Frequently asked questions
Are the tools really free?
Yes. Every tool is free to use with no sign-up and no watermark. Each tool has a daily allowance that resets at midnight UTC.
Do I need to create an account?
No. Open a tool and start working. There is nothing to install and no account to create.
Are my files uploaded to your server?
Almost never. Images, PDFs, QR codes, JSON, XML and schema markup are made inside your browser, so your files stay on your device. Only File Comparison sends the two texts to our server to work out the differences, and they are not saved.
Do the tools work on my phone?
Yes. Every tool works in the browser on phones, tablets and computers, on Windows, macOS, Linux, Android and iPhone.
Which languages is DeviTools available in?
English, Spanish, German and French. Switch with the language menu at the bottom of every page.
