio saves the audio track as a standalone audio file. These are three distinct operations — use the one that matches your goal.

What video formats are supported?

Most tools accept MP4 (H.264/H.265), WebM (VP8/VP9), MOV, and AVI. Exact support varies per tool — check the format chips on each tool's page. Output is typically MP4 for maximum compatibility.
