Frequently asked questions
Is Time Converter free to use?
Yes. Time Converter is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does Time Converter upload your file to a server?
No. Time Converter processes your file inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.
Is there a file size limit?
The practical ceiling is your device's available memory rather than a server quota. Files up to roughly 100 MB work comfortably on a typical laptop in Time Converter.
Do I need to install anything to use Time Converter?
No installation is needed. Time Converter runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use Time Converter on a phone or tablet?
Yes. The Time Converter interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.
What happens to your file when I close the tab?
It is discarded. Time Converter keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
