How the privacy claim holds up

“Private” is easy to say, so here is what it means on this site. The tools are plain JavaScript that runs on your device. Your text, images and PDFs are read and changed in your browser's memory and never sent to us. To check, open developer tools, go to the Network tab, and use any tool: you will see no upload.

The exceptions, so nothing surprises you:

Questions

Are my files uploaded anywhere?
For almost every tool, no. Text, images, PDFs and code are processed by JavaScript in your own browser, so the content never reaches our servers. A few tools do need the network (live exchange rates, for example) and are listed in the privacy section above. You can confirm it yourself: open your browser's developer tools, switch to the Network tab, and use a tool. You will see no upload.
Do I need an account, and is there a limit?
No account, no email, and no usage limits. Every tool is free. The site is supported by ads, which is why there is no paywall.
Do the tools work on a phone?
Yes. Every tool is responsive and works on phones and tablets. Some heavy tools, such as PDF merging or HEIC conversion, are faster on a desktop because they run on your device's own processor.
Can I suggest a tool or report a bug?
Yes, use the contact page. Tool requests that come up repeatedly are the ones we build next.
