Home › File & Tech Utilities
Short answer: ToolVaultly’s file and tech utilities handle the odd jobs around files themselves: bundling files into a ZIP, opening a ZIP without installing anything, pulling the audio track out of a video, and estimating how long a download will really take at your connection speed. The important difference from most file sites: your files are processed on your own device. Nothing is uploaded to a server — which is why there are no size queues and no waiting for an upload bar before the work even starts.
File tools are where upload-first design hurts most: sending a large video to a stranger’s server just to extract its audio wastes your bandwidth and hands over your data. Modern browsers can do these jobs locally, and that is how every tool on this page works — the file you drop in never leaves your machine.
The hub is small but the jobs are universal. If your file is a document rather than an archive or a video, the PDF and image hubs linked below cover editing, converting and compressing those.
Which file utility do you need?
Sending several files as one? Create ZIP online bundles them in your browser. Received a ZIP you cannot open? Unzip files online extracts it with no software to install. Need just the sound from a clip — a lecture, a song from a video, a voice note? Extract audio from video pulls the track out locally. And before a big download, the download time calculator turns file size and connection speed into an honest estimate, so you know whether to start it now or overnight.

Frequently asked questions
Do my files get uploaded to a server?
No. Every tool on this page runs in your browser using your device’s own processing. Your files are never uploaded, stored or seen by anyone — you can test it by loading a tool, going offline, and using it anyway.
Is there a file size limit?
There is no server limit because there is no server. Practical limits come from your device’s memory — very large videos can strain a low-end phone, but typical files, including long clips and big archives, work fine on ordinary hardware.
What formats can I extract audio from?
The
extract audio from video tool reads the common web and phone formats (MP4, WebM, MOV and similar) and returns a standard audio file. If a video’s audio uses an unusual codec, the tool will tell you rather than fail silently.
How accurate is the download time calculator?
It does the exact arithmetic — file size against connection speed — and shows the effect of overhead. Real downloads vary with congestion, so treat the result as a good planning estimate; the
download time calculator lets you test slower effective speeds to be safe.
Are these file tools free?
Yes — free, no signup, no watermarks and no per-file fees.
