Contact
Write to contact@timfx.de.
There is no contact form here, deliberately. A form would mean collecting and storing what you typed, which sits awkwardly with a site whose entire premise is that it collects nothing.
Reporting a problem with a tool
The most useful report includes your browser and version, your operating system, what you were trying to do, and what happened instead.
Please do not send us the file. We cannot accept it — there is no upload path anywhere on this site, and receiving your file by email would undo the reason you chose LocalFile Tools in the first place. The file’s format, its rough size and its dimensions are enough for us to reproduce almost anything.
Suggesting a tool
Worth knowing what the constraint is: anything suggested has to run entirely in the browser. If a tool cannot work without a server, it will not be built here, however useful it might be.
Privacy questions
The privacy policy covers what is collected and how to withdraw consent, and how it works explains how to verify the no-upload claim yourself. If neither answers your question, write and ask.
