Frequently asked questions
Is Base58 Decoder free to use?
Yes. Base58 Decoder is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does Base58 Decoder upload your text to a server?
No. Base58 Decoder processes your text 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 limit on how much input I can use?
Base58 Decoder handles inputs into the megabytes without trouble; the only real limit is how much your browser tab can hold in memory.
Do I need to install anything to use Base58 Decoder?
No installation is needed. Base58 Decoder runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use Base58 Decoder on a phone or tablet?
Yes. The Base58 Decoder interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.
What happens to your text when I close the tab?
It is discarded. Base58 Decoder keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
