Frequently asked questions
Is Favicon Preview free to use?
Yes. Favicon Preview is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does Favicon Preview upload your file to a server?
No. Favicon Preview 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 limit on how much input I can use?
Favicon Preview 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 Favicon Preview?
No installation is needed. Favicon Preview runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use Favicon Preview on a phone or tablet?
Yes. The Favicon Preview 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. Favicon Preview keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
