Free video tools that never upload your files
Toolvy’s video tools handle the everyday jobs — convert a format, compress a clip to fit an email, trim a section, crop for Instagram, make a GIF, pull out the audio — without uploading anything. They run on ffmpeg compiled to WebAssembly, inside a Web Worker on your own machine, so your footage never leaves your device. We are honest about the trade-off: a browser uses one CPU core, so this is slower than a desktop app and suits short-to-medium clips. You can always cancel, and the tools warn you before a very large file.
The engine downloads once (about 10 MB) on your first file interaction and is then shared with the audio tools for the rest of your visit. Nothing loads until you pick a file — opening this page downloads none of it.
Convert, compress and share
Use the video converter for any format, or a dedicated page like MOV to MP4 for iPhone footage on Windows. To email a clip, the compress-to-target-size tool hits a number like under 25 MB. Pull a soundtrack out with video to MP3 and refine it in the audio tools, or turn a clip into a GIF. Need captions? Generate them from speech with audio to text.
