Frequently asked questions
Is Weight Converter free to use?
Yes. Weight 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 Weight Converter upload your file to a server?
No. Weight 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 Weight Converter.
Do I need to install anything to use Weight Converter?
No installation is needed. Weight Converter runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use Weight Converter on a phone or tablet?
Yes. The Weight 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. Weight Converter keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
