Questions
Are my files uploaded anywhere?
No. On-device tools run in your browser and we keep no server copy of your files. A few tools have an online feature, such as fetching a web page, and those are tagged "uses the internet". Each one has a notice about what it sends.
Do I need an account?
No. Every tool is usable the second the page loads, with no popups or click-through walls.
What does the site remember?
Last-used settings per tool, your recently used tools, your theme choice and up to 8 favorites, all in your own browser. The Saved data page shows what is stored and lets you clear it.
How do I find tools that stay fully on my device?
Open the directory and tick "On-device only". It hides every tool that has an online feature.
Can I use the tools offline?
Once a tool page has loaded, most tools keep working without a connection, because the processing happens in your browser. The few tools with an online feature need a connection for that feature only.
Is there a file size limit?
We set no limit of our own. The practical limit is your device's memory, so very large videos or PDFs may be slow on older phones and laptops.
Does it cost anything?
No. Every tool is free to use, with no trial period and no watermark on your results.
Which browsers work best?
Current versions of Chrome, Edge, Firefox and Safari. A few heavier tools, such as video, run fastest on a desktop browser.
Can I clear what the site has saved?
Yes. The Saved data page lists what is stored in your browser, including settings, favorites and your recently used tools, and clears it with one click.
Do you know which tools I use?
No. Everything runs on your device, so we do not see which tools you open or what you do in them. Your favorites and Recently used list live only in your own browser.
