Get in Touch with DotFixer
DotFixer is an independent, ad-supported site, so there is no support queue here — just an inbox that a real person reads. The messages that help us most are the concrete ones: a number in a calculator that looks wrong, a formula you would explain differently, or a tool you wish existed. That feedback is how the Data Storage Unit Converter, Download Time Calculator, PSU Wattage Calculator, IP Subnet Calculator, Screen Resolution & PPI Calculator, and Password Strength Checker get better over time.
Write to us at admin@dotfixer.com. We read everything, though as a small site we cannot promise a fixed reply time and may not answer every message individually. If you are reporting a problem with a tool, it helps to include your browser and device, the numbers you entered, and what you expected to see — that alone is often enough for us to reproduce and fix it.
One thing we cannot do
We cannot diagnose or repair your specific machine over email. DotFixer publishes calculators and general guides, not a hands-on repair service, and results are estimates rather than professional diagnostics. For a computer that will not boot, a failing drive, or anything holding irreplaceable data, please back up first and consult a qualified technician. For background reading in the meantime, the blog and learn section cover many of the questions that bring people here.
