Contact PdfKit
One address, read by a person.
Write to tool-kits@outlook.com. It is the only address, and it reaches the people who build PdfKit. There is no form to fill in.
What to write about
A tool that gave a wrong answer, a page that will not load, a translation that reads badly, something you wish existed, or a question about how any of it works. For a problem, naming the tool and the browser is usually enough to find it.
Who runs PdfKit
PdfKit is one of the Tool-Kits sites, a small family of free browser tools. Everything runs on your own device, there are no accounts, and the sites are paid for by the ads on them. Every message is read, though a reply can take a few days.
