Your file goes nowhere.
The tool comes to it.
Most “free online” tools send your file to their server, work on it there and send it back. AroraTools turns that around: the page brings the tool to your browser, and your phone or computer does the work.
Our servers never see your files — there is nowhere for them to be stored, leaked or sold.
- 01
You add a file
It opens inside this browser tab, the same way a photo opens in your gallery.
- 02
Your device does the work
Compressing, merging or converting runs on your own processor. No queue, no upload bar.
- 03
You save the result
The new file goes straight to your downloads. Close the tab and it’s gone from the page.
The short answers people ask for most. Each tool page has its own questions too.
Good to know
Are AroraTools really free?
Yes. Every tool is free to use with no account, no daily limit and no watermark on your files.
Do you upload or keep my files?
No. The tools run inside your browser, so your files are processed on your own phone or computer and are never sent to us.
Do the tools work on my phone?
Yes. Every tool is designed for small screens first and works in Safari, Chrome, Firefox and Edge.
Do I need to install anything?
No. Every tool runs in the web browser you already have. There is no app, extension or download to install.
What if the tool I need is not here yet?
New tools are added regularly — the tool gallery shows the ones being built now. Use the search to check what is ready.
Who makes AroraTools?
AroraTools is made by AroraLabs, a small studio that builds apps and web tools.
Got a file to fix?
Pick a tool, drop your file in, download the result. It never leaves your device.
