The problem we solve
A small file task should not require an account, a large application or uploading a private document. JustFileKit turns common workflows into focused tools and explains input limits, output formats and important quality trade-offs on the relevant page.
How files are processed
Core file processing runs in the browser. File contents are not sent to JustFileKit servers, and temporary browser data is no longer retained after the tab is refreshed or closed. Tool pages explain when a process re-encodes, rasterizes or changes selectable text.
Who maintains the site
The site and its content are maintained by the JustFileKit Editorial Team. Technical changes and corrections can be followed in the public GitHub repository. Financial calculators identify their review date, method, scope, limitations and official sources. The site does not represent a government agency, lender or professional adviser.
Revenue and independence
JustFileKit may show advertising on pages with substantial publisher content to support operating costs. Advertising does not change formulas, tool outputs or editorial conclusions, and advertisers do not receive the files users process.
